WHO: 20,000 Could Be Infected Before Ebola is Under Control
The World Health Organization (WHO) now estimates that the ongoing Ebola outbreak in West Africa could infect as many as 20,000 people before public health officials are able to get it under control. The latest numbers on the disease place the number of infected at 3,069, with 1,552 deaths. Also yesterday, an article in the journal Science reported that the virus has mutated repeatedly during the outbreak, making it even more difficult to manage. Five of the report’s 50 co-authors have died of Ebola. Read more on Ebola.
CDC: Majority of Parents Have their Children Vaccinated
The majority of parents have their children receive routinely recommended vaccinations, according to the latest Morbidity and Mortality Report from the U.S. Centers for Disease Control and Prevention. The report found that in 2013:
- More than 90 percent of babies were vaccinated against measles, mumps, and rubella (MMR); poliovirus; hepatitis B; and varicella
- 73 percent were vaccinated against rotavirus
- 83 percent were vaccinated against Hepatitis A
- 74 percent were vaccinated against Hepatitis B
- Less than 1 percent of children received no vaccines
“I want to personally recognize the hard work of doctors and nurses coping with many challenges in the course of clinical work, and commend parents who, despite competing responsibilities, continue to prioritize immunization to keep their children healthy and safe,” said Anne Schuchat, MD, director of the National Center for Immunization and Respiratory Diseases. “These people are central in keeping young children healthy by ensuring they receive the recommended vaccines on schedule.” Read more on vaccines.
Study: Conflict Between Parents Also Causes Conflict with Children
Conflict between parents in a marriage also has a negative impact on parents’ relationships with their children, according to a new study in the Journal of Family Psychology. Researchers had parents in more than 200 families write daily diary entries for 15 days, then had each parent rate the quality of both their marriage and their relationships with their kids. They found that days with conflict between parents also had increased cases of problems between the parents and their children. "We see from the findings that the marriage is a hub relationship for the family. The quality of that relationship spills over into each parent's interactions with the child. So if mom and dad are fighting, it will show up initially—and in some cases on the second day—in a poorer quality relationship with their kids,” said study author Chrystyna Kouros, an assistant professor in the psychology department at Southern Methodist University, Dallas, in a university news release.

EBOLA UPDATE: Looted Quarantine Center Raises Fears of Ebola’s Spread
(NewPublicHealth is monitoring the public health crisis in West Africa.)
The raid by residents of an Ebola quarantine center in Liberia this weekend sent potentially infected patients fleeing and has raised very serious concerns over spreading the outbreak throughout West Point, Monrovia. Looters—apparently angry that patients were brought to the holding center from other parts of Monrovia—were seen taking items that were visibly stained with blood, vomit and excrement, all of which can spread the Ebola virus. The Washington Post reports that there have been talks about quarantining the entire township if needed. Read more on Ebola.
Study: Mothers in Poorer Health Less Likely to Breastfeed
Mothers who are in poorer health are also less likely to breastfeed their infant children, according to a new study in the journal PLOS ONE. Researchers from the School of Public Health at the University of Minnesota determined that women who are obese, have diabetes or have hypertension were 30 percent less likely to intend to breastfeed than were mothers without health complications. “Statistically we’re seeing an increase in breastfeeding in the U.S., which is great news. Unfortunately, at the same time, rates of obesity and other health problems are increasing. More than a million women each year enter pregnancy with a health problem, and our study shows that these mothers were less likely to plan to breastfeed,” said Katy Kozhimannil, PhD, lead author of the study and assistant professor at the university, in a release. “This is troubling because the families with social and medical risk factors are often those who stand to gain the most benefits from breastfeeding.” Read more on maternal and infant health.
