United States.- A recent study indicates that the new coronavirus began to circulate earlier than was thought in the city of New York, It should be remembered that this city in the United States is one of the regions that has registered the most cases in the world and its first case was officially registered on March 1 and that same month a figure of 1.7 million infected was reached in the city and mortality from the virus was approaching 1 percent.
This conclusion was drawn after researchers analyzed nearly 10,700 plasma samples that were drawn between 9 February and on July 5, 2020 in which evidence of past SARS-CoV-2 infections was sought.

“We now know that there were many asymptomatic and mild to moderate cases that are likely to go undetected,” said Dr. Emilia Mia Sordillo, senior study author, a physician treating infectious diseases at the Icahn School of Medicine and the Sistema Mount Sinai Health Center in New York City.
The experiment sought to evaluate the samples in two groups who were admitted to emergency rooms on Mount Sinai who had moderate to severe symptoms as the New York City outbreak progressed. The second group included nearly 6,600 samples from patients seen for regular office visits or for treatment, and was seen as a reflection of infection rates in the general city population.
The study showed that the rate of infections during the first wave in New York was high, but not close to what was needed to pay for group immunity. The lead author of the study indicated that knowing the detailed dynamics of seroprevalence shown in this study is important to model seroprevalence in other parts of the country.
Currently the United States is the country in the world most affected by the coronavirus pandemic with a total accumulated cases of 9 million 893 thousand 570 and 327 thousand 34 accumulated deaths. So far there is no treatment or cure for the coronavirus, which is why a healthy distance is still recommended to avoid infections.
Worldwide, 9 million 893 thousand 570 accumulated cases of coronavirus have been registered with 237 thousand 034 cases of accumulated deaths.
