The possibility of presymptomatic transmission of SARS-CoV-2 increases the challenges of COVID-19 containment measures, which are predicated on early detection and isolation of symptomatic persons.

What is the difference between presymptomatic and asymptomatic cases of COVID-19?

A presymptomatic case of COVID-19 is an individual infected with SARS-CoV-2 who has not yet exhibited symptoms at the time of testing but who later exhibits symptoms during the course of the infection.

An asymptomatic case is an individual infected with SARS-CoV-2 who does not exhibit symptoms at any time during the course of infection.

A negative test result means that the virus that causes COVID-19 was not found in your sample. However, it is possible for this test to give a negative result that is incorrect (false negative) in some people with COVID- 19. You might test negative if the sample was collected early during your infection.

You could also be exposed to COVID-19 after your sample was collected and then have become infected. In particular, people infected with COVID-19 but who have no symptoms may not shed enough virus to trigger a positive test. This means that you could possibly still have COVID-19 even though the test result is negative.

Should I Get Tested for COVID-19?

Should I avoid touching surfaces when shopping during the COVID-19 pandemic?

Research suggests that COVID-19 is more commonly spread from respiratory droplets passed from people in close contact than from touching surfaces. It is possible but probably less common that those droplets land on surfaces, and then a person gets infected by touching their own mouth, nose, or eyes, after touching the surface (source). Washing your hands with soap and water (or using alcohol-based hand sanitizer) regularly and avoiding touching your face will help with this concern. Another important way to avoid getting the virus while shopping is to wear a mask and stay at least 6 feet away from others.
