essay on what is corona virus and how does it spread and from where it came from
Answers
The 2019 novel coronavirus has the potential to be a global pandemic. Health officials say it originated in a market in Wuhan, China that sold live and dead wild animals that people ate for food, improved health and vitality and a number of other purposes. The virus has now been detected in Australia, Canada, Finland, France, India, Italy, Japan, Nepal, Russia, Singapore, Spain, Taiwan, Thailand, Vietnam, the United States and over a dozen other countries.
Health Officials Being Proactive
The good news is health officials around the world are being proactive in working to stop the virus from spreading. They have identified and broadcast the symptoms of the illness and have begun to quarantine people with the illness to prevent them from passing it on to others. Beginning Sunday, February 2, American citizens, permanent residents, as well as their immediate family members who have been to China’s Hubei province recently or had contact with people who had, must undergo a two-week mandatory quarantine period to ensure they are not infected with the 2019-nCOV virus.
A Two Week Incubation Period
One of the issues that has contributed to the spread of what health officials are calling the 2019-nCOV virus is its two week incubation period. During this time, a person may have the virus, display no symptoms of it, but can still spread it to others. This makes it difficult for people to know who has the virus and when they should take actions to protect themselves from becoming infected. This has created an extra sense of concern that the virus could quietly continue to spread.
Symptoms Of The Illness
People infected with the 2019 novel coronavirus begin to experience mild cold or flu-like symptoms in two to four days. Although the symptoms can vary from one person to the next, they typically include sneezing, coughing, runny nose, fatigue, sore throat and fever.
Wash Hands Regularly
According to healthcare experts one of the simplest things people can do to protect themselves from the 2019-nCoV virus is to wash their hands regularly with soap and water after making contact with people who could potentially have it. They recommend washing hands for at least 20 seconds before touching your eyes, nose, mouth or food.
Treating The Virus
Currently there’s no cure for the 2019-nCOV virus. Common treatments that have proven to be somewhat effective in controlling the symptoms include taking over-the-counter medication, drinking lots of water, getting adequate rest, avoiding overexertion, not smoking, staying away from smoky areas and using clean mist vaporizers or humidifiers.
Taking medications like acetaminophen, ibuprofen and naproxen can help to reduce the pain and fever associated with the illness.
What Are Coronaviruses
Coronaviruses are a group of viruses which typically tend to affect human and other mammal’s respiratory tract and their guts. The viruses are closely associated with infections like pneumonia, the common cold and conditions like severe acute respiratory syndrome(SARS) and Middle East Respiratory Syndrome(MERS).
Origin Of The Coronavirus
In 1937, coronaviruses were first identified as an infectious bronchitis virus with which birds suffered that could devastate poultry stocks. Today, the viruses are the cause of the common cold in 15% to 30% of all cases. In the past 70 years, researchers have found camels, cattle, cats, dogs, horses, mice, pigs, rats and turkeys that were infected with coronaviruses.

Explanation:
whats is corona virus?
corona viruses are a large group of viruses that are common among animals. In rare cases, they are what scientists call zoonotic, meaning they can be transmitted from animals to humans, according to the US Centers for Disease Control and Prevention.
Corona virus symptoms
The viruses can make people sick, usually with a mild to moderate upper respiratory tract illness, similar to a common cold. Coronavirus symptoms include a runny nose, cough, sore throat, possibly a headache and maybe a fever, which can last for a couple of days.
For those with a weakened immune system, the elderly and the very young, there's a chance the virus could cause a lower, and much more serious, respiratory tract illness like a pneumonia or bronchitis.
There are a handful of human coronaviruses that are known to be deadly.
Middle East respiratory syndrome, also known as the MERS virus, was first reported in the Middle East in 2012 and also causes respiratory problems, but those symptoms are much more severe. Three to four out of every 10 patients infected with MERS died, according to the CDC.
Severe acute respiratory syndrome, also known as SARS, is the other coronavirus that can cause more severe symptoms. First identified in the Guangdong province in southern China, according to the WHO, it causes respiratory problems but can also cause diarrhea, fatigue, shortness of breath, respiratory distress and kidney failure. Depending on the patient's age, the death rate with SARS ranged from 0-50% of the cases, with older people being the most vulnerable.
The Wuhan coronavirus is currently thought to be more mild than SARS and MERS and takes longer to develop symptoms. Patients to date have typically experienced a mild cough for a week followed by shortness of breath, causing them to visit the hospital, explains Peter Horby, professor of emerging infectious diseases and global health at the University of Oxford. So far, around 15% to 20% of cases have become severe, requiring, for example, ventilation in the hospital.
How it spreads
Viruses can spread from human contact with animals. Scientists think MERS started in camels, according to the WHO. With SARS, scientists suspected civet cats were to blame. Officials do not yet know what animal may have caused the current outbreak in Wuhan.
When it comes to human-to-human transmission of the viruses, often it happens when someone comes into contact with an infected person's secretions, such as droplets in a cough.
Depending on how virulent the virus is, a cough, sneeze or handshake could cause exposure. The virus can also be transmitted by touching something an infected person has touched and then touching your mouth, nose or eyes. Caregivers can sometimes be exposed by handling a patient's waste, according to the CDC.
Human-to-human transmission has been confirmed for the Wuhan coronavirus, but experts are now trying to understand who is transmitting it most, who is at most risk and whether transmission is occurring mostly in hospitals or in the community. SARS and MERS were largely transmitted inside hospitals, Horby said. Some people are also considered to be "superspreaders."
it came from
A new Chinese coronavirus, a cousin of the SARS virus, has infected hundreds since the outbreak began in Wuhan, China, in December. Scientist Leo Poon, who first decoded the virus, thinks it likely started in an animal and spread to humans.