Study: HPV Vaccine Still Effective After Eight Years
The human papillomavirus (HPV) vaccine appears to remain effective at protecting against the sexually transmitted virus for at least eight years, according to a new study in the journal Pediatrics. Researchers randomly assigned 1,781 sexually inactive boys and girls ages 9-15 to either the HPV vaccine or placebo shots, finding that those who received the vaccine still had antibodies against HPV after eight years. “The body's response against HPV by making antibodies looks very good at eight years, and it seems like no booster doses will be necessary," said lead researcher Daron Ferris, MD, director of the HPV epidemiology and prevention program at Georgia Regents University in Atlanta, according to HealthDay. "These are all indications that the vaccine is safe, and it looks like it's effective in preventing genital warts and other diseases caused by HPV.” Read more on vaccines.
The National Institute of Allergy and Infectious Diseases (NIAID), a division of the National Institutes of Health, is set to begin an early-stage clinical trial for a vaccine to protect against the Ebola virus. The trial should begin as early as September. The vaccine to be tested was developed by the NIAID’s Group Health Research Center in Seattle and does not contain infectious Ebola virus material. Instead, it’s what is known as an adenovirus vector vaccine containing an insert of two Ebola genes. The vaccine works by entering a cell and delivering the new genetic material, causing a protein expression that activates an immune response in the body. Researchers have seen success with studies in primates.
The vaccine being tested is not the experimental serum that was used on two Ebola-infected health workers recently evacuated from Liberia. In those cases, Samaritan’s Purse, the aid organization that sent the health workers to Africa, contacted officials from the U.S. Centers for Disease Control and Prevention (CDC) in Liberia to discuss the status of various experimental treatments they had identified through a medical literature search. CDC officials referred them to an NIH scientist in West Africa familiar with experimental treatment candidates who was then able to refer them to pharmaceutical companies working on experimental treatments. The serum being used is made by Mapp Biopharmaceutical of San Diego, Calif.

CDC: 60 Percent of Diners Will Use Menu Calorie Counts When Available
Approximately 6 in 10 U.S. adults will choose their restaurant meals in part because of menu label information when it’s available, according to the U.S. Centers for Disease Control and Prevention’s (CDC) latest Morbidity and Mortality Report. Researchers analyzed the self-reported usage of 118,013 adults in 17 states in 2012 to determine that about 57 percent will look to the provided calorie information. New York had the highest rate, with 61.3 percent, while Montana had the lowest, at 48.7 percent. Federal law requires calorie information be provided by any restaurant with 20 or more locations; while the regulations are not yet final, many establishments already voluntarily provide menu labeling, according to the CDC.

Depression, Stress, Hostility Tied to Higher Stroke Risk
Depression, stress and hostility may be linked to a higher risk for stroke, according to a new study in the journal Stroke. Using information provided by approximately 7,000 adults who did not have heart disease or a history of stroke at the beginning of the study, researchers followed up nearly nine years later and determined that depression was associated with an 86 percent increased chance of a stroke or a transient ischemic attack, stress was associated with a 59 percent increase and hostility doubled the risk. “[C]hronic stress and negative emotions are important psychological factors that affect one's health, and findings from this study link these factors to brain health in particular," said the study's lead author, Susan Everson-Rose, an associate professor of medicine at the University of Minnesota, according to HealthDay. "Patients and their health care providers should be aware that experiences of chronic stress and negative emotional states can increase risk for stroke.” Read more on heart health.
Washington State Sees Most Measles Cases Since 1996
A slight decline in Washington State’s mumps and rubella vaccination rate has coincided with the state’s highest number of measles case in 18 years, according to officials. Washington has reported 27 cases so far this year and is currently in the midst of its third outbreak. While homegrown measles was declared officially eliminated from the United States in 2000, infections from people who have travelled overseas remain a threat. There were 554 total cases of measles and 17 outbreaks reported in the United States between Jan. 1 and July 3 of this year. Read more on infectious diseases.
FDA: Sunlamps to Require Health Warnings
The U.S. Food and Drug Administration (FDA) has issued a final order that requires sunlamp products and ultraviolent (UV) lamps for use in sunlamp products to carry warnings stating that they should not be used by people under the age of 18. The order reclassifies the products from low-risk (class I) to moderate-risk (II). “The FDA has taken an important step today to address the risk to public health from sunlamp products,” said Jeffrey Shuren, MD, director of the FDA’s Center for Devices and Radiological Health, in a release. “Repeated UV exposure from sunlamp products poses a risk of skin cancer for all users—but the highest risk for skin cancer is in young persons under the age of 18 and people with a family history of skin cancer.” People who are exposed to UV radiation as a result of indoor tanning increase their risk of melanoma by 59 percent, according to the American Academy of Dermatology.

