COVID-19 continues to spread and severely impact Brazil and the world. People of all ages are being infected, but as we already know, people with diabetes appear to be more vulnerable present more severe symptoms, due to the difficulty in fighting the virus, due to variations in blood glucose levels and, possibly, due to the presence of complicationsalready pre-existing, derived from diabetes.
Understand what the coronavirus is
we must understand like our immune system, it responds to infection by COVID-19, being essential to design an exit strategy for the 2020 pandemic .
Much of the debate about how we can lift restrictions revolves around the need to a proven antibody test that seek their presence in our body.
This is the point in question: If we could find out who was infected and who recovered, and if these people could prove that they were immunized against the virus again, would it be possible to allow them to go back to work and socialize with friends and family?
Understand how antibodies work
Antibodies are proteins produced by the body’s defense system, the so-called immune system, to defend our body from invaders such as: a virus or bacteria, the so-called pathogens.
Antibodies destroy the pathogen by binding to it, so it can render it harmless or mark it for destruction by defense cells.
Antibodies normally remain in the bloodstream after an infection, in case the virus infects you again. If this happens, the immune response will be much faster.
Is there a possibility of contracting coronavirus 2 times?
Patients who have recovered from a virus are resistant to reinfection. In fact, for most viruses, the first time you’re infected, your body takes time to develop the necessary antibodies, but it’s better prepared to fight off the infection a second time.
We are all anxious for a vaccine against COVID-19, hoping that everything will return to normal. Is not the same?
THE SIBM – Brazilian Society of Immunization – defines a vaccine as “a preparation capable of inducing an immune response in the individual who receives it, so that, once exposed to a pathological agent, it already has protective antibodies”.
While we wait for the long-awaited coronavirus vaccine, we must continue:
- wash hands,
- maintain social isolation
- avoid crowds
- and wear face masks that cover the nose and mouth.
This care is not only for those who have not yet been contaminated by the virus, but it is for all people.
What do the studies show?
Recent studies have confirmed at least five reinfection cases in some countries. From April/2020 to World Health Organization it has been discussed whether it was possible to have COVID-19 more than once. Now it seems the answer is “Yes”although it is extremely rare and more research is needed to fully understand the possibility of reinfection.
in one of recent studies on a confirmed case of COVID-19 reinfection in the United StatesThe researchers found evidence that a person with no known immune problems or poor health conditions was infected with COVID-19 in two separate cases.
The 25-year-old male patient was infected with two distinct variants of COVID-19 over a 48-day period, testing negative between infections.
After experiencing severe COVID-19 symptoms again, including fever, headache, dizziness, cough, nausea, and diarrhea, the patient was hospitalized and tested positive a second time.
According to the investigators, the patient’s second infection was more severe and resulted in hospitalization with oxygen support. The patient has since been discharged from the hospital and has recovered from the second infection.
What are the chances of coronavirus reinfection?
various hypotheses were raised to try to explain the severity of the second infection. One of them is the possibility that the patient, after being infected for the first time, had contact with a greater amount of the virus that caused a more acute reaction the second time. the other hypothesis is that the patient may have been in contact with a more powerful version of the virus.
In the opinion of the researchers, the five cases of reinfection indicate that previous exposure to COVID-19 may not translate into a guarantee of full immunity. Despite, more research is needed on reinfections.
According to one of the leading researchers, Dr. Pandori, we need to deeply understand how long the immunity of people exposed to COVID-19 can last and why some of these second infections, although rare, turn out to be more serious.
The researchers strongly suggest that people who have already been infected with COVID-19 continue to take serious precautions when it comes to the virus, with an emphasis on handwashing, social isolation, and wearing masks.
