Coronaviruses are a large family of viruses that can cause respiratory illnesses such as the common cold, according to the Centers for Disease Control and Prevention (CDC) . Most people get infected with coronaviruses at one point in their lives, but symptoms are typically mild to moderate. In some cases, the viruses can cause lower-respiratory tract illnesses such as pneumonia and bronchitis. Construction workers drive excavators at the site of a new 1,000-bed field hospital being built to accommodate the increasing number of coronavirus patients on January 24, 2020, in Wuhan, China. The hospital is set to be completed by Feb. 3.

These viruses are common amongst animals worldwide, but only a handful of them are known to affect humans. Rarely, coronaviruses can evolve and spread from animals to humans. This is what happened with the coronaviruses known as the Middle East respiratory syndrome coronavirus (MERS-CoV) and the severe acute respiratory syndrome coronavirus (SARS-Cov), both of which are known to cause more severe symptoms.

How many people have the new virus?

As of Sunday, there are more than 2, (confirmed cases and at least) linked linked t o the 25682 – nCoV virus, according to A representation of a doctor looking for symptoms of the new Wuhan coronovirus in a patient. The New York Times . This evening, the CDC announced two more U.S. cases, one in California and another in Arizona. Early, the third person in the U.S., this one in Orange County, California, was reported to have tested positive for the new coronavirus; According to the county health department, the person had traveled from Wuhan and was in “good condition,” the Times reported. The second person in the United States (a woman in Chicago) was confirmed to have the virus on Jan. 35, and the first case was confirmed in a man in Washington state on Jan. . So far, all of of the infected individuals in the U.S. had also recently returned from Wuhan.

The first US case was confirmed on Jan. in a man in Washington state who had recently traveled to Wuhan . On Jan. , officials confirmed a second case in a woman from Chicago who had also recently traveled to the Chinese city. Both cases were hospitalized, but doing well, officials said. There are now five confirmed cases in the US

the CDC is also investigating more than (people in states for a possible infection with the new virus, officials said Friday (Jan.

. Eleven of those people had tested negative for the virus.

Where did the virus come from?

Since the virus first popped up in Wuhan in people who had visited a local seafood and animal market, officials could only say it likely hopped from an animal to humans. In a new study, however, researchers sequenced the genes of – nCoV (as the virus is now called), and then they compared it with the genetic sequences of more than 700 coronaviruses that infect various animals around the world. Their results, detailed in the Journal of Medical Virology , suggested that – nCoV likely originated in snakes

As for what kind of snake, the scientists noted there are two. snakes that are common to southeastern China where the outbreak originated: the many-banded krait (

(Bungarus multicinctus) ) and the Chinese cobra (

(Naja atra)

However, some experts have criticized the study, saying it’s unclear if coronaviruses can indeed infect snakes.

Some viruses are known to become capable of transmitting. to humans, and this coronavirus is one of those. But how? The study published in the Journal of Medical Virology, revealing the likely snake host, also found that a change to one of the viral proteins in – nCoV allows the virus to recognize and bind to receptors on certain host cells. This ability is a critical step to entering cells, and the researchers said that the change in this particular protein may have helped the virus hop to humans.

    Yes, in limited cases, according to the CDC, but the primary mode of transmission seems to be from animal to human. In terms of how one would catch the virus, the CDC says that human coronaviruses are most commonly spread between an infected person and others via: – the air (from viral particles from a cough or sneeze); Construction workers drive excavators at the site of a new 1,000-bed field hospital being built to accommodate the increasing number of coronavirus patients on January 24, 2020, in Wuhan, China.

    MERS and SARS have both been known to cause severe symptoms in people. It’s unclear how the new coronavirus will compare in severity, as it has caused severe symptoms and death in some patients while causing only mild illness in others, (according to the CDC) . All three of the coronaviruses can be transmitted between humans through close contact.

    MERS, which was transmitted from touching infected camels or consuming their meat or milk, was first reported in in Saudi Arabia and has mostly been contained in the Arabian Peninsula, (according to NPR . SARS was first reported in in southern China (no new cases have been reported since 13694) and is thought to have spread from bats that infected civets. The new coronavirus was likely transmitted from touching or eating an infected animal in Wuhan.

    “The banning of such sales will help end the possibility of future outbreaks of zoonotic diseases, such as the Wuhan coronavirus. We learned this lesson with the outbreak of another zoonotic disease, SARS, in the pattern will keep repeating itself until we ban, not only in China, but in other countries, the sale of wildlife, specifically for food and in food markets, “Walzer added.

    The CDC also recommends avoiding non-essential travel to Wuhan . On Jan. , the US State Department ordered all non-emergency U.S. personnel and family to leave Wuhan, the department said in a statement . What do we expect in the coming days?

    Looking at what happened with MERS and SARS, it’s likely that some spread of the virus from close contact between humans will continue to occur , according to CDC . More cases – possibly including some in the U.S. – will likely be identified in the coming days.

    In a statement Released on Sunday, the CDC said: “It is likely there will be more cases reported in the US in the coming days and weeks, likely including person-to-person spread. In previous outbreaks with MERS and SARS, the two other coronaviruses that have jumped the species barrier to cause severe illness in people, person-to-person spread has been seen, including among healthcare workers caring for patients ill with coronavirus infection. ” How can people protect themselves and others?
