Officials report 5 new infections, expanding the outbreak to 923 cases.
“The boy required 57 days of inpatient acute care, including 47 days in the intensive care unit. The inpatient charges totaled $811,929 (excluding air transportation, inpatient rehabilitation, and ambulatory follow-up costs). One month after inpatient rehabilitation, he returned to all normal activities, including running and bicycling. Despite extensive review of the risks and benefits of tetanus vaccination by physicians, the family declined the second dose of DTaP and any other recommended immunizations.”

One of the remarkable, and most worrying, things about influenza is its ability to continually re-invent itself, either via a slow process of antigenic drift, or rapidly through antigenic shift (reassortment).
- Antigenic drift causes small, incremental changes in the virus over time. Drift is the standard evolutionary process of influenza viruses, and often come about due to replication errors that are common with single-strand RNA viruses (see NIAID Video: Antigenic Drift).
- Shift occurs when one virus swap out chunks of their genetic code with gene segments from another virus. This is known as reassortment. While far less common than drift, shift can produce abrupt, dramatic, and sometimes pandemic inducing changes to the virus (see NIAID Video: How Influenza Pandemics Occur).
While reassortment can occur with just about any influenza A virus, H5Nx subtypes appear unusually agile in this department, and genetic contributions from LPAI H9N2 can be found inside many avian viruses (see PNAS: Reassortment Potential Of Avian H9N2).
Kass is only the latest pro-vaccine health practitioner to be subjected to an online harassment campaign by anti-vaxxers. Networks of closed Facebook groups with tens of thousands of members have become staging grounds for campaigns that victims say are intended to silence and intimidate pro-vaccine voices on social media. The harassment only exacerbates an online ecosystem rife with anti-vaccine misinformation, thanks in part to Facebook’s recommendation algorithms and targeted advertising. “Their goal is to tell my patients what a bad person I am so I lose business,” Kass told the Guardian by phone, five days into his ordeal. “It’s made me reluctant to engage online.”

“Tonight another deplorable attack on an Ebola treatment facility has taken place, this time in the city of Butembo,” said Hugues Robert, MSF emergency desk manager, in a news release. “This follows the attack last week on another MSF Ebola treatment center in nearby Katwa. This attack has not only put the lives of Ebola patients and their families in danger, but also those of MSF and Ministry of Health staff.”
Doctors Without Borders (MSF) said today that it has suspended all activities at the Ebola treatment center in Katwa, following a violent attack over the weekend, severely limiting access to care in the Democratic Republic of Congo’s (DRC’s) main hot spot.

Of the 14 chemicals tested, every single member of every family had detectable levels. After switching to an organic diet, these levels dropped dramatically. Levels across all pesticides dropped by more than half on average. Detectable levels for the pesticide malathion, a probable human carcinogen according to the World Health Organization, decreased a dramatic 95% . Malathion was just one of the pesticides found in this study that are part of a group called organophosphates, which have long concerned public health experts because of their impact on children’s developing brains. Created as nerve agents in World War II, organophosphates have been linked to increased rates of autism, learning disabilities, and reduced IQ in children. The organophosphate chlorpyrifos, found in all of the family members, is so worrisome to public health that the Environmental Protection Agency (EPA) planned to ban it in 2017 – a proposal dropped by the Trump administration. In the wake of inaction from the administration, Hawaii passed the first state level chlorpyrifos ban in 2018; and Representative Nydia Velázquez introduced a federal bill to ban it.
Enterovirus species D genotype 68 (EV-D68) will be back in our media streams in 2020 as the biennial peak likely returns to cause more cases of acute flaccid myelitis (AFM) and severe respiratory illness. In
