Experts warn that "up to 65 million people can die" due to the outbreak of the virus. Respiratory Attack: The coronavirus attacks the airways, which can then cause infections such as Pneumonia or a common cold.

Also, between November 2002 and July 2003, there was an outbreak of respiratory symptoms, or illness ( SARS) in southern China, causing 8098 illnesses, resulting in deaths 774 people in 17 countries, mostly in China Mainland and Hong Kong (9.6%) mortality rates, according to the World Health Organization (WHO).

Since 2004, no SARS cases have been reported worldwide. But in recent days, a virus similar to SARS has killed dozens (56 as of morning) Sunday and infected nearly 2,000 people, mostly in mainland China. Known as the Novel Corona virus, written by the World Health Organization as the 2019-nCoV virus It is thought to have emerged from a market in Wuhan and has since spread throughout the world.

How does it kill people?
Coronavirus infection causes fever, cough, and cough. It then causes the patient to have shortness of breath or difficulty breathing. In severe cases, such as pneumonia – nCoV infection, according to the US Centers for Disease Control and Prevention (CDC). Can lead to gastrointestinal problems as well as kidney failure.

What epidemiologists say is that Chinese pathologists have compared the genes and proteins of the new virus, nCoV and SARS. The team then warned: "The nCoV presents a significant public health risk for transmission to humans." Wuhan nCoV – also known as the Corona virus (first discovered in Wuhan in December 2019) – SARS virus. For example, it has the ability to bind to proteins found on the surface of most human lung cells.

Also, it is important to note that the risk and survival of this type of infection or the human-to-human transmission are affected by the factor More, too. These include the immune response of the patient, the speed at which the virus can break down in the human lungs, and m Evolution can make the virus more vicious or infectious.

Signs and symptoms
The first symptoms are the same as the flu and may include fever, runny nose, muscle pain, nausea, cough, sore throat and other symptoms. Which is not specific. The most common symptom in all patients was fever above 38 ° C. It can also cause shortness of breath and pneumonia – either in direct pneumonia or secondary bacterial pneumonia. As with the SARS virus, the average attack time for this new coronavirus (2019-nCoV) is four to six days, though it may Short 1 day or 14 days long.

What Americans Say Health Professionals Predict in October that A New Virus May Kill 65 Millions a year, a warning issued three months before the outbreak China. "65 million – is the number of people who could be killed by a Corona virus in a year based on a model. "The computer is made by Dr. Eric Toner, a senior researcher at the Johns Hopkins Center for Health Security."

Experts at the prestigious Johns Hopkins Center for Health Security take epidemics on the software as part of Research last October. The disease took just 18 months to kill 65 million people around the world. Dr. Eric Toner, a senior researcher at Johns Hopkins, said he was not surprised when news of the outbreak began. The Corona virus in Wuhan first appeared in late December.
"I've been thinking for a long time that viruses are likely to be causing the virus," he told Business Insider. A new pandemic will be the coronavirus. "We know it's spreading from person to person, but we don't know the level." “The first impression is that it is lighter than SARS. So that's a confidence boost. And it's more contagious than SARS. "

How does the corona virus develop?
It is not clear. There have been reports that it was transmitted to people who ate bats or snakes infected with the virus. But there is no scientific evidence to back up this claim. It's the end of 2017 – 15 years after it was first discovered – Chinese scientists discovered the SAR virus through Intermediaries of vultures to bats live in caves in Yunnan province. But experts say the new virus is likely to be transmitted through contact or eating infected animals in Wuhan.
During the SARS outbreak, the virus killed about 1 in 10 people infected with the virus.

How to prevent infection
There is no vaccine to prevent coronavirus. Isolation is still the most effective way to prevent its spread.
Other preventive measures include:
– Wash your hands often
– Disinfection in the most affected areas
– Wear protective mask
Avoid contact with body fluids, especially patients
– Washing your own things with warm water and soap
– Keep the child at home – away from school
– Simple hygiene measures
Do not get near the town as much as possible to reduce your chances of contracting the virus.

How effective are public health interventions?
Many public health interventions are designed to try to control the spread of the disease, which is mainly spread through Air drops in the air.
These interventions include:
Detecting that you have the virus
– Keep infected persons separate
– Be alert to exposure and breathing air
– Use of personal protective equipment including masks, masks and gloves
– Virus detection processes are conducted at airports to monitor air travel to and from countries Affected.

Although no cases have been identified since 2004, the US Centers for Disease Control and Prevention remains Is working hard to guide the general population and respond quickly in case of recurrence of the virus.

Who affects them the most?
Corona virus is most contagious in critically ill patients, which usually occurs in the second week of the year Disease ៕
