As the 2019 coronavirus (COVID-19) begins to spread outside of China to other countries, many people are concerned and looking for answers. CLS Health addresses what is currently known about the novel coronavirus and how you can protect yourself.
How does the virus spread?
This coronavirus spreads from person to person primarily through close contact with respiratory droplets. You can protect yourself and others the same way you’d protect yourself from the flu, colds and other respiratory illnesses:
- Wash your hands with soap and water or use alcohol hand sanitizer, especially after being out and about in public and after blowing your nose, coughing or sneezing
- Avoid touching your eyes, nose and mouth
- Avoid close contact (within 6 feet) with people who are sick
- Stay home and away from others when you are sick
Can the virus be spread by asymptomatic people?
It is not entirely clear, but the available data suggest instances where people without symptoms, or perhaps with very mild symptoms appear to have transmitted to others. It’s likely not a major driver of transmission and people with the most symptoms are probably the most likely to transmit it.
Is COVID-19 more contagious than the flu or common cold?
COVID-19 appears to rival the flu or cold for how easily it’s transmitted. Epidemiologists use the term R0 (R naught) to estimate the individuals that each infected person will transmit to. The estimates of R0 for the coronavirus in China were somewhere between 2 and 3.5.
How deadly is COVID-19? How likely is it that someone with COVID-19 will require hospitalization?
There are still some unknowns, it appears that 15-20% of the cases are severe enough to require hospitalization and a significant fraction of that might require intensive care.
A recent study of cases in China, just published in JAMA, provides more insight into the age breakdown of the disease and its case fatality rate (how many of the people who get the disease end up dying from it).
Are kids at risk of getting COVID-19?
According to the JAMA article, out of the confirmed 44,672 cases, just 1% were in children younger than 9 and 1% in kids age 10-19.
What should you do if you think you’ve been exposed to coronavirus?
According to the Centers for Disease Control and Prevention, the current risk for the general American public is low.
Right now, specific travel history or exposure to persons with known COVID infections are the most predictive of whether respiratory symptoms could represent COVID infection.
If you have fever, cough, or difficulty breathing and have an exposure that is concerning for COVID, call your doctor ahead of time so that preparations can be made for you to wear an isolation mask and for staff to wear appropriate personal protective equipment while evaluating you.
If you do need to go to the emergency department, please share any travel or other exposure history immediately with health care providers so that appropriate precautions can be taken.
Note that the situation is constantly changing but steps can be taken to reduce your risk of getting sick. For the most up to date information, visit the CDC website.
