Covid, in the USA infections are spreading again in the western and southern states

The summer wave of Covid in the United States it started earlier than expected. In fact, for about two weeks now, federal data have indicated that infections have started to increase again, particularly in the southern and western states of the Union, where cases are considered “high.”

As the Centers for Disease Control and Prevention explain, for the first time in months there is no state or territory in the United States where Sars-Cov2 infections have decreased in the last week. There are now two variants of the virus that are worrying the CDC: KP.3 and LB.1, both with a sharply increasing trend in infections.

Confirmed infections due to the KP.3 mutation now represent a third of cases compared to 25% just two weeks ago. The LB.1 variant is responsible for 17.5% of new diagnoses. According to scientists, LB.1 would have a higher contagion capacity and appears destined to take over even KP.3.

According to Dr. Robert Hopkins, medical director of the National Foundation for Infectious Diseases, “the virus tends to replicate well and stay alive in a warm, humid environment. The South and West of the United States are humid and hot right now.” The summer surge has become a constant in recent years but experts warn that the coronavirus can still be quite unpredictable. “I think it’s still a little It’s too early to say what the standard pattern will be,” Hopkins said. “A large portion of the population has been exposed to the virus, the peaks have been a little less high, and we’ve tended to see a summer surge and a winter surge. But whether this model will continue, whether it will become a widespread disease throughout the year or whether the virus will remain in a particular period is still too early to say.”
