Trump’s bid to end HIV transmission in America by 2030 could miss the mark by focusing too narrowly on medical approaches, advocates warn.   Medicines like antiretrovirals and pre-exposure prophylaxis are needed and available, but many populations most in need are missing…

Ebola survivors in Liberia show a higher burden of certain health problems than a control group, according to an ongoing study published in the New England Journal of Medicine that has tracked people for 5 years.  

“Antimicrobial resistance is a more immediate threat to human health than climate change,” writes epidemiologist Steffanie Strathdee, and it’s worsening with overuse of antibiotics and a lack of alternatives.   Phage therapy—using bacteriophages, or viruses that only attack…

When researchers resurrected the extinct horsepox virus, critics charged they gave away the plans on reconstructing a cousin of smallpox, which killed hundreds of millions.

Researchers have posited another benefit of reducing obesity rates: limiting the toll of viral infectious diseases. According to a study of Nicaraguan households spanning 3 flu seasons, the influenza A virus sheds longer in obese people because of chronic inflammation…

Global warming is allowing an array of forgotten pathogens to emerge from the thawing permafrost—and possibly reinfect humans.   Organic matter like dead animals, moss and plants, long preserved in ice, are now thawing, rotting, and releasing gases that not only spur global…

Each species of bat could unleash 17 zoonotic infections—those that jump from animals to humans—while every species of primate and rodent could launch 10, according to predictions of a new study by EcoHealth Alliance published in Nature.

There’s more bad news about the H7N9 bird flu virus, which caused a surge in human infections this spring. With just a few genetic tweaks, H7N9 could pass from human to human, according to a PLOS Pathogens study published yesterday.  

In subtropical regions, where flu viruses can circulate 8-12 months of the year, vaccinating pregnant women year round could yield dramatic health gains for mothers and and babies, according to a Nepal-based study in Lancet Infectious Diseases (paywall).  

Two researchers in Switzerland and the US have won the Open Science Prize for a genetic tool that maps how viruses spread in real time.   Richard Neher, of the University of Basel, and Trevor Bedford, of the Fred Hutchinson Cancer Research Center, will each get $115,000 to…
