The new sub-variant


Covid, Schillaci: “After 4-5 days stop in isolation for asymptomatic”

Tiago Gräf, a researcher at the Oswaldo Cruz Foundation, wrote on his profile Twitter that the new subvariant is making “resurrection of the pandemic in the Amazon. What happens there tends to repeat itself in other Brazilian states and could happen again”. However, the pandemic situation appears to be different from state to state. In Italy, for example, is moving towards a new change of rules for the quarantine of Covid-19 positives. “I think asymptomatic Covid-positive patients can be returned to normal activity after 4 or 5 days. Even those with mild symptoms can return earlier, after at least 24 hours of absence of fever, perhaps with some precautions such as a mask, to protect the most fragile”, declared the Minister of Health Orazio Schillaci, a guest on the evening of Wednesday 16 November of ‘Door to Door’.

The other opinions

Of a different opinion Fabrizio Pregliasco, professor at the University of Milan and medical director of the Irccs Galeazzi-Sant’Ambrogio hospital in the Lombard capital, who in a recent interview with ‘La Stampa’ reiterated the importance of keeping one’s guard up in Covid-19 comparisons now that winter is upon us. “There are upswings, the curves show us that there will be a wave, not a wave, and that it won’t be heavy. But you have to be prepared. And with seasonal flu it won’t be easy to distinguish between the two pathologies”. A recent study the result of joint work between the World Health Organization (WHO) and SeroTracker, a research group of 8 universities in Canada, the USA and the United Kingdom, has estimated that worldwide, between vaccines and infections, two thirds of population has specific antibodies against the Sars-CoV-2 coronavirus. According to the authors, the presence of antibodies against the virus in the world population reached 59.2% in September 2021. The results of the study were published in the pages of the specialized journal PLOS Medicines.
