Influenza virus particles.
Two different respiratory viruses were found to swap proteins when they infected the same cell.
Evolution explains why the Delta variant spreads faster than the original Wuhan strain. It explains what we might see with future variants. And it suggests how we might step up public health measures.
It’s still reasonably easy to catch a cold even during lockdown.
Germs love your bed as much as you do.

You’ll probably want to wash your sheets after reading this.
COVID vaccines don’t contain any live virus to shed. Here’s the science to put the myth of viral shedding after the COVID vaccine to bed.
Spending more time in nature may be associated with less fear of germs.
A fear of microbes, like germs, could be harming human health.
Infection from the coronavirus can produce weaker immunity than vaccination.

COVID-19 vaccination produces a more consistent immune response than a past infection. With the delta variant, the difference in protection may be even greater.
You could say there are a ‘crapload’ of viruses in the human gut. Luckily, most of these do not attack our cells, but instead feed on bacteria.
Vaccination has saved millions of lives throughout the course of history.

Vaccines have successfully curtailed viral diseases for decades. But as COVID-19 vaccination hesitancy shows, mistrust and misinformation continue to put lives at risk.
Microbes are everywhere – and they aren’t all friendly.

Scientists get up close and personal with deadly pathogens to give doctors the tools they need to treat people sickened by germs. The key is keeping the researchers – and everyone around them – safe.
The prevention of future pandemics requires examining viral family trees.

Bat hosts, lab leaks – tracing SARS-CoV-2 to its origins involves more than just tracking down patient zero.

Gain-of-function studies make a natural virus more dangerous or transmissible to humans. Could the Wuhan Institute of Virology be the source of SARS-CoV-2?

The lab accident theory of the origins of Covid-19 has gained traction in recent months. We need a proper investigation to find out what really happened.
Sustained surveillance for disease outbreaks at global hot spots may be the key to preventing the next pandemic.
A more coordinated effort by scientists, stakeholders and community members will be required to stop the next deadly virus that’s already circulating in our midst.
Scientists have been trying to pinpoint the exact causes of the declines in some wild Pacific salmon populations for decades.
A study of viral variants finds Piscine orthoreovirus continuously spills over from farmed salmon to wild salmon.
Eating less animal proteins may help reduce the risk of future zoonotic viruses.

Pandemic viruses arise from raising, harvesting and eating animals. Policy strategy for averting the next pandemic should include supporting those already seeking to make plant-based dietary changes.
Fungal viruses have been important in reducing the impact of fungal diseases on chestnuts in Europe.
Technology is allowing scientists to better understand fungal viruses, with the aim of managing them more effectively.
Leeuwenhoek refined the magnifying glass, creating the world’s first microscope.

Van Leeuwenhoek, who discovered bacteria, is one of the most important figures in the history of medicine, laying the groundwork for today’s understanding of infectious disease.

Cuba’s access to internationally produced vaccines was nearly impossible due to the U.S. blockade. Its decision to make its own vaccines stands to pay off handsomely.
Pollen can suppress how the body’s immune system responds to viruses.

As climate change drives pollen counts upward, that could potentially result in greater human susceptibility to other viruses, as well.
