Omicron 5. Doubts, perplexities and questions about the etiology of Omicron variant that – because of his extreme contagiousness – continues to keep the attention of the experts high. In particular the request that recurs on several occasions on the part of the citizens is this: why despite the negative result of the swab I have the symptoms of Covid?
This is in fact the phenomenon encountered by a large number of people, let us now try to clarify the situation and above all to understand the reasons for it.

Omicron 5: the reasons behind the time lag
The situation mentioned above highlights the massive presence of what can be defined as one time lag between the negativity of the swab and the presence of symptoms. In fact, many people despite the negative outcome of the swab have, show, all the symptoms of Covid and are positivized only at a later time, that is when the symptoms begin to fade, to be milder.
This difference is an aspect to be considered and not to be taken lightly as it could slow down the diagnosis positive cases, with all the consequences and risks it entails. The situation, not just around the corner, has in fact and legitimately captured the attention of the Scientific Community which has taken steps to understand the causes.
The hypotheses of the Order of Doctors
To explain it is federation of the Order of Doctors in the address book Doctor, but is that true? Here they are advanced some hypotheses which account for the phenomenon just described. First one of the first explanations is that the negativity of the tampon even in the presence of Covid symptoms is dictated by the immune system. That is to say that today, two years after the start of the pandemic, the immune system is more reactive, activating faster than before to fight the virus.
The role of variants
Secondly, on the other hand, another of the most accredited hypotheses is that of new variants. In particular referring to the recent Omicron 5 mutation, it presents a different diffusion mechanism inside the organism which in this case is characterized by a lower accumulation of viral particles in the nose. This latter aspect contributes to fueling the cases of false negatives.
Homemade tampons
Finally, a final hypothesis that according to experts could explain the time difference existing between the negativity to the swab and the presence of symptoms is represented by the swab do-it-yourself. In this case the false negatives would be attributable to gods mistakes carried out during the home tampon process, such as a careless collection of biological material.
