MYTHS AND TRUTHS ABOUT COVID 19:
Asymptomatic patients are not contagious: Lie
There are many viruses that behave like COVID and can spread asymptomatically such as HIV or Hepatitis, and that does not make them lose the contagion capacity they have.
The contagion of the coronavirus depends only on the viral load: a lie
The contagion of any virus depends on many factors: the viral load, the response of our immune system, the conditions in which we find ourselves with the infected person (open or closed space, amount of time we spend with him / her), etc. .
If I do a COVID PCR and it comes out negative I can be 100% sure that I do not have Coronavirus: A lie
COVID has a window period of 5 to 7 days. That means the test has the ability to measure from those 5 to 7 days back.
The virus can infect children and adults alike: True
Having coronavirus antibodies protects against reinfection: Truth
Everything seems to indicate that having IgG protects against future reinfections. There has been a lot of talk lately about people who have been reinfected but this fact has not been documented, in some cases they have been failures of some tests, so what is known so far is that YES.
IgG antibodies disappear too soon: True
It has been seen that the majority of patients who were IgG positive lost it within two months of their infection.
Cytotoxic T lymphocytes give us immunity: True
It seems that people who have not developed antibodies and who have passed the virus asymptomatically or not, had cytotoxic T lymphocytes, and these give immunity.
Coronavirus and pregnancy:
Vertical transmission (from mother to child) is very difficult: True
Pregnant women are at high risk for COVID: It is not known and information is lacking. What is known is that pregnancy is a period of important changes at the
Cured patients can spread the virus: Truth
Once cured, they can still have enough viral load to spread it to other people, so it is important that they keep a quarantine period to avoid it. To avoid this 14-day quarantine, the person can undergo other tests (rapid test or serology) that will indicate the progress of the infection and thus be able to return to normal life.
