coronavirus: All about causes, symptoms, risks, advice

The most recently discovered coronavirus is due to the coronavirus disease COVID-19.

In December 2019, Coronavirus (COVID-19) was first notified in Wuhan, China.

The unique coronavirus, identified by Chinese authorities on January 7 and by the name Covid-19, is a new strain not previously identified in humans. An outbreak of coronavirus (officially known as COVID-19) in China has killed more than 3,285 people and infected over 95,481 worldwide. The virus has spread to more than 80 countries including India.

In February, the World Health Organization (WHO) named the unique coronavirus “COVID-19”. “CO” stands “corona”, “VI” for “virus”, and “D” for “disease”, while “19” was for the year since the outbreak was first identified on 31 December.



Little is known about this, although human-to-human transmission has been confirmed.

Most coronaviruses are harmless. They can usually cause mild to moderate respiratory tract diseases like the common cold. Most people will become infected with these viruses at some point in their lives.

What is Coronavirus?

The name Coronavirus arrives from the Latin word ”corona”, which means crown or halo. So these viruses appear as crown-shaped when viewed under an electron microscope.

Coronavirus is a large family of viruses that can cause disease in animals or humans.

In humans, many coronaviruses are thought to cause respiratory infections ranging from the common cold to more serious illnesses such as the Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS).

A detailed investigation found that SARS was transported from civet cats to humans and MERS to dromedary camels to humans. Many known coronaviruses are roaming in animals that have not yet infected humans.

The death rate is about 10 percent for people with SARS and 30 percent for people with MERS variant.

What are the causes?

The human coronavirus is transmitted from the most infected person through others:

  • Air from coughing and sneezing.
  • Personal contact, such as touching or shaking hands.
  • Touching a thing(s) or surface with the virus on it, then touching your mouth, nose, or eyes before washing hands.

This is why it is important to live more than 1 meter (3 feet) from a sick person.

People more possible to be affected by a coronavirus including people with a weakened immune system, cardiopulmonary disease, infants, and older adults.

What are the common signs and symptoms?

Coronavirus can make people ill with mild to moderate upper respiratory tract disease, similar to a common cold.

Symptoms can range from mild illness to pneumonia. Some people will recover easily, and others may get sick very quickly.

Some common signs and symptoms of infection include:

  • Respiratory symptoms,
  • Fever,
  • Cough,
  • Shortness of breath and shortness of breath,
  • A general feeling of being unwell,
  • Running nose,
  • Sore throat,
  • Headache.

If a person is suffering from lower respiratory tract diseases like pneumonia or bronchitis, they should seek professional health immediately.

What is the risk of coronavirus?

In further critical cases, the infection can cause pneumonia, severe acute respiratory syndrome, kidney failure, and even death.

Most cases of coronavirus (COVID-19) are in Wuhan city of Hubei province, China.

Those who have the highest risk of getting the COVID-19 are:

  • Recently occurred in cities and areas affected by the coronavirus,
  • In intimate touch with someone who has a confirmed case of coronavirus.

While we are still learning that COVID-2019 affects people, the elderly, and those who already have a medical condition (such as high blood pressure, heart disease, lung disease, cancer or diabetes), compared to others In this disease develops more frequently.

Basic protective steps/advice against new coronaviruses

There is no cure for coronavirus, but medical care can treat most symptoms. Antibiotics do not work on viruses.

Be aware of the latest information on the COVID-19 outbreak available on the WHO website and through your national and local public health authority.

If you have detected coronavirus, isolate yourself in your home. Heed of your health and protect others by doing the following:

Clean your hands regularly and thoroughly with an alcohol-based hand or wash them with soap and water. Washing your hands with soap and water or rubbing alcohol-based hands uses the virus that can occur on your hands.

Maintain a distance between yourself and anyone who is coughing or sneezing at a distance of at least 1 meter (3 feet). When someone coughs or sneezes, they sprinkle small liquid droplets through their nose or mouth that may contain the virus. If you are very close, you can breathe in a cough, including the COVID-19 virus if the person coughing has the disease.

Avoid touching the eyes, nose, and mouth, hands touch many surfaces and can pick up viruses. Once infected/contaminated, hands can transfer the virus to your eyes, nose, or mouth. From there, the virus can enter your body and cause you to sick.

The virus is spread by droplets. By following good respiratory hygiene, you protect people around you from viruses like cold, flu and COVID-19.

This means covering your mouth and nose along with your bent elbow or tissue when you cough or sneeze. Then dispose of the used tissue immediately.
