When does a person with COVID-19 start being contagious?

Researchers estimate that people who get infected with the coronavirus can spread it to others 2 to 3 days before symptoms start and are most contagious 1 to 2 days before they feel sick.

Hence, Is presymptomatic transmission of COVID-19 possible? 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.

Indeed, Can pre-symptomatic transmission occur with the coronavirus disease?

In a small number of case reports and studies, pre-symptomatic transmission has been documented through contact tracing efforts and enhanced investigation of clusters of confirmed cases. This is supported by data suggesting that some people can test positive for COVID-19 from 1-3 days before they develop symptoms. Thus, it is possible that people infected with COVID-19 could transmit the virus before significant symptoms develop. It is important to recognize that pre-symptomatic transmission still requires the virus to be spread via infectious droplets or through touching contaminated surfaces.

What does presymptomatic mean in relation to COVID-19? Presymptomatic means you’re infected, and you’re shedding the virus. But you don’t yet have symptoms, which you ultimately develop. Unfortunately, the evidence suggests that you may be most contagious in the presymptomatic stage before you have any symptoms.

Then, What is the difference between people who have asymptomatic or pre-symptomatic COVID-19?

Both terms refer to people who do not have symptoms. The difference is that ‘asymptomatic’ refers to people who are infected but never develop any symptoms, while ‘pre-symptomatic’ refers to infected people who have not yet developed symptoms but go on to develop symptoms later.

How many COVID-19 patients are asymptomatic?

The South Korean estimate of 30 percent is slightly lower than the asymptomatic figure offered by Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases. He said roughly 40 percent of Americans with COVID-19 are asymptomatic.
