                            Essay on coronavirus

Introduction

A new disease first identified in Wuhan, China, in December 2019, and now called COVID-19, continues to spread, primarily in China but cases have also appeared in some two dozen other countries. Coronaviruses originate in animals — like camels, civets, and bats — and are usually not transmissible to humans. But occasionally a coronavirus mutates and can pass from animals to humans and then from human to human, as was the case with the SARS epidemic in the early 2000s. China's National Health Commission confirmed that 15 health care workers have become infected, indicating that the virus can spread from human to human.

Most, but not all, of the first known cases in December 2019 were traced to an animal market in the Chinese city of Wuhan and are believed to have come from contact with live animals that were infected. The market has since been closed. Wuhan is a major logistics and transportation hub. It lies about 500 miles west of Shanghai and is home to more than 11 million people.

2) There are two types of coronavirus.

1.SARS(server acute respiratory syndrome)

2.MERS(middle east respiratory syndrome)

According to the World Health Organization (WHO), coronaviruses are a family of viruses that cause illnesses ranging from the common cold to more severe diseases such as severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS).

These viruses were originally transmitted from animals to people. SARS, for instance, was transmitted from civet cats to humans while MERS moved to humans from a type of camel.

Several known coronaviruses are circulating in animals that have not yet infected humans.

The name coronavirus comes from the Latin word corona, meaning crown or halo. Under an electron microscope, the virus looks like it is surrounded by a solar corona.

The novel coronavirus, identified by Chinese authorities on January 7 and since named SARS-CoV-2, is a new strain that had not been previously identified in humans. Little is known about it, although human-to-human transmission has been confirmed.

A.what kind of disease is this(cause)?

The outbreak is caused by a coronavirus. Common human coronaviruses cause mild to moderate upper respiratory symptoms, including the common cold, fever, and dry cough. some people also experience fatigue, headaches, and less frequently, diarrhea.shortness of breath can develop about 5 days in while more severe types can cause pneumonia and death. The name for this kind of virus comes from the crown-like spikes it has on its surface — "corona" is Latin for "crown."It's only the third strain of coronavirus known to frequently cause severe symptoms in humans.

B. Who is at risk of becoming infected?

The World Health Organization's Emergency Committee on the coronavirus said in Jan. 22 news conference that nearly three-quarters of cases have been in people over age 40 and that "cases who died — many had significant underlying conditions" like cardiovascular disease and diabetes. But there are confirmed cases in otherwise healthy, young individuals.

C. How many countries are affected by coronavirus?

To date, at least 20 countries or places have confirmed cases. At least 430 other cases have been identified in places outside China, including the U.S., Australia, Canada, Finland, France, Germany, Japan, Malaysia, Nepal, the Philippines, Singapore, South Korea, Taiwan, Thailand, and Vietnam.

Fifteen U.S. cases have been reported to date. The first U.S. case was reported on Jan. 21, in a man who traveled to China and began experiencing symptoms a few days after returning home to Seattle on Jan. 15. The second case, a woman in Chicago, was confirmed Jan. 24. The sixth confirmed case, reported at the end of January, marked the first instance of human-to-human transmission of the disease in the U.S.; a woman who had recently traveled to China spread the virus to her husband when she returned to Chicago.

D. What is being done to stop it from spreading?

Scientists around the globe are racing to develop a vaccine but have warned it is not likely one will be available for mass distribution before 2021.

Meanwhile, a growing number of countries have introduced a series of sweeping measures to slow the spread of the coronavirus, including nationwide lockdown, bans on gatherings, closure of schools, restaurants, bars, and sports clubs, as well as issuing mandatory work-from-home decrees.  

International airlines have canceled flights the world over. Some countries have banned non-citizens from entering their territories, and several more have evacuated their citizens from abroad.
