What is Coronavirus Disease or COVID-19? Causes, Symptoms, Precautions & Cure

Viruses have always posed a health risk to humans and animals since time immemorial. There are many known and unknown viruses that threaten the health and well being of human life around the world. The Coronavirus disease (COVID-19) is the latest type of virus that was discovered in Wuhan, China and is creating a global pandemic across several countries.

Advancement in the field of medicine has helped to identify and reduce the spread of the virus and also create antiviral drugs and medicines to boost immunity. But Antibiotics have a limited effect on viruses.

A virus is basically a biological agent that can reproduce inside the cells of the living hosts. When infected by a virus the host cell produces thousands of identical copies of the original virus at a very fast rate. Viruses do not have cells that divide like most living things. New viruses are assembled in the infected host cell.

Unlike other infectious agents, viruses contain genes that give them the ability to mutate and evolve. There are over 5,000 species of viruses on the earth. Viruses are among the smallest infectious agents and most of them can be only seen under an electron microscope. Their sizes range from 20 to 300 nanometer.

What is Coronavirus?

What is Corona virus?

The coronaviruses were first identified in the early 1960s. We do not have a clear idea about where they came from but they get their name from their crown-like shape.

  • Sometimes a coronavirus can infect both humans and animals.
  • Generally, most of the coronaviruses spread the same way as other cold-causing viruses do.
  • It happens when infected people cough or sneeze or touch an infected person’s hands or face.
  • Even touching the doorknobs touched by an infected person can cause the spreading of the virus.
  • Most people get some type of coronavirus infection at least once in their life. In the USA they are common in the fall and winter.
  • The coronavirus causes upper respiratory infection. The coronavirus symptoms include stuffy nose, cough, and sore throat.

You can treat some of them with rest and over the counter medication. It can also cause middle ear infection in children.

Information about the Coronavirus (COVID-19)

A coronavirus is a kind of common virus that causes an infection in your nose, sinuses or the upper throat. Basically, most coronaviruses are not dangerous. But some of them can cause serious health issues.

In 2003, there was a SARs (Severe Acute Respiratory Syndrome) breakout and 774 people died. About 858 people had died from the MERS (Middle East respiratory syndrome in 2012 in Saudi Arabia and a few countries in the middle east and Asia. MERs and SARs are types of coronavirus. The present COVID-19 pandemic is creating chaos across the globe. The coronavirus effect on the global population and economy has been devastating.

Information about the Coronavirus (COVID19)

Some Quick Facts:

  • The Coronavirus disease (COVID-19) originated in Wuhan, the largest city in central China, with a population of over 11 million people.
  • Germany, Japan, and Taiwan have reported the first cases in patients who did not personally visit China but still contracted the virus from someone else who had visited Wuhan, China.
  • The is a probability of the infection passed on to humans from bats since they are the natural reservoirs of many such viruses including the SARs and MERs
  • “Bats are host to a significantly higher proportion of zoonoses than all other mammalian orders.” Zoonoses are diseases that spill over from animals to humans.
  • The coronavirus spread to most countries has been very quick.

What Causes Coronavirus?

The Coronavirus disease is a virus that has been identified as the main cause of COVID-19 outbreak of respiratory illness.

  • Initially, there was some link to an animal market and a large seafood market that suggested that the coronavirus spread from animal to human. 
  • But since a growing number of patients without exposure to the animal market contracted the disease it has been indicating a person to person transmission. 
  • The first case was reported in early December 2019.
  • It is still unclear how many ways this virus can spread between people. 
  • The WHO (World Health Organization) identified it as a new type of virus and named it COVID-19.

Some Common Coronavirus (COVID-19) Symptoms

The most common COVID-19 symptoms are similar to any other upper respiratory infection. It includes

  • Runny Nose
  • Dry Cough
  • Sore Throat 
  • Shortness Of Breath
  • Fever

Coronavirus Symptoms

Sometimes it is not clear whether a person is affected by the coronavirus or the cold-causing virus rhinovirus. It is possible to do some lab tests including nose and throat cultures and blood work to perform coronavirus diagnosis and determine whether the cold was caused by a coronavirus.

Coronavirus (COVID19) Symptoms

If a coronavirus infection spreads to the lower respiratory tract then it can cause pneumonia. This happens especially in older people or people with a weaker immune system. The COVID-19 vaccine may take time to develop.

How to Prevent Coronavirus (COVID-19) Transmission And Reduce Exposure to the Virus?

The WHO (World Health Organisation) has released a standard recommendation for the general public in order to reduce exposure and prevent coronavirus transmission. These include general hand and respiratory hygiene and safe food practices.

Coronavirus Prevention

  • Wash hands thoroughly with soap and water for at least 20 seconds or use an alcohol-based hand sanitizer with above 60% alcohol content.
  • When coughing and sneezing, cover your mouth and nose with flexed elbow or tissue. Then throw the tissue away immediately and wash hands.
  • Avoid close contact with anyone who has a fever and cough. Wear a good facial coronavirus mask covering your nose and mouth.
  • If you have a fever, cough and difficulty breathing seek good medical care early and share previous travel history with your healthcare provider.
  • When visiting live markets in areas currently experiencing cases of a COVID-19, avoid direct unprotected contact with live animals and surfaces in contact with animals.
  • The consumption of raw or undercooked animal products should be avoided. Raw meat, milk, eggs or animal organs should be handled with care, to avoid cross-contamination with uncooked foods, as per good food safety practices.

Treatment for Coronavirus (COVID-19)

The antiviral treatment and coronavirus cure is currently not specified. People who are infected with this virus need supportive care to help them relieve the coronavirus symptoms. If the case is severe the treatment should include care to support the vital organs.

CoronaVirus treament

The people who think they have been exposed to the coronavirus influenza should immediately seek the coronavirus remedy and contact the healthcare experts. Most people with common human coronavirus illness will recover on their own. Certain steps can be taken to relieve the coronavirus symptoms.

  • Take some pain and fever medications (Caution: Do Not give Aspirin to children)
  • Use a room humidifier or take a hot shower to ease the sore throat and the cough
  • Drink lots of warm water and take adequate rest to recover
  • Visit a healthcare expert if symptoms worsen or aggravate


We are facing some unprecedented challenges in tackling such new and emerging diseases. Wuhan in China has been the epicentre of the current COVID-19 outbreak. The city has been isolated and has come to a standstill.

CoronaVirus Conclusion

Scientists are working round the clock to find effective COVID-19 cure and medicines. They also need to create the right vaccines to prevent such viral coronavirus outbreaks. Society needs to gear up and maintain good hygiene at home and public places and avoid risky situations and unhygienic places.

“Prevention is Better than Cure”

A collective and focused effort by global governments and the public will help to contain the COVID-19 epidemic spread. We need to spread more awareness and important information among people and also dispel the myths surrounding such diseases. People need to come together forgetting their differences to fight this COVID-19 pandemic affecting humanity.