CDC: U.S. Measles Cases at a 20-year High
Cases of measles in the United States are at a 20-year high, with international travel by unvaccinated people a major contributor, according to the U.S. Centers for Disease Control and Prevention (CDC). The CDC reports that there were 288 U.S. cases between January 1 and May 23 this year—and 97 percent were associated with importation by travelers from at least 18 countries. Approximately 90 percent of the cases were in people who were not vaccinated or whose vaccination status was unknown. “The current increase in measles cases is being driven by unvaccinated people, primarily U.S. residents, who got measles in other countries, brought the virus back to the United States and spread to others in communities where many people are not vaccinated,” said Anne Schuchat, MD, assistant surgeon general and director of CDC’s National Center for Immunizations and Respiratory Diseases, in a release. “Many of the clusters in the U.S. began following travel to the Philippines where a large outbreak has been occurring since October 2013.” Read more on vaccines.
Type of Increased Heart Risk Depends on Which Blood Pressure Number is High
The type of increased heart risk a person with high blood pressure faces depends on which number in their blood pressure—the top, which is systolic, or the bottom, which is diastolic—is high, according to a new study in The Lancet. Researchers analyzed health care date on more than 1 million people ages 30 and older in England, finding that people with higher systolic blood pressure had a greater risk of bleeding strokes and stable angina, while people with higher diastolic blood pressure were more likely to be diagnosed with an abdominal aortic aneurysm. In addition, they found that a 30-year-old with high blood pressure has a 63 percent lifetime risk of developing heart disease, compared with 46 percent for a person with normal blood pressure. "With lifetime risks this high, the need for new blood pressure-lowering strategies is paramount," said lead investigator Eleni Rapsomaniki, MD, from The Farr Institute for Health Informatics Research in London, England, in release.

New NCHH, APHA Standards to Improve U.S. Housing Health
A new report from the National Center for Healthy Housing (NCHH) and the American Public Health Association (APHA) establishes new standards to help improve housing for all Americans. The new National Healthy Housing Standard outlines a health-focused property maintenance policy for the nation’s 100 million existing homes—single family, multifamily, rental and owner occupied. Approximately 40 percent of metropolitan homes have one or more health and safety hazards, according to the NCHH, while the American Housing Survey determined that approximately 6.3 million housing units are considered to be substandard. “While we have made great strides in improving the quality of housing nationwide, too many Americans are left making the false choice between affordable or quality housing. Families deserve access to quality and affordable housing that allows them to put down roots in a community, build wealth, put kids through college and start businesses,” said U.S. Department of Housing and Urban Development Secretary Shaun Donovan, in a release.

Red Cross Campaign Will Work to Cut Drowning in Half in 50 U.S. Cities
As part of its celebration of 100 years of swimming safety education, the Red Cross is launching a new national campaign to reduce the drowning rate by 50 percent in 50 U.S. cities. The 3-5 year campaign will target 50,000 people across 19 states. A new survey from the organization’s drowning prevention campaign found that while 80 percent of Americans said they could swim, only about 56 percent of those people exhibited “water competency”—meaning that they could perform these five critical water safety skills:
- Step or jump into the water over your head
- Return to the surface and float or tread water for one minute
- Turn around in a full circle and find an exit
- Swim 25 yards to the exit
- Exit from the water
“We're asking every family to make sure that both adults and children can swim and that parents make water safety a priority this summer,” said Connie Harvey, director of the Red Cross Centennial Initiative. Read more on injury prevention.
