Spread Out Break Work मुफ़्त में

Just how easily the virus can spread is not yet clear. But a recent study that focused on the first 425 cases in China suggested that the virus has a basic reproductive value of 2.2, meaning that each case-patient could spread the virus to about two other people.

See full answerCOVID-19 is a new disease, and we are still learning how it spreads. The virus that causes COVID-19 is thought to mainly spread from close contact (i.e., within about 6 feet) with a person who is currently sick with COVID-19. The virus likely spreads primarily through respiratory droplets produced when an infected person coughs or sneezes, similar to how influenza and other respiratory infections spread. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. This type of spread is not a concern after death. It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads.

See full answer asymptomatic laboratory-confirmed case is a person infected with COVID-19 who does not develop symptoms. Asymptomatic transmission refers to transmission of the virus from a person, who does not develop symptoms. There are few reports of laboratory-confirmed cases who are truly asymptomatic, and to date, there has been no documented asymptomatic transmission. This does not exclude the possibility that it may occur. Asymptomatic cases have been reported as part of contact tracing efforts in some countries. WHO regularly monitors all emerging evidence about this critical topic and will provide an update as more information becomes available.

From the evidence so far, the COVID-19 virus can be transmitted in ALL AREAS, including areas with hot and humid weather. Regardless of climate, adopt protective measures if you live in, or travel to an area reporting COVID-19. The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose.

Recently published research found that on average, the time from exposure to symptom onset (known as the incubation period) is about five to six days. However, studies have shown that symptoms could appear as soon as three days after exposure to as long as 13 days later.

asymptomatic transmission may occur and has contributed to a limited amount of transmission of COVID-19 infections. People can shed the virus before they have symptoms, but this is generally less than individuals with symptoms.

Someone who has been released from quarantine is not considered a risk for spreading, according to the CDC.

It is still not certain how long the coronavirus survives on surfaces. Preliminary studies suggest that the virus can persist for a few hours up to several days.
