"Stay home if you are sick; get tested and contact your doctor for assistance; get vaccinated, especially if you are part of a risk group; ventilate rooms; wear a mask when in the presence of others." These are the recommendations of the World Health Organization in response to the increase in Covid cases recorded in recent weeks at all latitudes.

The surge was also recorded here: according to the ministry update, in the week just ended Cagliari and the metropolitan city recorded the highest incidence in Italy, 140 infections per hundred thousand inhabitants .

"A peak was expected on August 15th, due to the large movement of people, the arrival of many tourists, the large influxes in closed environments such as airports: situations that increase contacts and the spread of a virus that has never disappeared, also because there is no type of measure that can contain the phenomenon ", explains Ferdinando Coghe , director of the Clinical Chemical Analysis and Microbiology Laboratory of the AOU of Cagliari.

Virologist Francesco Broccolo, from the University of Salento, intervenes: "Those who are dying of Covid are now people over 90, but most of them are hospitalized in ordinary wards, not in intensive care . Many of the patients over 90 do not show acute events or serious clinical symptoms that justify hospitalization in intensive care, but this does not mean that they are not at risk of an unfavorable evolution of the disease", observes the doctor.

On the “explosive” situation in the emergency rooms, where clearly many patients with Covid also arrive («occasionally infected people who generally come for other reasons») and sometimes have to wait even days before being admitted, Dr. Coghe underlines that at the moment «there is a hyper demand, an exaggerated request for assistance that comes from the territory, which determines a state of suffering. As far as we are concerned, we have done everything we could, even by hiring staff, but unfortunately if the patients double or triple, with a controlled number of beds, even if we try to add a few, we cannot do much more».
