Coronaviruses: World is Coming Forward to Fight coronaviruses

China, Japan, the Republic of Korea, Thailand, the United States and other few countries are currently belligerent to contain a deadly coronavirus similar to the SAR widespread that originated in China in 2002. China has already reported 16,678 coronavirus cases and 479 deaths so far. The government has placed 13 cities under an effective obstruction with transportation restrictions, putting almost 41 million in virtual quarantine.

At the same time, the number of people in China who recover from the virus is increasing. On Tuesday, 4th-Feb,  262 people left hospitals across the country. The number of suspected cases has decreased for two days in a row. Authorities said they were tracking 3,971 suspected cases, compared to 5,173 cases the day before.

Hubei province has been the most affected by the virus and is home to the majority of deaths (479) and infections (16,678). Wuhan, in particular, has carried the worst part of deaths and infections.

The government said it has put 252,154 people under surveillance.

The city like Wuhan, etc. the place where the coronavirus originated, is in a state of severe cordon with all major flights and transport vehicles entering and leaving the city postponed in the future. While things are tense in China right now, the technology firms from different parts of China is coming to offer help. Chinese firms such as WeChat, Douyin (Chinese TikTok), Xiaomi, Meizu, and even Baidu have made efforts to educate and help fight the new coronavirus disease in China.

Kerala now confirms the third case of new coronavirus as on 4th-Feb. A total of 1,999 people, who have a history of travel from China and other affected countries, are under observation in Kerala, of which 75 are in isolation rooms of several hospitals.

What is a coronavirus?

what is Corona viruses?
what is Coronaviruses?

Coronaviruses belong to a large family of viruses that can cause respiratory syndromes such as the common cold, according to the Centers for Disease Control and Prevention (CDC). Most people get infected with coronaviruses at some time in their lives, but the symptoms are usually mild or moderate. In some cases, viruses can cause diseases of the lower respiratory tract, such as bronchitis and pneumonia.

Coronaviruses are common among animals all around the worldwide, but few of them are known to affect a human being. Rarely, coronaviruses can evolve and spread from animals to humans. This is what happened with the coronaviruses known as the Middle Eastern respiratory syndrome coronavirus (MERS-CoV) and the severe acute respiratory syndrome coronavirus (SARS-Cov), which are known to cause more severe symptoms.

How many people have been found infected with a new virus?

As of January 24, there are more than 830 (approx.) confirmed cases and 26 deaths related to the 2019-nCoV virus in China, according to The Washington Post.

How far has the virus spread?

The first cases of the pneumonia-like virus came into notice in Wuhan, China, on December 31, 2019. Since then, the virus has spread to other countries, such as Japan, the Republic of Korea, Thailand, the United States, and other few countries.

The first coronavirus in the US UU. It was confirmed on January 21 in a man in Washington state who had recently traveled to Wuhan. On January 24, authorities confirmed the second case in a woman from Chicago who had also recently traveled to the Chinese city. Both cases were hospitalized, but they did well, authorities said.

The CDC is also investigating more than 60 people in 22 states for possible infection with the new virus, authorities said Friday (January 24, 2020). Eleven of those people have been negative so far for the virus.

Where did the virus come from?

Since it (Corona Virus) first appeared in Wuhan, people who had visited a local seafood and animal market, authorities could only say that it probably hopped from an animal to a human. However, in a fresh study, researchers sequenced the 2019-nCoV genes (as it is now called the virus), and then compared it to the genetic sequences of more than 200 coronaviruses that infect several animals worldwide. Their results, detailed in the Journal of Medical Virology, suggested that 2019-nCoV probably originated in snakes.

As of now, scientists noted that two species of snakes that are common in southeast China where the outbreak originated: the krait of many bands (Bungarus multicinctus) and the Chinese cobra (Naja atra).

However, few experts have analyzed the study, saying it is unclear whether coronaviruses can infect snakes.

How did the virus (coronaviruses) hop from animals to humans?

It is known that some viruses can be transmitted to humans, and this coronavirus is one of those. But how? The study published in the Journal of Medical Virology, which reveals the likely snake host, also found that a change in one of the viral proteins in 2019-nCoV allows the virus to recognize and bind to receptors in certain host cells. This ability is a critical step to enter the cells, and the researchers said that the change in this particular protein may have helped the virus (coronavirus) jump to humans.

