Coronavirus in the United States was in November 2019: if this is true

Several common posts in Facebook saying that people in the United States, probably, has contracted the coronavirus even in the fall of 2019, but then no one suspected that boleznb caused by a new infection. About it writes USA Today.

“You were sick in November or December, and it lasted from 10 to 14 days with a very severe cough, which is not passed? If you can answer “Yes”, then you may have a was of coronavirus. There were no tests, and flu test will come back negative. Then it’s just called a severe upper respiratory infection,” — said in posts.

Many of the currently circulating message includes the wearer’s Facebook, Donna Lee Collier.

Bonnie Powell of Waynesboro, Georgia, copied the status and received more than 230 posts. She said that is her opinion, not necessarily scientific proof. But she said she heard from friends about the disease late last year.

“In our area was a very dangerous flu season, and many of my friends had a negative test result for flu,” she wrote in a post on Facebook.

Coronavirus, probably originated in Nov

The researchers attribute the origin of the virus with the market of live animals in Wuhan, China. The world health organization first received reports of the outbreak on December 31, but the virus originated in China more than a month earlier. A study published in early March by researchers from ETH Zurich, points to the emergence of the virus in the first half of November.

Rumors about the origin of the new coronavirus has spread around the world. The theory that the virus originated in Chinese laboratories, or that it originated outside of China and was transferred to the US army, not supported by the data, according to medical experts. It is believed that the virus is of animal origin: probably from bats.

January 21, the Centers for control and prevention of diseases of United States (SVS) announced the first case of the novel coronavirus in the United States in a person who recently returned to Washington from Wuhan. Since then, the United States surpassed China and Italy, becoming the most infected country in the world, according to the tracker at the Johns Hopkins University.

The symptoms of novel coronavirus infection include fever, cough and shortness of breath. According to reports, the manifestations range from mild symptoms to severe symptoms and death.

Could the coronavirus to be in the US until January?

Experts say it is likely that the coronavirus came to the U.S. from China before the first case officially recorded in January, but to be sure, it is necessary to conduct additional testing.

“We’ve heard about some flu-like illnesses in December and January, which was a bit unusual, says Dr. Louis Ostroski, Professor of infectious diseases at the Medical school McGovern at UTHealth in Houston. But we can solve this mystery, when we really begin to test for antibodies, not just to detect the virus”.

Ostroski said it will include the analysis of blood samples in December and January to learn whether the virus is already in the United States.

Dr. Georges Benjamin, Executive Director, American public health Association, said that, in his opinion, when the researchers will conduct more tests, they will probably find that the disease was in the US earlier than expected.

“I believe that at the end of it all, when we look back we will probably find that the disease was here earlier than we thought,” said he.

However, Benjamin said that “plausible but unlikely” that the coronavirus was in the US in November and December. According to him, if the disease was in the US before the end of the year, it would be associated with travel from China, and probably would not have received wide distribution.

Dr. Josh Petri, associate Professor-researcher in the School of public health, University of Michigan, said it’s important to remember that many existing viruses can cause severe symptoms in the upper respiratory tract and these viruses have been circulating at the end of last year. Among them were influenza B, the intensity of which increased around November and December, as well as RSV (respiratory syncytial virus) and influenza A.

He said that perhaps the cases were associated with travel, but agree that they are probably not widespread.

“Every year influenza surveillance, and therefore, if we observed greater activity of the coronavirus at the time — even if I couldn’t test it — some signals surveillance would have shown,” he said.

Whether the fact that the person had COVID-19, to protect it from re-infection? It is also still under investigation. Ostroski said, in General terms, other coronaviruses do cause the creation of immunity.

Published in the New York Times article about the studies of the antibodies carried out at the present time, described the response to the question of immunity as “a qualified “Yes”, with some significant unknown.” Dr. Vineet D. Menachery, a virologist from the medical Department of the University of Texas in Galveston, said that infected people may have immunity from one to two years, and the duration of this period is difficult to predict.

Need more information

At the moment, experts say that those who have had a cough or other symptoms of upper respiratory tract infection likely not infected with coronavirus.

But it is also possible that some cases went to the United States before the first case was in January. Experts say that to get the exact pattern required additional testing and research.
