In how many days does a person stop infecting Omicron

Due to the advancement of Ómicron, the demand for diagnostic tests grew in the world

The Omicron variant of the coronavirus was detected in November in Africa and in less than 2 months it spread throughout the world: it has already reached 149 countries. There is evidence to show that Ómicron has a substantial growth advantage over the Delta variant and has a doubling time of 2-3 days for community transmission.

If a person is infected with the Omicron variant today, they should be aware of how long the infection lasts and that it can infect others.

The Omicron variant is a more transmissible variant and generated an explosive increase in cases in most cities with community transmission. More than 312 million cases of Covid-19 have already been registered in the world, according to the World Health Organization. Since November, the circulation of Ómicron has grown until it becomes predominant and is displacing Delta.

Every time a person becomes infected, there is an incubation period, which is the time that elapses between infection by the virus and the appearance of symptoms of the disease. With the coronavirus there are cases of people who acquire the infection but do not have symptoms.


From the beginning of the pandemic, it was considered that the incubation period for coronavirus infection can range from 1 to 14 days, and on average around 5 days. For this reason, people who had been in close contact with a confirmed case were required to isolate themselves for more than 10 days. In the case of influenza, on the other hand, the incubation period is 2 days on average and ranges from 1 to 7. With Ómicron, the incubation period is two to three days.

The most common symptoms of Covid-19 are fever of 37.5 ° C, cough, sore throat, shortness of breath, rhinitis / nasal congestion, muscle pain, headache, diarrhea or vomiting. Sudden loss of taste or smell can also occur. In those cases, it is necessary to isolate oneself and consult the health system of the locality where the person is.

And when does the affected person stop spreading the virus?

“Today, based on the available evidence, it is known that 97% of People with coronavirus stop transmitting the virus after 7 days from the onset of symptoms. This change is due to the fact that the Omicron variant circulates and that a greater proportion of the population is already fully vaccinated. By being vaccinated, the risk of that person contaminating the virus if they become infected is reduced ”explained to Infobae Dr. Javier Farina, member of the Argentine Society of Infectology (SADI) and head of infectology at the Cuenca Alta High Complexity Hospital, in Cañuelas, Buenos Aires province.

It means that about seven days after symptoms appear, most people will no longer be contagious. That will happen as long as they no longer have symptoms. In the case in which the person has the virus but does not present symptoms, that is, it is an asymptomatic case, it is considered that the virus stops spreading after 7 days after the PCR has been performed.

In turn, Dr. Karin Kopitowski, director of the Research Department, University Institute School of Medicine, Italian Hospital of Buenos Aires and president of the Metropolitan Association of Family Medicine, commented: “Currently, it is considered that the person with Covid-19 You can spread the virus to others for 7 days. Therefore, they are recommended to do an isolation for a week. In completely vaccinated and asymptomatic people, it is probable that the time in which the virus can transmit is less ”.


Complying with the 7-day isolation is important to rest, recover, and care for others. Because the coronavirus is transmitted by being close to an already infected person, both indoors and outdoors. It is also transmitted from infected people and can become suspended in the air, especially in poorly ventilated places. People who breathe it out in drops or sprays can be infected without showing symptoms. A home in which people spend many hours a day together is a privileged place for contagion to occur.

The Omicron variant brought the pandemic into a new phase, with a “tsunami” of cases. Health care services are in high demand, and there is a shortage of tests available both in Argentina and in other countries. The technical head of the World Health Organization (WHO), María Van Kerkhove, asked on Wednesday that the risk of Cvodi-19 with the Omicron variant not be minimized.
