"We've got national anxiety at the moment, a kind of shared stress, and we are all in a state of extreme uncertainty," says

, an associate professor at Northwestern University, Feinberg School of Medicine, who studies the role of fear and anxiety in health care.

And here's a catch-22: The more you stress, the more vulnerable you can become to viruses, because stress can dampen your immune response. 

But there are steps you can take to push back against the communal anxiety.

Those of us prone to anxiety like to be in control. So, if you take basic steps to prepare for the possibility of an outbreak in your community, you may feel a sense of relief. For instance, ask your employer about a work-from-home option. Be prepared for disruptions such as school closings. Have contingency plans for these disruptions. In addition, identify trusted sources of information you can turn to in the event of an outbreak.

"It's very important to say, well, no matter what happens, I've done the best that I can to be prepared," Belling says. 

It's important to be in the know. But you don't need to obsess over the news. "There's a point where, information gathering could become problematic," says 

 a psychologist at Northwestern University who studies anxiety. He says it could have the unintended effect of driving up your fear.

If you're taking basic steps to protect yourself and stay informed, that's enough. "There's no way to reduce your risk to zero," Shankman says. You could spend all day and night reading headlines, news alerts or tweets but this "does not change your risk of getting coronavirus."

Once you unplug from the news for a bit, why not try a 

 such as Headspace or Simply Being to help you let go of anticipatory anxiety. "We know from numerous studies that mindfulness is very effective at reducing stress and anxiety," Shankman says.

5) Wash your hands. Embrace the elbow bump

When an infectious disease hits a community, there's only so much anyone can do. You can't sterilize your entire environment. But taking a few preventative actions will help reduce your risk and hopefully relieve your anxiety. 

The coronavirus is transmitted from person to person via respiratory droplets. When an infected person sneezes or coughs, droplets containing virus particles are released. If you are standing close, you can become infected. "The respiratory droplets travel about three feet before they tend to settle out of the air, " says infectious disease expert 

of Brigham and Women's Hospital in Boston. Federal guidelines suggest 6 feet of separation, so keep your distance.

In addition, droplets can land on surfaces, such as elevator buttons, doorknobs, and shared work spaces. So, if you touch a contaminated surface, then touch your face, you can become infected. The virus can enter your body through your eyes, nose or mouth.

During an outbreak, proper hand-washing is your best defense against a virus. So, follow the evidence-based advice to wash for 20 seconds or more using soap and water. Or use hand sanitizers that contain
