" We have no evidence that the virus has changed but the epidemiological situation has changed. Thanks to the preventive measures, the virus now circulates in another population. It is not the virus that attacks young people, but we have made the elderly safe, hospitals, the most fragile population and therefore the virus find space to circulate now at a low intensity in a healthier population. This is why it seems weakened, it is the tail of the epidemic which is the effect of the preventive measures " . This was said by Pierluigi Lopalco, epidemiologist of the University of Pisa and responsible for coordinating the epidemiological emergencies of the Puglia Region, speaking on the Centocittà program on Rai Radio 1. "The virus hasn't changed, it's the same", only that at this moment its circulation involves "younger and asymptomatic subjects. This explains the lowest contagiousness". This was said by Professor Pierluigi Lopalco, head of the Apulian task force for the Coronavirus emergency, on RadioNorba. "The summer - he continued - we have to spend it with serenity, the virus circulates much less. In Puglia the cases detected in these days are all imported cases, people returning to Puglia. However, we avoid going all in the same place, we don't crowd places ".
On the possible second wave of infections in the autumn, he explains: "We are already doing active surveillance to prevent the virus from spreading in the population, we are increasing the number of swabs. Now we are doing between 2,000 and 3,000 a day, but we could do more This preparation will be important in late summer. "
" For the Immuni App this is a moment of break-in so it is important, if you receive a message, you must keep it on your mobile phone, possibly take a screenshot, in order to check each time if it is true positive or an error of interpretation ". Pierluigi Lopalco said so, commenting on the story of the 63-year-old from Bari, who was put in isolation after a message from the App but then tested negative, "In the lady's case we are heartbroken - he added -. The lady was angry, she deleted the message and uninstalled the App, so we could not verify what message it received. Because we had other reports of this kind: in one case, Android message mistaken for a message of contact; in another case it was a fake positive, so a technical error. "
