Remember how to avoid coronavirus infection

The increase in Covid-19 cases recorded in the last few weeks has made Brazil the fourth wave of a two-year pandemic. As the coronavirus circulates again, some precautions to avoid infection have been re-recommended by doctors to avoid the development of serious cases, deaths, and sequelae of long Covid. It is important to remember that reinfection is possible and anyone can infect the virus with the vaccine.

Infectious disease expert Ana Helena Germoglio assesses that the major changes between the current and previous waves are the characteristics of the less lethal and more contagious virus and the patient’s immune response. ..

“Most people are already immune to the coronavirus, either because of the vaccine or because they have had an infection before,” the doctor explains.

vaccination

The combination of complete vaccination (three doses of primary course and booster) and proper use of masks remains the greatest ally in the prevention of Covid-19, especially for immunosuppressed patients at high risk of coronavirus. Infection. This is due to the reduced natural defense of the body.

“Immune begins to decline about four months after immunization, so ideally you should take all available booster doses,” says Anna Helena.

mask

Returning to wearing a mask can be especially difficult for people who have readjusted to the world without a mask in the last few months. Still, items are one of the main ways to prevent infection. The most suitable models are the PFF2 / N95 and surgical masks that fit behind the head, but if there are no better options, experts point out that they are better than none and some cloth masks. Provides protection.

According to infectious scientists, when assessing an environment to decide whether to use a protective item, it is more important than observing whether it is open or closed to assess risk according to the number of people present. That is.

“If you’re in an open environment, but there are a lot of people around you, you’re also at great risk of getting infected,” he thinks.

In addition, Anna Helena needs to assess the individual risk of the population evolving to the severe form of Covid-19, taking into account risk factors such as age, comorbidities, and not completing the entire vaccination cycle. I remember that there is.

test

If you have initial symptoms such as cough, runny nose, fever, or sore throat, it is recommended that everyone undergo an antigen test or PCR to prevent the spread of the virus. Antigen-based self-tests can be purchased at pharmacies and done at home. Results will come out in minutes.

If the test is negative but the symptoms persist, the test should be repeated within 24 hours.

It is important to take the exam primarily to initiate quarantine. Without a diagnosis, the patient can continue to leave the home and infect others.

“Even with mild symptoms, the more infected people circulate and continue to infect the disease, the more persistent this cycle of viral infection,” says infectious scientists.

Social isolation for 7 days after the onset of symptoms in mild and moderate cases without fever continues to be shown to avoid the cycle of viral infection. If the patient continues to test positive on the 10th day, you should wait another 3 days before repeating the test.

Ana Helena believes that in the future, if the majority of the population is fully vaccinated, quarantine may no longer be necessary.
