What does presymptomatic mean in relation to COVID 19?

What does pre-symptomatic transmission of COVID-19 mean?

The incubation period for COVID-19, which is the time between exposure to the virus (becoming infected) and symptom onset, is on average 5-6 days, however can be up to 14 days. During this period, also known as the “pre- symptomatic” period, some infected persons can be contagious. Therefore, transmission from a pre-symptomatic case can occur before symptom onset.

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.

What is an asymptomatic case of COVID-19?

An asymptomatic case is an individual who has a laboratory confirmed positive test and who has no symptoms during the complete course of infection.

For people who are infected but asymptomatic (never develop symptoms), isolation and precautions can be discontinued 10 days after the first positive test.

What is the main route of transmission of COVID-19?

The main route of transmission of COVID-19 is through respiratory droplets generated when an infected person coughs or sneezes. Any person who is in close contact with someone who has respiratory symptoms (e.g., sneezing, coughing, etc.) is at risk of being exposed to potentially infective respiratory droplets. Droplets may also land on surfaces where the virus could remain viable for several hours to days. Transmission through contact of hands with contaminated surfaces can occur following contact with the person’s mucosa such as nose, mouth and eyes.

How long are you contagious if you are an asymptomatic carrier of COVID-19?

The Centers for Disease Control and Prevention recommends a 10- to 14-day quarantine period for anyone testing positive for the virus. The research from South Korea, however, found that asymptomatic people were contagious for about 17 days and those with symptoms were contagious for up to 20 days.
