WHO explain how heterogeneous people spread covid-19
Here’s how someone with no symptoms can spread coronavirus
We all know that COVID-19 spreads to people who have the virus. A person removes the virus when a corona virus coughs, sneezes or speaks. But, what happens in the case of asymptomatic COVID-19 patients? Can they spread the virus? The World Health Organization, in a recently released video, answers similar questions related to the COVID-19 broadcast.
What do you want to know
COVID-19 Technical Lead Dr. Maria van Kerkhov states that most of the transmission known so far is that people who have symptoms carry the virus through infectious droplets to other people. “But, there is a subgroup of people who don’t develop symptoms. We still don’t have the answer to understand how many people don’t have symptoms,” he says.
What does it mean to be asymptomatic or pre-symptomatic?
In the video, Dr. Kerkhov states that asymptomatic COVID-19 positive means a person is tested positive, but has no symptoms, and does not tend to develop symptoms. “Many people are reported asymptomatic, may actually have milder diseases. They can go on to develop symptoms. They can’t quite register that they’re sick. They just feel a little bit unwell. Or under the weather, or suffering from fatigue. ” In those individuals we would classify them as pre-symptomatic, ”she says. Pre-symptomatic COVID-19 positive means that a person has not yet developed symptoms.
Is it possible to spread the infection if there are no symptoms?
Viral shedding studies for some lab work suggest that people who are infected with COVID-19 may test positive one to three days before symptoms develop. “This is something that has been known for some time. We need to understand what proportion contributes to transmission. It is one of the major unknowns,” Dr. Kerkhov says.
How can asymptomatic people spread the virus?
Dr. Mike Ryan, EXD, WHO Health Emergency Program, explaining how the virus can spread to people, “For example, if someone is in a nightclub, trying to talk to someone, and its very noisy.” Is, and you are very close to them., It is as if you are projecting your voice at someone. In this case, if the virus presents to your upper respiratory mucosa, there is every possibility that you can project the virus. Huh. “
Many people with COVID-19 experience only mild symptoms, especially in the early stages of the disease. “It is possible to catch COVID-19 from someone who just has a mild cough and does not feel ill. Some reports have indicated that people without symptoms can transmit the virus. It is still It is not known how often this happens. WHO assesses. Ongoing research on the subject, “the WHO website states.
What is the situation now?
In the last few days, the highest number of daily cases have occurred in the world. Therefore, in terms of the origin of the epidemic, we are still very high uphill on this mountain, Dr. Ryan says. “As some countries have shown, if you look at it in a very systematic way, with a broad view, there is enough prevention for the virus.”
He further states that as a society, we have some options to make. “If we can identify cases and their contacts, and we ask those contacts to quarantine themselves, we support them in that quarantine, it will prevent disease and avoid mass lockdowns in the future Both can have a very successful method.