CDC Releases Vaccine Schedule App for Clinicians, Health Care Professionals
The U.S. Centers for Disease Control and Prevention (CDC) has launched a new app that provides clinicians and other health care professionals access to the CDC’s latest recommended immunization schedules. The CDC Vaccine Schedules app replicates the appearance of the printed schedules that are reviewed and published each year, and includes information such as the correct vaccine and dosage. The schedules include:
- Child and adolescent schedules with immunization recommendations from birth through age 18
- Catch-up schedule for children 4 months through 18 years
- Adult schedule, including recommended vaccines for adults by age group and by medical condition
- Contraindications and precautions table, with all footnotes that apply to schedules
The app is available in the iTunes App Store and will be released for Android devices in a few months. Read more on vaccines.
CDC Confirms First U.S. Case of MERS Virus
The U.S. Centers for Disease Control and Prevention (CDC) has confirmed the first U.S. case of MERS, a respiratory virus first identified in the Middle East two years ago. The virus was diagnosed in a U.S. patient who recently traveled from Saudi Arabia. The patient is being treated at a hospital in Indiana and people who traveled with the patient on an airplane from the Middle East are being contacted and told to see a doctor if respiratory symptoms develop. In some Middle Eastern countries, the virus has spread from person to person through close contact, but the CDC says there is no evidence of the sustained spread of the virus in general settings. "The virus has not shown the ability to spread easily in a community setting," said Ann Schuchat, MD, director of CDC's National Center for Immunization and Respiratory Diseases, during a telephone press conference on Friday.
"In this interconnected world we live in, we expected MERS to make its way to the United States....We have been preparing since 2012 for this possibility,” said Tom Frieden, MD, director of the CDC in a statement.
The CDC says that anyone who experiences respiratory illness within 12 weeks of traveling to Saudi Arabia, or becomes ill after contact with someone who recently traveled to Saudi Arabia, should contact their doctor. The CDC has not recommended that anyone change their travel plans based on the MERS virus. So far there have been 401 confirmed cases of the MERS virus in twelve countries, including the United States; 93 people have died of the virus. Camels have been identified as carriers of MERS, but it's not known how the virus is being spread to people. Read more on infectious disease.
WHO: World Polio Threat an ‘Extraordinary Event’ That Requires a Coordinated International Response
Despite the near cessation of the international spread of wild polio virus in the low transmission seasons (January to April) from January 2012 through 2013, a new report from the World Health Organization (WHO) finds that the current international spread of polio can now be considered an “extraordinary event.” WHO experts say the public health risk—the WHO Emergency Committee unanimously agreed that the conditions for a Public Health Emergency of International Concern (PHEIC) have been met—requires a coordinated international response. So far in 2014 there has already been international spread of wild polio virus from 3 of the 10 States that are currently infected: in central Asia (from Pakistan to Afghanistan), in the Middle East (Syrian Arab Republic to Iraq) and in Central Africa (Cameroon to Equatorial Guinea). Pakistan, Cameroon and the Syrian Arab Republic pose the greatest risk in 2014, according to the WHO. Read more on global health.
Study: Even Outbreaks May Not Change the Minds of Parents Opposing Childhood Vaccines
Parents who choose not to have their children receive mandatory immunizations may not change their minds even in the face of outbreaks of childhood illnesses, according to a new study. Researchers studied a pertussis outbreak in Washington State from October 2011 through December 2012, finding “no significant increase” in the vaccination rates of approximately 80,000 infants ages 3 to 8 months, according to HealthDay. Paul Offit, MD, chief of the division of infectious diseases at the Children's Hospital of Philadelphia, said parents using “personal belief” exemptions to not have their children vaccinate is likely beyond the resurgence of diseases that were once all but eradicated in the United States. "The problem is not theoretical,” he said. "You are starting to see eroding of herd immunity with outbreaks of measles and pertussis. The main reason is people are choosing not to vaccinate their children. It's becoming a more dangerous world from the standpoint of infectious diseases. Measles and pertussis are back. These are serious diseases that before vaccine caused a lot of death.” Offit was not a part of the recent study. Read more on vaccines.
