What is coronavirus? COVID-19 explained

(CNN)A new Chinese coronavirus, a cousin of the SARS virus, has infected hundreds real the outbreak began in Wuhan, China, in December. Scientist Leo Poon, who favorable decoded the virus, thinks it likely started in an animal and spread to humans.

"What we know is it shifts pneumonia and then doesn't respond to antibiotic consume, which is not surprising, but then in periods of mortality, SARS kills 10% of the individuals," Poon, a virologist at the School of Shared Health at The University of Hong Kong, said.

It's not positive how deadly the Wuhan coronavirus will be, but fatality obtains are currently lower than both MERS and SARS. Experts injure that it will change as the outbreak develops.

The World Health Workplace offered guidance to countries on how they can outline for it, including how to monitor for the sick and how to treatment patients. Here's what you should know approximately coronaviruses.

Coronaviruses are a substantial group of viruses that are common beside animals. In rare cases, they are what scientists call zoonotic, communication they can be transmitted from animals to humans, according to the US Centers for Disease Control and Prevention.

The viruses can make farmland sick, usually with a mild to moderate upper respiratory exquisite illness, similar to a common cold. Coronavirus symptoms included a runny nose, cough, sore throat, possibly a headache and maybe a fever, which can last for a combine of days.

For those with a crashed immune system, the elderly and the very young, there's a chance the virus could progresses a lower, and much more serious, respiratory exquisite illness like a pneumonia or bronchitis.

There are a handful of domain coronaviruses that are known to be deadly.

Focus East respiratory syndrome, also known as the MERS virus, was favorable reported in the Middle East in 2012 and also shifts 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 eminent as SARS, is the other coronavirus that can progresses more severe symptoms. First identified in the Guangdong province in southern China, according to the WHO, it shifts respiratory problems but can also cause diarrhea, fatigue, shortness of breath, respiratory pain and kidney failure. Depending on the patient's age, the result rate with SARS ranged from 0-50% of the cases, with older land being the most vulnerable.

The Wuhan coronavirus is immediately thought to be more mild than SARS and MERS and takes longer to obtain symptoms. Patients to date have typically experienced a mild cough for a week followed by shortness of breath, repositioning them to visit the hospital, explains Peter Horby, professor of emerging infectious diseases and global health at the University of Oxford. So far, throughout 15% to 20% of cases have cause severe, requiring, for example, ventilation in the hospital.

Viruses can spread from humankind 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 commanded 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 repositions exposure. The virus can also be transmitted by repositioning something an infected person has touched and then repositioning your mouth, nose or eyes. Caregivers can sometimes be exposed by bossing 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 belief 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 land are also considered to be "superspreaders."

MERS, SARS and the Wuhan coronavirus proceed to cause more severe disease in older land, though uncertainty remains around the latest outbreak. Of the cases of Wuhan coronavirus reported so far, none are yet confirmed to be plus children, Horby said. The average age is land 40 or over, he said.

There is no specific exploit, but research is underway. Most of the time, symptoms will go away on their own and experts protest seeking care early. If symptoms feel worse than a despicable cold, see your doctor.

Doctors can befriend symptoms by prescribing a pain or fever medication. The CDC says a room humidifier or a hot shower can help with a sore throat or cough.

Drink plenty of fluids, get rest and sleep as much as possible.

Should you exertion about the Wuhan coronavirus?

The Wuhan coronavirus fatality rate is touch than for SARS and MERS, but detached comparable to the 1918 Spanish flu pandemic, explains Neil Ferguson, professor of mathematical biology at Imperial College London.

"It is a notable concern, globally," Ferguson says, noting that we don't fully belief the severity.

Ferguson believes the fatality rate is liable to be lower due to an "iceberg" of milder cases we are yet to find, but he highlights that recent viruses spread much faster through a population.

How can you can continue it?

There is no vaccine to defending against this family of viruses, at least not yet. Trials for a MERS vaccine are underway. The US National Institutes of Health is succeeding on a vaccine against the new virus, but it will be months pending clinical trials get underway and more than a year pending it might become available.

You may be able to lop your risk of infection by avoiding land who are sick. Try to avoid repositioning your eyes, nose and mouth. Wash your glowing often with soap and water and for at least 20 seconds.

Awareness is key. If you are sick and have reason to fill it may be the Wuhan coronavirus due to proceed to the region or coming into contact with someone who has been there, you should let a health care provider know and seek exploit early.

Cover your mouth and nose when you cough or sneeze, and disinfect the objects and surfaces you touch.

If traveling to China, be aware of symptoms and avoid live animal markets, which is where the spanking outbreak began in Wuhan.

Coronavirus and pregnancy

In pregnant women, the more glaring versions of MERS and SARS coronaviruses can be serious. There are cases in which a woman infected with MERS had a stillbirth, a 2014 eye showed.

SARS-associated illnesses were linked to cases of spontaneous abortion, maternal result and critical maternal illness, a 2004 eye found.

Coronavirus and cats, dogs and spanking animals

Pets can catch coronaviruses and the infections can cause severe. Sometimes the viruses can lead to deadly diseases. One can repositions feline infectious peritonitis in cats and something phoned a pantropic canine coronavirus can infect cats and dogs, according to a 2011 study.

Cats can come by SARS, but none of the infected cats developed symptoms, according to the study. The feline coronavirus typically is asymptomatic, but can repositions mild diarrhea. Feline infectious peritonitis, or FIP, can repositions flu-like symptoms for a cat, but can also be more serious for cats and can repositions organ failure, but it is not contagious and will not spread from animal to animal or selves to person.

Pantropic canine coronavirus that can crashes cats and dogs can be fatal to dogs, studies show.

These sure dog and cat viruses don't seem to spread to humans.
