With low COVID vaccination coverage in southern Africa, some have suggested global vaccine inequities may be responsible for the emergence of Omicron.
Disturbing the habitats of horseshoe bats, like these in Borneo, increases the risk of virus spillover.
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.
Experts estimate that close to 90% of the U.S. population must be vaccinated to reach herd immunity for 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.
Fruit bats are the main animal host of the nipah virus.

Virologists are beginning to assess which other viruses could have pandemic potential
Sticking garlic up your nose will not help you recover from a cold.
As winter approaches, every family has a favourite cold remedy, but experts say few work.
Bacteriophages are viruses that infect bacteria and play a potential role in the evolution of life.

Viruses have gotten a bad rap for the many illnesses and pandemics they’ve caused. But viruses are also genetic innovators – and possibly the pioneers of using DNA as the genetic blueprint of life.
Some institutions publish information about their mishaps, while others do not.

A centralized reporting system for laboratory incidents involving dangerous pathogens in biological research does not exist in the US or internationally.
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.
A security guard leads reporters away from the Wuhan Institute of Virology after a WHO team arrived for a field visit in Wuhan, Hubei province of China, Feb. 3, 2021. The team came to no conclusions about the origins of the pandemic.

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.
