Certain viruses like dengue and Zika can make their hosts smell tastier to mosquitoes. Luckily, vitamin A and its derivatives may help combat these odor changes.

Sepsis onset can be difficult to recognize, in part because its symptoms can mimic those of many other conditions. A treatment delay of even a few hours can make the difference between life and death.

Viruses do more than just cause disease – they also influence ecosystems and the processes that shape the planet. Tracing their evolution could help researchers better understand how viruses work.

The latest addition to the omicron lineage has been making waves in Europe. Whether it will do the same in the U.S. depends on rates of vaccination and prior infection.

Scientists have been testing captive and wild animals for the coronavirus since the pandemic began. Only a few wild species are known to carry the virus, but many more have been shown to be susceptible.

Some cancers are actually caused by viruses that linger for long periods in the body, or cause physical damage that later turns cancerous.

Masks definitely catch some of the virus laden aerosols and droplets - and that will reduce transmission between people and the number of cases of COVID-19.

Vaccination campaigns like the ones that eventually eliminated polio and measles in the United States required decades of education and awareness in order to achieve herd immunity in the U.S. population.

How can nations prevent more pandemics like COVID-19? One priority is reducing the risk of diseases’ jumping from animals to humans. And that means understanding how human actions fuel that risk.
