The activities of the gym meanwhile continue. Based on the first checks, all the anti Covid regulations have been respected. Subscribers ask to be informed even if they are not direct contacts of the infected. They are very attentive to the rules, but they did not warn us of the outbreak – says Paolo, 40, just before entering the sports center -. Now ask for updates at the reception. While Alberto, 30 years old, does not break down for the ten positives: Zero risk does not exist.
Not the first time that the Delta variant has been found in Lombardy. In our experience, since January we have intercepted 12 cases – he says Fausto Baldanti, head of the molecular virology laboratory of the San Matteo Polyclinic in Pavia -. Among these, 11 were travelers returning from India and one was an “autochthonous” infection. All unvaccinated. These data were collected with the so-called active surveillance, which leads to more in-depth analyzes in the event of outbreaks or in particular situations.
Another tool to map the spread of the Delta virus is the survey promoted by the Higher Institute of Health once a month. Each Region is asked to analyze a certain number of samples taken randomly from the positives and to look for which variants are present. In the latest survey of May 18, Lombardy found six cases of B.1.617.1 / 2 (the abbreviations of the Indian virus), with an estimated prevalence of 2.5 percent. These are low numbers – says Baldanti -. And it is not surprising the infection in a vaccinee. At San Matteo out of 4,000 immunized, 33 were re-infected: all with an English variant, all without symptoms or with mild symptoms. In short, in the face of these situations it is wrong to let your guard down, but equally wrong to bandage your head in advance.
