There were limited COVID-19 says cases in the United States during most of January report New CDC

In its most recent Morbidity and Mortality Weekly Report, researchers at the US Centers for Disease Control (CDC) say it is for most of the month of January and that SARS-CoV-2, the virus that causes have been limited in US cases COVID-19, the disease began a short distance at the end of the month and dissemination in February. These results suggest that a test program and aggressive recognition could be a part of the spread of SARS-CoV-2 have softened, allowing public health officials to contain the infection reliably. In a briefing with reporters paintings, however, said CDC Director Dr. Robert Redfield, that the number of cases of COVID-19 in late January was so low that to find them, even if the tests were released as ” would be a search for a needle in a haystack. “Redfield says that existing respiratory diseases by collecting systems” have eyes on this epidemic really. ” the US government in the early screening passengers from hot spots of infection in China in mid-January before the arrivals from the country as a whole to stop a few weeks later. But COVID-19 developed by the CDC tests have been delayed because of early contamination problems that are behind public health officials were designed to identify those who were infected Dr. Jay Butler, deputy director of CDC infectious diseases;. Responsible COVID-19, the Agency’s reply, and a co-author of the recent paper, highlights four support lines of the idea proof that COVID-19 was before the end of the J in the US But only to spread January. First, he says, the data from the emergency room from 14 districts across the country do not show an increase in some of the characteristic symptoms of the disease, such as fever, cough and shortness of breath, to February 28. This data, in the national syndromic surveillance program includes 4,000 health facilities in 47 states that the information related to the emergency room. The 14 counties the agency focused on those that contain cases of early community-based and ended with probably one of the first regions must have spread the disease. Second, the genetic sequences of the virus SARS-CoV-2 in the United States and elsewhere also suggest that the virus is not widespread in the United States by the end of January. Based on these sequences, which serve as a kind of genetic fingerprint of different strains and the virus traced lines, the researchers believe that both China a virus descent was introduced in late January, when the first confirmed US was identified case in Washington state; Other cases in the area identified shared similar genetic signatures. This conclusion is supported by a new set of tests on samples of nasal passages of people in the Seattle area, where the first case was identified US crop. They came from people who have provided samples in the study of the influence Seattle to monitor for flu prevalence and available from the nose and the back have been involved in the gorge, the recovery could be analyzed for SARS-CoV-2. More than 5,000 samples of this study of people with respiratory symptoms between January 1 to February 20 “did not show COVID-19 infection,” collected, says Butler. “This does not mean that the virus does not mean it was present everywhere in the community. It just means that when it was circulated, it was at such a low level that could not even be detected when to test 5,000 samples of people with respiratory diseases.” In third, the CDC team also such influence provides monitoring of data from five other location in the United States at this time and did not find the samples that tested positive for COVID-19 Finally, Butler put three first cases of COVID -19 in people who had traveled to China or other areas where the disease is flourishing, were exposed to the virus in their community suggests. This in turn means that it is likely that the virus was present in the US, but not widely used in early January. Two people in Santa Clara County, Cal. He died of COVID-19 infection on January 31, and between 13 and 17 February are. Post-mortem analysis confirmed COVID-19 in both, and the study of their infection and disease progression is not yet complete. Since the virus takes about five days for the symptoms unfold and begin due, it is likely that these people have been infected several weeks before he died before he had reports of clusters of cases. Looking back on how COVID-19 to catch on in the United States did not earn only academically, says Butler. “To understand more about the dynamics of the spread in the community, it is an important part of planning as we move forward in [the disease] control.”
