The number of victims is increasing sharply in many countries of the world Govt, Powered by Omigron, a new variant of the virus.
But as Omigran spreads, it becomes clear that the symptoms and diseases it causes are less severe than those caused by its predecessors. BBC.
This means that people who are infected, especially if they are vaccinated, are less likely to be hospitalized or die.
That is why many countries are reviewing their rules regarding the isolation period required for people with Govt disease.
Here we explain how the Omigron variant changes what has been seen so far about corona virus infection.
How long does it take for a person infected with the virus to develop symptoms?
Although there are still some studies on Omigran, what has been found so far is that this variant is not only more contagious, but has a shorter incubation period than previous varieties.
Incubation is the time elapsed from the onset of the virus until the onset of symptoms.
In the first type of corona virus, symptoms usually appear within five or six days after infection. With the delta variation they appeared in four days.
But from what has been known so far by Omigron, the incubation period is two to three days.
“basically [con ómicron] The response seems to be very fast, ”explains BBC Mundo Dr Vicente Soriano, a physician and former consultant who specializes in infectious diseases and clinical genetics. World Health Organization.
“After sneezing in the face, reflection [del virus] It starts in a day and after two days it is already diagnosed [con síntomas]“Adds a professor at the International University of La Rioja in Spain.
In fact, an initial study of six cases of Omigran in the United States, published in December, found that the average incubation period was three days, compared to five days for other species.
How long can an infected person be at risk of infecting others?
It is known that people are most contagious at the beginning of their infection.
With Omigran, it is believed that the virus spreads one to two days before the onset of symptoms and two to three days after.
“We believe the virus will only be contagious for five days. In other words, the ability to infect others, the ability to spread the virus for three to five days, the test is positive, it’s the second day of infection,” the expert said.
Therefore, with Omigron, the time it takes for the virus to remain in the body is only seven days.
“But this is medicine, not math, so you have to pay a little margin. Little by little, three or four days, others last seven days. The fact is that the infection in Omigran is much faster than in the previous generation, “said Vicente Soriano.
This means that about seven days after the onset of symptoms, most people will no longer be infected until symptoms appear.
The expert emphasizes the importance of performing antigen tests (also known as rapid lateral flow tests) to find out if the person is still infected.
“They are the best response to cheap trials and events that are still contagious.”
Since Omigran appears to have a shorter duration of infection than other types, many countries have reduced the time required to isolate victims.
In the United States, isolation was reduced from 10 to five days, and in the United Kingdom, it was reduced to 10 to seven days with evidence of two negative antigen tests.
When can I be with others if I have goiter and have symptoms?
According to the US Centers for Disease Control and Prevention (CDC), if you’ve tested positive for Govt, you’ll definitely have:
- Isolate at home for five days.
- If you have no symptoms or your symptoms improve after five days, you may leave the isolation and leave your home.
- Continue to wear the mask while you are with others for another five days.
- If you have a fever, stay home alone until the fever is cured.
What happens if the victim has no symptoms?
With goiter it has been found that there are people who do not show symptoms for the whole time of the infection.
Epidemiologist Vicente Soriano explained that with Omigran, it is expected to be similar to an infection with asymptomatic symptoms.
“Not much is known about asymptomatic infections, but the duration of the infection should be the same as for individuals with symptoms,” he says.
“There are studies of covit in children who usually do not show symptoms, and even if they do not show symptoms, it does show that they have the same viral load as adults with symptoms.”
Experts point out that a person who is positive for Kovit but does not develop symptoms will not get the infection after 10 days.
Can a person who has no symptoms spread it to others?
Studies show that people with asymptomatic goiter can spread the corona virus to others.
A study published in the journal JAMA Network Open (Journal of the American Medical Association) found that a quarter of infections are transmitted by people with asymptomatic infections.
The rate of asymptomatic transmission is thought to be even higher with the Omigron variant.
People without symptoms are more likely to spread the infection because they do not isolate themselves and do not follow behaviors to prevent the virus from spreading.
That is why authorities recommend the use of masks, especially at home, to help reduce the risk of infection spreading unknowingly to others who have not experienced the symptoms.
