COVID-19 has been found in pets, zoo animals and in a wild mink in Utah. Monitoring wildlife for COVID-19 is important for animals and humans, both of whom face risks from a jumping virus.
Before the U.S. can return to some form of normal, a lot of people need to be vaccinated.

Researchers say around 70% of the US needs to get the coronavirus vaccine to stop the pandemic. But questions around the vaccines and regional differences add some uncertainty to that estimate.
Holiday events will need to be a little different due to the pandemic.

COVID-19 and holiday family gatherings are not a good pair. But taking the right precautions before, during and after the family gets together can greatly reduce coronavirus risk this holiday season.
A designated coronavirus hospital would relieve pressure on the state’s health-care system and minimise the spread of the virus, but there are a few things to consider.
Good ventilation can reduce the risk of catching coronavirus. An environmental engineer explains how to know if enough outside air is getting into a room and what to do if ventilation is bad.
Children are at risk of getting sick from coronavirus and need to practice social distancing and mask wearing too.

Research shows that children can become infected with the coronavirus and spread it to others. Though rare, some kids do become severely ill and a few have died from COVID-19.
The U.S. as a whole is facing a huge surge in coronavirus cases, but the differences between states like New York and Florida are striking.

The recent spike in new coronavirus cases in the US is not due to a second wave, but simply the virus moving into new populations or surging in places that opened up too soon.
Screening for symptoms can catch some cases of COVID-19, but about people who are infected but not showing any symptoms?

There is a lot of confusion and concern around asymptomatic spread of SARS-C0V-2. An infectious disease expert explains how many people are asymptomatic and how they can spread the virus.
Quaranteams offer a way to limit the risk of infection while also maintaining social contacts and mental health.

People are turning to quarantine bubbles as a way to see friends and family while limiting the risk from the coronavirus. Research shows that this can work, but it’s not easy to be in a quaranteam.

Pathogens typically face a trade-off between virulence and transmission. But that’s not the case with SARS-CoV-2.
Coughing, sneezing, talking and even just breathing can produce airborne particles that can spread SARS-CoV-2.

SARS-CoV-2 can be spread through the air. But just how much of a factor that is has been hard to determine. Recent evidence suggests it is common, posing problems as public places begin to reopen.
Evidence is growing that when masks are worn by nearly everyone, it can slow coronavirus transmission.

Recommendations around mask usage are confusing. The science isn’t. Evidence shows that masks are extremely effective to slow the coronavirus and may be the best tool available right now to fight it.
From your lungs into the air around you, aerosols carry coronavirus.

Aerosols are the tiny particles of liquid and material that float around in our environment. When they come from an infected person, they may be a significant source of coronavirus transmission.
Our pets are always close at hand. Are they at risk during the pandemic?

Both cats and dogs can become infected with the coronavirus. The chances of them getting sick or passing it on to you or another animal are extremely low.
Traveling is risky during the coronavirus outbreak. Places like airports, bus stops, and gas stations especially so.

Universities and colleges around the world are closing. People are fleeing from cities. Some people are being forced to move but others must weigh the risks and ethical concerns of travel.
