When are people infected with COVID-19 contagious?
Whether or not they have symptoms, infected people can be contagious and the virus can spread from them to other people.Laboratory data suggests that infected people appear to be most infectious just before they develop symptoms (namely 2 days before they develop symptoms) and early in their illness.
People who develop severe disease can be infectious for longer.While someone who never develops symptoms can pass the virus to others, it is still not clear how frequently this occurs and more research is needed in this area..
What is the main way that symptomatic people spread COVID-19?
COVID-19 is primarily transmitted from symptomatic people to others who are in close contact through respiratory droplets, by direct contact with infected persons, or by contact with contaminated objects and surfaces.
What is the incubation period of the coronavirus disease?
The incubation period of COVID-19, which is the time between exposure to the virus and symptom onset, is on average 5-6 days, but can be as long as 14 days. Thus, quarantine should be in place for 14 days from the last exposure to a confirmed case.
Who is at risk for serious problems from Covid 19?
See full answerMost people (about 80%) recover from the disease without needing special treatment, and for the majority – especially for children and young adults – illness due to COVID-19 is generally minor. However, for some people it can cause serious illness. Around 1 in every 5 people who are infected with COVID-19 develop difficulty in breathing and require hospital care.People who are aged over 60 years, and people who have underlying medical conditions such as diabetes, heart disease, respiratory disease or hypertension are among those who are at greater risk of developing severe or critical illness if infected with the virus.
What happens when you get the coronavirus disease?
People with COVID-19 generally develop signs and symptoms, including mild respiratory symptoms and fever, on an average of 5-6 days after infection (mean incubation period 5-6 days, range 1-14 days). Most people infected with COVID-19 virus have mild disease and recover.
Can you be contagious with COVID-19 if you have no symptoms?
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. 12-17 This is supported by data suggesting that some people can test positive for COVID-19 from 1-3 days before they develop symptoms. 6,16 Thus, it is possible that people infected with COVID-19 could transmit the virus before significant symptoms develop.
