No trace of either the Delta variant or the new and fearsome English variant Xe, and Omicron 2 overtakes on Omicron 1 with 65% of the cases of positive Covid recorded and attributable to this type of contagion. This is the picture of the situation relating to the sequencing carried out in the laboratories of the University Hospital of Cagliari.

"There are only a few cases of Omicron 1 subtype - explains the medical director of Aou Ferdinando Coghe - for the rest, the Covid cases are all linked to the two main variants. We are still awaiting the results of the sequencing carried out both in Cagliari and in Sassari from the Higher Institute of Health: we await the results very soon. This survey will provide a complete picture of the situation in Sardinia ".

The strength and speed of the infections are now mitigated by vaccinations: "The very rare cases of severe symptoms - explains Coghe - are also included in the statistics. Vaccination is fundamental, also because there is a considerable difference in resistance to the virus between the second and the third dose. In short, the third dose is essential to protect yourself better ".

Many cases, but also a lot of concern for symptoms that can be mistaken for Covid: "The flu is also circulating and for this reason we always recommend the flu vaccine. First, to protect yourself from the flu. Second, to reduce events and facilitate the diagnosis of doctors ", concludes the medical director of the Aou of Cagliari.
