FACTS YOU PROBABLY DIDN'T HAVE ABOUT CORONA-VIRUS (COVID-19)

By Femi Akinpelu Joseph

The deadly Coronavirus disease, also known as COVID-19 

broke out from Wuhan, China in late 2019, but became more 

pronounced since the start of 2020; several thousands of people across the world have been badly hit by this epidemic. 

Questions have been asked, speculations are being made, about where it originated from, how it can be contacted, and how to prevent it.

Below are useful information about COVID-19 and tips on how you can protect yourself and your family from getting infected.

The Coronavirus Outbreak - What do you need to know? 

Start here.

      What is a Coronavirus?

     It is a novel virus named for the crown-like spikes that protrude from its surface. The coronavirus can infect both animals and people, and can cause a range of respiratory illnesses from the common cold to more dangerous conditions like Severe Acute Respiratory Syndrome, or SARS.

    How contagious is the virus?
According to preliminary research, it seems moderately infectious, similar to SARS, and is possibly transmitted through the air. Scientists have estimated that each infected person could spread it to somewhere between 1.5 and 3.5 people without effective containment measures.

   Where has the virus spread?
The virus originated in Wuhan, China, and has sickened tens of thousands of people in China and at least two dozen other countries.

   How worried should I be?
While the virus is a serious public health concern, the risk to most people outside China remains very low, and seasonal flu is a more immediate threat.

   Who is working to contain the virus?
World Health Organization officials have praised China’s aggressive response to the virus by closing transportation, schools and markets. This week, a team of experts from the W.H.O. arrived in Beijing to offer assistance.

Coronavirus 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."

Who is affected?

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

Coronavirus treatment

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

Doctors can relieve 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.

Coronavirus and cats, dogs and other animals

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

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

Coronavirus and pregnancy

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

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

    What if I’m traveling?

The United States and Australia are temporarily denying entry to non-citizens who recently traveled to China and several airlines have canceled flights.

    How do I keep myself and others safe?

   Washing your hands frequently is the most important thing you can do, along with staying at home when you’re sick.
