Hi dr i'm concerned about one of my collegues tested positive for covid .i work next to him at the office.i don't have any symptoms personally just worried. how long does someone have to be next to a carrier of the virus to be infected by that person?

COVID 19 spread: Per CDC , 6 to 12% of new COVID-19 cases are spread from asymptomatic individuals. People may shed the virus 1-3 days before symptoms appear. Many suggest contact for 10 minutes or longer ^'es risk. But, what was the distance between you & that person? Were masks/ face covers worn? If you are sprayed you with droplets from coughing or sneezing at close range you may contract it regardless.

See below: Covid-19: https://www.cdc.gov/coronavirus/2019-ncov/index.html Please contact your doctor by phone for further evaluation and mechanism for testing in your area. Wear a mask, stay away from others, practice hand hygiene. Be sure to get tested, if you get symptoms. If you develop breathing difficulty, go to the nearest hospital, immediately. Wish you good health.
