Can we get reinfected by omicron?

It is very common these days to see how some family members who end their isolation due to Covid-19 take over from other members.

For example, a mother gets the long-awaited negative and, two days later, one of her children tests positive.

What should we do in these cases?

Is it safe to live with a positive person and lead a "normal life" if we have just passed the disease?

Dr. Fauci, presidential adviser on infectious disease issues in the United States and one of the world's leading experts in this field, spoke on the issue a few days ago.

He explained that, indeed, reinfections do exist, but that if a good immune response is mounted,

, at least for a few months.

In the unlikely event that this did occur, the infection would usually pass mildly.

What are the most likely causes of reinfection?

Although it is necessary to continue investigating the capacity of reinfection by

, when this occurs in a short space of time it is usually due to:

1. Infection by different variant.

Let us remember that, although the omicron variant is the queen, delta is still among us.

In the event of a reinfection, the most likely scenario is that we have first been infected by the delta variant and later by omicron, which, as it breaks all the rules, is capable of circumventing the immunity created against delta.

2. Same unresolved infection.

There are people who can continue to test positive for PCR for weeks, although in general with low contagion capacity. As a curiosity, the Ministry of Health considers reinfection to be suspected when more than 90 days have passed since the previous one. 90 days have been considered to avoid confusion with cases that test positive for a long time. In short, someone could test negative for antigens, consider their infection to be over... and yet continue to be PCR positive for weeks without knowing it. If you are in close contact later and have a PCR, you might think that your positive is recent and that it is a reinfection, even though it is not.

3. Reactivation of unresolved infection.

Although it is not common either, it is possible that a person who has ended their isolation but continues to have a low viral load, can reactivate their infection by coming into contact with the virus again and stimulating their immune system.

What can we do to avoid reinfection?

If we talk about coronavirus we must remember that the basic physical laws of magnetism are not fulfilled.

You know, the thing about positive poles repelling each other while positive and negative poles attract each other.

In terms of contagion, when one person is "negative" and another is "positive", the best thing they can do is be separated.

Especially if the "negative" person goes in and out of the home.

This person, who perhaps now takes fewer precautions because they believe they are immune,

at work, socializing, etc.

What is the safest way to live with people who are positive for COVID-19 if it is not possible to isolate ourselves?

There are people who live in very small homes or who, for example, are in charge of caring for minors or the elderly.

Although it is really impossible for these people to self-isolate following the basic guidelines we discussed last week, they can also continue to take some helpful steps.

Although contagion in this case is very likely, they can

as far as possible.

The summary:

having overcome omicron in this sixth wave gives you an enviable immunity, especially if you are previously vaccinated since you will have what immunologists call "hybrid immunity", that is, more complete.

However, this does not make you "invincible".

As a precaution towards you and towards the rest, trying to isolate yourself from the people who are now infected around you will be the safest thing for everything
