INCUBATION and SYMPTOMS of the DELTA variantThe DELTA variant determined a new wave of CONTAGIONS. One summer, the second, with the nightmare of being infected and infecting, in the illusion that everything seemed to be over. But what do we know about the DELTA variant? How long does the incubation last?
What are the symptoms and after when do they emerge? What to do next a contact at risk and when to swab?

Compared to the original strain, in fact, the mutation has specificities which are clarified by Professor Pierangelo Clerici, president of the Italian Clinical Microbiologists Association and of the Italian Federation of Scientific Laboratory Societies, through the lines of the Huffingtonpost.

What are the incubation times for the Delta variant?

It depends on the person concerned. In the unvaccinated we have an incubation that is almost identical to that of the original strain and goes from 5 to 12 days. In patients vaccinated with a single dose, however, the incubation is extended by a few days. While with two doses the possibility of getting infected is reduced to 10-15%.

How long after the infection do the symptoms appear? Typically, between 7 and 10 days.What are the symptoms caused by the Delta variant? From what we have observed so far, the Delta variant has an onset characterized by flu-like symptoms: cold, sore throat, light cough. Later, headaches, loss of taste and smell may appear. This is a sequence that can vary depending on the patient, while the common element is the initial cold (a runny nose is typical). Those listed so far are trivial symptoms to which must be added those that could affect unvaccinated subjects, who remain at risk of severe breathing difficulties and a severe course of the disease.

So, as far as pathogenicity is concerned, the virus has not changed. Absolutely not. It is a disease which, if not treated carefully, can still lead to a serious course or death. I repeat that this is a risk that today primarily concerns unvaccinated people. Furthermore, with the Delta, the spreading capacity of the virus has increased and it is much easier to become infected.How long after a risk contact can a swab be carried out? As for the original strain, the minimum time remains 72 hours from contact. The ideal time, on the other hand, is 5 days apart. If the subject has recovered from Covid or received a dose of the vaccine, the time needed may be longer because viral replication is reduced. And it is even more so if the person has received two doses of the vaccine.

So it is useless to queue up the day after contact with a positive. Absolutely useless. To be detected by the diagnostic tool, the viral load must have time to develop. Swabing before 72 hours doesn’t make any sense. We are in the summer, it is vacation time. What are the recommendations for preventing contagion? The recommendations remain the same: mask in closed or crowded places, distance, hand hygiene. But the key is the vaccine, the best pro-active measure in the fight against any infectious disease. Covid included. Let us remember that diseases such as smallpox and polio have been practically defeated thanks to vaccination.

Is the Green Pass a right viaticum?

It is a tool that can incentivize people to get vaccinated and that can help us achieve the goal we all care about: no longer having serious illnesses and deaths caused by the virus. We need to keep in mind the human cost this pandemic has had and act accordingly.
