Snakes probably aren’t behind China’s coronavirus outbreak …

Editor’s note: This is a developing story that has been updated since it was first published. HealthLine will continue to update this article when there is new information.

coronavirus originated in Wuhan, China, puzzling experts search for the source. Since the virus is considered a novel, it is a type of virus that has never been observed before.

coronaviruses are named for the crown as their shape, and the first in the mid-1960s. The virus usually causes respiratory illnesses such as the common cold.

At first, many of them infected with work or shopping at wholesale seafood market in Wuhan, China, which is also sold new live animals and slaughtered.

This is why experts suspect it crossed over to humans from animal hosts.

According to Chinese researchers at the South China Agricultural University have analyzed more than 1,000 samples of wild animals metagenome to find pangolin, pangolin species, is the most likely host between of a new coronavirus.

“They found that the strain of coronavirus sequence was assembled from metagenomes is 99 percent identical to the coronavirus-infected people in the recent outbreaks,” state media said.

Shen Yongyi, a professor with the university and a member of the research team, told the news agency that although previous studies found the new coronavirus originated bats, animals hibernate in winter, so it is unlikely that they caused the current outbreak.

However, the actual study has not been published. So far, the university just issued.

“Evidence of the potential involvement of pangolin in the outbreak has not been published, but by the university press release,” said Professor, PhD, Head of the Department of Veterinary Medicine, University of Cambridge in. “It is not scientific evidence; investigation of animal reservoirs are very important, but the results should then be published for international supervision to enable proper consideration. Quite reported the detection of viral RNA with sequence similarity of> 99 percent is not enough. “

A study January 30, in The Lancet, found strong evidence that the bat is where the infection originated.

According to the authors of the study, the infection could still have been transmitted to humans through animal intermediaries. Previous research theorized that he went through the snake before it is passed on to humans.

“Despite our phylogenetic analysis showed that bats may be the original host of the virus, the animals are sold in the seafood market in Wuhan power represents an intermediate host facilitate the emergence of the virus in humans,” write the study authors.

Bats have an unfortunate history through a potentially deadly pathogen to the human host.

2017 article described how the virus identifies a single population of horseshoe bats keep the virus strain with all the genetic building blocks of the SARS virus that jumped to humans in 2002. The worldwide outbreak killed nearly 800 people.

Research on Emerging Infectious disease confirms that many bats Africa is also a reservoir of the Ebola virus is very dangerous

“Every time a species jump appears, each time the virus jumps from one species to another -. that species would not initially have good d develop immunity against the virus. As time passed our ability to fight the rise of new virus, “Director of Infection Prevention and Control at Mount Sinai in New York, said HealthLine.

This is not the first time coronavirus pathogen has crossed from the host animal. Ebola, severe acute respiratory syndrome (SARS), and the Middle East acute respiratory syndrome (mer) is the latest example.

“There are a lot of different theories, but what seems to be a consistent approach in our findings in all of them is that there may be a species jump,” said Javaid.

He explained that there are seven coronavirus that infects humans, including new viruses.

“The four of them actually cause the common cold and they have been with us for a very long time, maybe a few more will be identified with time, and they are largely confined to the human population. SARS, and especially mer, considered jumping from other species to humans and this new virus is another leap that is possible. “

A recent New England Journal of Medicine (NEJM) published in January that “readiness improvements needed in animal markets and other animal facilities, while the likely source of emerging viruses is under investigation. ”

“We already have the virus structure. I think it should be emphasized how quickly the scientific and medical community are now directed to respond to these things, “said, a pediatric infectious disease attending physician at Children’s Hospital Boston and Senior Medical Director, Karius Inc.

Ahmed asserted that every time we go through an outbreak of this type, there are systems in place of previous events. “So we get the structure, we get in a virus isolation; they are already talking about the development of vaccines. Little is getting genetic information, sequencing will be important. By sequencing the different strains, you can assess populations and transmission dynamics of what strain came from, because the order binding the virus to its source. “

People in China are desperately trying to get their hands on face masks, trust that wearing one would protect them from exposure to droplets sneezed or coughed by those infected with the virus Wuhan.

“there has been no public call for the public to start wearing a mask. Some people may take steps of their own, “said Ahmed.

Ahmed said the United States Centers for Disease Control and Prevention (CDC) is recommending good hygiene, and tell people to stay home from work if they’re sick. “And if they sneeze or cough to do it properly, like coughing into their sleeve, not into your hands, because if you cough into your hands, you can spread around it.”

He stressed the importance of clean hands and use alcohol-based hand sanitizer when soap and water are not available. Also, to avoid close contact with people who are sick and for routine surface disinfection.

“The other thing is to avoid touching your eyes, or mouth, because they are areas where you can directly transmit pathogens into your body,” said Ahmed.

If you have COVID-19 or suspect you have a virus that causes COVID-19, you should seek medical care.

You have several options to get medical treatment, including being seen by your primary health care provider. CDC recommends calling your provider first so that they can take the necessary steps to prepare for your visit and others to protect from possible exposure to the virus that causes COVID-19.

Some health care providers also offer through your smartphone or laptop, so you may not need to leave your home for an initial assessment.

If you do not have a primary care provider, you can use this tool to find local office in your area.

If you have a medical emergency, call 911. Tell the operator that you have COVID-19 or suspected exposure to the virus that causes it. If possible, wear a face mask before emergency medical services arrived

“This is a system that is not perfect but, you know, we have to balance – in free liberal countries, obviously there are some trade-offs. Countries that exercise control over their populations have a more rigorous way to control this sort of thing. You have to balance their interests; public health, but also the freedom of the individual and freedom, “said Ahmed.

He concluded, “It is difficult to predict at this time, but I think that people need to exercise some degree of caution and awareness that this could be a big problem, but we do not know it yet. We must prepare ourselves in terms of disease and response to epidemics and the government clearly gearing their efforts and definitely in the hospital on the basis of our hospital get ready for those kinds of efforts. “

The new virus was first identified in Wuhan, China, is a type known as a coronavirus. As with previous outbreaks of SARS and mer, probably jumped to humans from animals. Researchers have found evidence that may be derived bat, but then the second beast like a snake or other types of pangolin called pangolin may have been transmitted to humans.

Although the virus can have severe effects on people now, experts say that these cansdecreases over time as our immune system to adapt.

The effort to contain the virus are not perfect, but they are the best health officials can implement without infringing excessively on the rights of the people.

experts stressed that it was too early to say what will happen, but the government and health facilities get ready to deal with emergencies.