Recently, we’ve been pleased to see increased engagement across a number of posts on NewPublicHealth, particularly from public health students. Reader comments have pointed a justly critical eye toward the way studies are often interpreted and presented. This level of conversation is critical to informing and bolstering NewPublicHealth’s coverage of public health news and issues.
We have compiled a handful of reader comments below, in an effort to continue the discussion.
- Readers shared their opinions on a survey showing that Hispanic adults are not confident in their understanding of insurance terms:
- “Although the concern of this study was the disparity between white literacy and non-white literacy, general focus should be placed on understanding for people in all racial categories. A lack of health literacy leads to many issues in health care, often resulting in ineffectiveness of care.” — Jessica H.
- “The study regarding the lack of understanding of key insurance terms is interesting because while it specifically shows low-literacy levels in Hispanics, it points to a larger problem in America. Relative to this study, literacy levels were highest in Whites and lowest in Hispanics. Overall, the literacy levels were universally low. This is a problem because being unable to understand insurance terms would lead to less effective use of the insurance, or no insurance at all.” — Michael
- Readers also questioned the validity of a study that found many parents support flu shots at school, based on concerns regarding data collection methods and information presentation biases:
- “Regarding the study that found that many parents support flu shots at school: The survey used in this study was given in English, but it was found that people most likely to agree to have their children vaccinated in a school setting included parents of uninsured children...If children are not insured, it usually means the parents are not insured and have jobs that do not provide health benefits. Immigrants usually work these kinds of jobs, and probably do not speak English well. So, if the survey was only given in English, this could influence the results of the study...” — Brittany
- “Surveys aren’t the best method of collecting data. Secondly, the convenience portion, which includes vaccine beliefs and or skipping past vaccines greatly contributed to the unwillingness to consent...And this would create a high stated consent rate, due to parental preferences based on location...Lastly, although the author wrote this study with intentions of public health official’s consideration to this topic I would be concerned since this study is the first to provide this information and does however contain many biases.” — Cora Neville
- “The article mentions that only parents who answered with a yes or not sure were asked follow up questions. If a parent answered no, was there a question that asked why they would not consent?...I think collecting data on those who declined the school-located vaccination would help future researchers find a way to get those parents who originally declined to consent.” — Shannen Mincey
- Many people in the public health field have publicly weighed in on the U.S. Food and Drug Administration’s proposed changes to food labels, including NewPublicHealth readers:
- I think some parts of this new regulation will be good for consumers while others will simply be a futile effort to help consumers eat better. For example, I believe adding “added sugars” to the label will be effective in identifying the bad sugar...One change that could be helpful for consumers would be to identify the types of fiber. Although the label includes total dietary fiber, this can be misleading to consumers who may not realize they are not getting nutritional value out of all of it.” — Jessica H.
- “Food labels need to be more understandable and consumer friendly. The Healthy People Campaign and health advocates, such as Michelle Obama want America to take responsibility for their health, yet the consumers have to dissect every food label to get a proper gauge of the nature of the food they’re consuming... On the same token, I think it is going to take a great deal of further research to determine what would be considered “better align[ed] with how much people really eat.’” — Vanessa Moses
Thank you to all our readers who have made their opinions known. Let’s keep these conversations going!
FEMA Issues Advisories as Severe Weather Hits Parts of the U.S.
The Federal Emergency Management Agency (FEMA) has begun issuing advisories for states across the Southern United States expected to be impacted by severe weather.
According to the National Weather Service, a major winter storm is impacting the South and Southeast ahead of moving up the Eastern Seaboard on Wednesday.
FEMA is encouraging both residents and visitors in the track of the storms to follow the instructions of state, local and tribal officials, and monitor NOAA Weather Radio and their local news for updates and directions provided by local officials. Residents can find trusted sources for weather and preparedness information via Twitter on FEMA’s social hub.
Weather Emergency Alerts (WEA) are currently being sent directly to many cell phones on participating wireless carrier networks. These alerts are sent by public safety offices such as the National Weather Service about imminent threats like severe weather. They look like a text message and show the type and time of the alert, any action you should take and the agency issuing the alert. Check your cellular carrier to determine if your phone or wireless device is WEA-enabled. Read more on preparedness.
