1. The new rules for isolating positives

The Spallanzani Institute, at the forefront of Covid treatment, has sent an opinion to the Minister of Health for the new rules on the isolation of Covid positivesproposing a change of course for the asymptomatic.

The current rules provide for 5-day home isolation for asymptomatic people or at least 2 days without symptoms for the other positives, with a negative swab on the way out, or 14 days without undergoing any swab. The experts of the scientific center said that Italy can align itself with other countries that have drastically reduced the quarantine period. Spallanzani has proposed a change in the rules to the Ministry of Health.

For asymptomatic people isolation of 5 days from positivity, without the need for another negative test. As for people with mild symptoms, isolation up to 5 five days after the onset of symptoms, if without fever for 24 hours. However, the Institute recommends caution in this case. “Especially in this phase, where there may be overlap with seasonal flu, it would be advisable in the following five days, if you do not have a negative test, to prudently use a mask, in case of contact with fragile people – notes the Institute – The scientific community today considers self-tests an accurate and suitable tool for documenting the end of the infection”. Meanwhile, a report from the Istituto Superiore di Sanità speaks of an increase in cases between health personnel and children.

2. The more you get infected, the more complications can increase

By now we know that those who have contracted the virus are not fully protected due to the diversification of Covid in many variations. But there is the general idea that those who have fallen ill and are vaccinated have developed a sort of super immunity. This thesis was denied by a study conducted by a group of researchers at the University of Washingtonpublished in the scientific journal natures. From the analysis of a large amount of data, such as the medical records of the infected, it emerged that with each new contact, the chances of experiencing complications increase. Study coordinator Epidemiologist Ziyad Al-Aly explains the study findings as follows: ‘Our research shows that contracting the virus a second, third or fourth time contributes to increased health risks in the acute phase, first 30 days after infection, and in the following months, i.e. in Long Covid”. Each infection seems to increase the risk of hospitalization, disorders affecting the lungs, heart, brain, blood, musculoskeletal and gastrointestinal systems, and even death. Reinfection would also contribute to diabetes, kidney disease and mental health problems.

3. When we can talk about returning to normal

The data of the last few weeks indicate a drop in infections and good news also comes from abroad. In China after almost three years of zero tolerance and very harsh restrictions, the government has announced a relaxation of some measures to stem the contagion, starting with the reduction of quarantine upon arrival in the country, which goes from ten to eight days. However, to say that we are out of the tunnel is premature and scientists advise caution. For the virologist Massimo Clementi, professor emeritus of the Vita-Salute San Raffaele University in Milan, it will be possible to speak of a reversal of the course of the pandemic when “for at least two months these regression data on infections will be consolidated. Then we can say that this infection is becoming endemic.” This means that it will reappear every winter together with the other viruses of the respiratory system, but it will no longer be scary.

For the scientist there is also a another indication of the return to normality which is the reappearance of the flu and the syncytial virus. For two winters, the flu disappeared, as the dominant virus was Covid. Now the regression of the pandemic has brought back viruses that have always characterized the winter period.