Can the virus (coronaviruses) spread between people?

Yes, in a few instances, according to the CDC, but the main mode of spread appears to be from animal to human. In regards to how the virus (coronavirus) would be contracted, the CDC says that coronaviruses found in human are more usually transmitted between a diseased person and others through:

—Air (coughs or sneeze viral particles);

—Nearby personal contact (touch or shake hands);

—An object or surface with viral particles (then touch your mouth, nose or eyes before washing your hands);

"And seldom because of fecal contamination."

How would coronaviruses virus cause a pandemic?

To cause a pandemic in humans, the coronavirus viruses must spread through three ways: proficiently contaminate humans, reproduce in humans, and then easily spread among humans. On current instance, the CDC says that this virus is transmitted among humans in a limited way, but they are still examining.

How does the virus (coronaviruses) compare to SARS and MERS?

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

The MERS, which was spread by touching infected camels or by consuming their milk or meat, was first informed in 2012 in Saudi Arabia and has been restricted primarily in the Arabian Peninsula, according to NPR. SARS was first reported in 2002 in southern China (not a single new case has been reported since 2004) and is believed to have spread from bats that infected civets. The new coronavirus was probably transmitted by touching or eating a diseased animal in Wuhan, China.

During the SARS outbreak, the virus killed about 1 in 10 people infected. The 2019-nCoV mortality rate is not yet known, although most of patients who have died from the infection have been older than 60 years and have had pre-existing conditions. However, more recently, a young and healthy man died in Wuhan, which raised concerns that the virus could be more dangerous than previously thought, according to The Washington Post.

What are the symptoms of the new coronavirus and how do you treat it?

Fever, cough and shortness of breath are a few symptoms of the new coronavirus include. Most symptoms are similar to those caused by SARS, according to a new study published in The Lancet.

Despite sharing some symptoms similar to SARS, "there are some important differences," such as the absence of upper respiratory symptoms such as a runny nose, sneezing and sore throat and intestinal symptoms such as diarrhea, which affected 20% to 25% of the SARS patients, lead author Bin Cao, of the China-Japan Friendship Hospital and Capital Medical University, both in Beijing, said in a statement.

As of now, there are no identified treatments for coronavirus infections and most infected people will recover on their own, according to the CDC. Therefore, treatment involves rest and medications to relieve symptoms. A humidifier or a hot shower can help relieve a sore throat and cough. If you are mildly ill, you should drink plenty of fluids and rest, but if you are worried about your symptoms, you should consult a healthcare provider, they wrote. (This is advice for all coronaviruses, not specifically targeting the new virus).

New coronavirus has no vaccine, but researchers from the US National Institutes of Health confirmed that they were in the preliminary stages of one's development. In addition, the pharmaceutical company Regeneron announced that it is in the early stages of developing a treatment for this virus, according to NBC News.

What is being done to stop the spread of the coronavirus?

According to the New York Times, the Chinese government has stopped most of the trips to and from Wuhan, as well as to 12 other close towns. This "blockade" distresses about 35 million people, the Times stated.

The main US airports carry out screenings/checks to ensure that incoming passengers are not infected. However, US officials said Friday (January 24) that they are currently examining the situation on an emergency basis.

What do we expect in the coming days?

By looking at what happened with the MERS and the SARS, some spread of the virus is likely to continue due to close contact between humans, according to the CDC. More cases are likely to be identified, possibly some in the US, in the next few days.

How can people protect themselves and others from coronaviruses or other viruses?

If you travel to Wuhan, you should avoid contact with sick people; avoid dead or live animals, animal markets or foods or products that come from animals such as raw meat, according to the CDC. One should wash their hands with soap and water for at least 20 seconds, as advised by the CDC. If you are diseased with the virus, you can take steps to avoid spreading it to others, such as separating yourself at home, avoiding yourself from other people in the house, wearing a face mask, covering your cough and sneezing and washing your hands, according to CDC.

People who traveled to Wuhan and became ill with cold, cough, fever or shortness of breath in the next two weeks should seek medical attention instantly and call ahead to inform the medical staff about their recent journey.