Dozens of Bills Introduced in Recent Years to Increase School Vaccine Exemptions
From 2009 to 2012, 36 bills were introduced in 18 states to change school immunization mandates, with the majority aimed at expanding exemptions, according to a recent review in JAMA by researchers from Emory University. None of the bills passed, but the researchers say continued efforts to change state vaccine rules are concerning. Among 36 bills introduced, 15 contained no administrative requirements, seven bills had one or two administrative requirements, and the remaining 14 contained between up to five administrative requirements in order for parents to exempt their children from school vaccine rules in a given state.
"Exemptions to school immunization requirements continue to be an issue for discussion and debate in many state legislatures," according to the study authors. Read more on vaccines.
Being in a Good Mood Can Lead to Safer Sex
HIV-positive men are more likely to have save sex when their mood improves, according to a new study by researchers at the Mailman School of Public Health at Columbia University. The study, published in the journal Psychology, included 106 sexually active, HIV-positive men who have sex with men who completed weekly surveys over six weeks that asked about their sexual behavior, depression, and wellbeing during the prior week. Overall, 66 percent of study participants reported having unprotected intercourse in the prior two months; 81 percent had multiple partners. Three-quarters of the study participants were black and Latino men, a group disproportionately affected by HIV.
The researchers found that the men who reported an increase in their wellbeing in a given week were more likely to have safe sex (66%), while those who reported higher-than-usual levels of depression were more likely to engage in the risk behaviors (69%). The researchers are now studying potential interventions that might help address risky behaviors during depressive phases. Read more on sexual health.
Picture this: The world just ended. Well, not completely. But things aren’t looking up. An influenza strain has cut a deadly swath through nearly every continent. Or maybe the Black Death is making a special encore appearance. Or your now-undead neighbor—Phil, normally a great guy, invited you to a dinner party just last week—is shuffling around the front yard, trying to gnaw on your brains.
The point is it’s time for action. And since we’re talking theoretical, we might as well be talking fictional, too. Below is NewPublicHealth’s “Outbreak Dream Team”—pop culture characters with the diverse skills we’d need to respond to and cure a deadly epidemic. And maybe a dose of what’s really needed in the way of a public health workforce to keep us ready for whatever could happen next.
- In a nationwide (or global) public health emergency such as a pandemic, the President has to step up and provide leadership among different sectors and divisions of the government to coordinate a response and assure the nation of a secure path forward.
Laura Roslin, “Battlestar Galactica”
As a former Secretary of Education she has experience working with large groups with disparate goals. (Plus, she gets that education impacts health in so many ways). And as president of the roughly 50,000 humans left alive after a Cylon invasion wiped nearly everyone out, she’s adept at balancing public policy needs, working with everyone from public advocates to top military leaders. Some of her decisions are more-than-a-bit iffy, but you try pleasing everyone all the time when the last vestiges of humanity are spread across a fleet of ships drifting through space.
National Public Health Lead
- Equivalent to the Director of the U.S. Centers for Disease Control and Prevention (CDC). The CDC safeguards the nation’s health by preparing for, detecting, rapidly responding to and preventing health threats 24/7 to save lives and protect communities. The director’s job is to make sure that happens.
Ann Perkins, “Parks & Recreation”
As a practicing public health nurse and the PR Director of Pawnee's Health Department, Ann Perkins has dealt with infectious disease control from a hospital, a government and even a girlfriend perspective. Smart and determined, this go-getter can not only treat the symptoms of infectious diseases, she can detect and track them, coordinate response, and educate the community—all while maintaining a confident, calm and collected public face. While Leslie Knope leads the town through the city council, Ann has the potential to lead diverse teams and bridge health and health care to coordinate a swift and decisive response. If she can take on Pawnee's obesity epidemic one candy company at a time and teach sex ed to senior citizens, she can certainly handle a national outbreak or two. Plus, she gets bonus points for being (probably) the only true public health character on television.
