The risk of re-infection with Covid-19 is 16 times higher since Omicron became the “dominant” strain
It is completely possible to re-infect many times
Currently, studies around the world have shown that the Omicron variant can overcome the immune barrier created by the vaccine, increasing the number of COVID-19 re-infections.
Specifically, according to a report by the UK Office for National Statistics, in recent months, there has been a sharp increase in the number of COVID-19 re-infections after randomly sampling households across the country.
In particular, the risk of reinfection was 16 times higher between December 2021 and early January 2022 when Omicron became the dominant strain compared to the Delta variant.
Similarly, data collected from South Africa also shows Omicron’s immune-attacking properties, with a higher rate of reinfection than in previous waves.

Experts say that when infected with COVID-19, the body will create immunity, but not all immunity is sustainable because there will always be a decrease in antibody levels in the blood. Not to mention with recent new strains of COVID-19 that will penetrate the cells in the body very quickly without the antibodies being able to respond.
According to Dr. Pham Quang Thai, Deputy Head of the Department of Infectious Disease Control, Central Institute of Hygiene and Epidemiology, the SARS-CoV-2 that causes COVID-19 is constantly changing. The new strain can evade the pre-existing immunity in the patient’s body.
Therefore, medical experts believe that anyone can be re-infected with COVID-19, even re-infected many times if they do not follow the principles of disease prevention.
Doctor Truong Huu Khanh, Standing Vice Chairman of Ho Chi Minh City Infectious Diseases Association, also warned that people who have not been vaccinated or have weak health and weak immunity will be more susceptible to being re-infected with COVID-19 than those who have not been vaccinated. others. In addition, the group of people over 65 years old, people who often use immunosuppressive drugs and people with many underlying medical conditions, especially hypertension, diabetes are also at high risk of re-infection with COVID-19.
According to doctors, although the rate of re-infection with COVID-19 is not high and often has milder symptoms, it should not be underestimated because those who are re-infected are people with reduced immunity, advanced age, and many underlying diseases. This is an opportunity for these diseases to recur, causing many life-threatening complications.
Is Covid-19 re-infection really milder?
According to Dr. Pham Quang Thai, Deputy Head of the Department of Infectious Disease Control, Central Institute of Hygiene and Epidemiology, the results of many studies show that the re-infection episodes will be milder than the first infection, even though the previous F0 is encountered any variation. Or even if antibodies are not strong enough to protect against a second infection, they can still prevent the disease from getting worse and reduce the risk of death.
Do not be subjective even though you have been negative for COVID-19
However, there is still a small percentage of patients who experience serious complications after re-infection with COVID-19, which depends on the time when the disease is too close together and the background of each patient.
Therefore, experts recommend, people with COVID-19 who have recovered from the disease should not be subjective, negative does not mean that they have “escaped”, having built lifelong immunity.
After recovering from illness, the body still needs to recover from the virus attack. It is necessary to strengthen the immune system by exercising, supplementing with proper nutrition, and especially by following the 5K principle to fight new attacks of the disease-causing virus.
