The summer wave of contagion does not stop, even if the peak seems to approach. There Omicron sub-variant 5 continues to cause a sharp increase in cases in Italy, so much so that the Ministry of Health has authorized the administration of booster dose of the vaccine for the over 60s and the frail of all ages right away.
After the go-ahead from the EMA came the ministerial circular authorizing the administration of the vaccine 120 days after the first recall or the last infection. Meanwhile it does not stop the wave of contagions from Omicroneven if the data of the Monday bulletin – as always – certify a low number of positive swabs: they are 37 thousand, in any case slightly up compared to the previous week.
Now it is the worrying anomalies concerning the positivity to Covid: the onset of symptoms does not always match one swab positivity and for this reason the risk of infected people not being in isolation is much higher than in the past. But what are the symptoms and what is the incubation period del virus? How long does positivity last and what are the dangers associated with the failure to detect Covid? Let’s go into detail.
Omicron Symptoms 5
The first certainty about Omicron 5 is that it is very contagious, but the symptoms don’t change that much from the past. They are less severe than those seen with the Delta variant, especially since the thick infection does not affect the lungs. THE symptoms however, they are very similar: high fever (even higher than with the other Omicron sub-variants), sore throat, runny nose, tiredness, muscle pain, loss of smell and taste (even if only in a few cases), headache and even an abnormal symptom such as pain in the joints and knees.
Despite the high contagiousness, Omicron 5 appears to cause fewer hospitalizations, so much so that part of the patients in the Covid wards are positive but are hospitalized for other reasons. This, however, is not enough to avoid the increase in the employment rate in the departments Covid medical area throughout Italy.
How long do the symptoms last and when do we become negativized
Symptoms usually last for a few days: the time span goes from two to five. The duration is usually shorter when symptoms are milder. Also the period of positivity it is reduced compared to the Delta variant: as a rule, it is now negative within seven days, if not less in some cases.
Omicron 5 incubation times
The incubation times have greatly shortened with Omicron 5 compared to the Delta variant and the original virus. By now it takes between two and three days from contact with the positive to have the first symptoms. There are, however, cases of incubation with longer times, even up to two weeks. In the first phase of contagion, however, i tampons are believed to be less reliable and hence a big problem, so experts recommend repeating the tests after a couple of days.
The Omicron 5 anomaly: beware of symptoms and tampons
Precisely that of tampons is a not insignificant problem, because it can happen that even having the symptoms you are likely to be negative, only to find that they are positive when they are disappearing. A big problem especially for the spread of the virus, because in this way there is the risk of having a negative swab (with symptoms) and not respecting the isolation, thus being able to infect other people, even the most fragile ones.
The negative test cases at the beginning of the symptoms are now more and more common with Omicron 5. This makes it even more complicated to trace and try to isolate who is positive, who in these cases may not know they are positive, perhaps thinking that the symptoms are related to everything. other, especially when they are mild.
