What is Corona Virus?

Corona virus (coronavirus, abbreviated as CoV) is a large family of viruses consisting of many types of viruses. Various types of corona viruses can cause various diseases, ranging from common cold coughs to more dangerous ones such as severe acute respiratory syndrome (SARS) and Middle Eastern Mers respiratory syndrome.

On December 31, 2019, the WHO office in China was notified of a pneumonia case whose cause was unknown detected in the city of Wuhan, Hubei Province, China. Then on January 7, 2020 the Chinese authorities identified that the cause was a new corona virus (novel coronavirus).

On February 11, 2020, WHO gave a special name for the disease caused by the new corona virus, namely COVID-19 which stands for coronavirus disease 2019 (corona virus disease 2019). Later the new corona virus was also named SARS-CoV-2, short for severe acute respiratory coronavirus 2 syndrome.

The outbreak in Wuhan was linked to the large seafood market and live animal market there, given the way the corona virus spreads through animals. More and more patients have reportedly not visited animal markets, which shows that it is spread from person to person.

Not only in China, cases of virus infection have also been reported in Italy, South Korea, Singapore, Thailand, Japan, Malaysia, Australia, Germany, the United States, France, Indonesia, and many other countries (more than 100 countries). In Indonesia on March 2, 2020 the first positive case of COVID-19 was reported. And when this article was written, an investigation is underway to learn more about this virus.

How is the Corona Virus Spread?

Although the corona virus comes from animals, the way it spreads to humans is generally transmitted from infected people to other people at close range (about 6 feet or 180 cm).

What are the ways of transmitting corona virus from person to person? It is estimated that transmission can be through:

Air, through sneezing and coughing

Direct physical contact, for example through touch or shaking hands

Touching objects or surfaces that have been contaminated with the virus, then touching the mouth, nose, or eyes without washing hands

Fecal contamination (rare)

The corona virus is considered the most contagious when an infected person has shown symptoms. Therefore it is recommended to keep a distance of more than 1 meter and avoid direct contact with someone who has flu-like symptoms.

What are the symptoms of contracting the Corona virus?

Common types of corona viruses that affect humans, such as type 229E, NL63, OC43, and HKU1, usually can only cause mild to moderate upper respiratory tract diseases, such as common cold coughs. Most people have been infected with the virus. And the disease caused by the corona virus usually only lasts a short time.

What are the symptoms caused by corona virus infection that is common in humans? Here are some that often appear:

Runny nose

Headache

Cough

Sore throat

Fever

Feeling unwell

The corona virus in humans can sometimes cause lower respiratory tract diseases, such as pneumonia or bronchitis. But it is more often experienced by people who suffer from heart and blood vessel disease, people who have a weak immune system, infants, and the elderly.

Symptoms of Corona COVID-19 infection

For recent outbreaks of corona, COVID-19, it has been reported that people who have been infected experience varying degrees of symptom severity. There are no symptoms, only a few symptoms, so the symptoms are very severe. The following are the symptoms of COVID-19 corona infection that must be watched out for:

Fever

Cough

Hard to breathe

The Centers for Disease Control and Prevention Institute believes that these symptoms can appear within 2-14 days after a person has been exposed to the virus. This is based on what has been observed previously during the incubation period of the MERS-CoV virus

Other Symptoms of Corona Virus Infection

Two types of corona viruses in humans, MERS-CoV and SARS-CoV, are known to cause illnesses that have quite severe symptoms. What are the symptoms caused by the corona virus?

Symptoms of MERS-CoV infection usually consist of fever, coughing, and shortness of breath which often progress to pneumonia. About 3 or 4 out of every 10 patients who are reported to be infected with MERS-CoV die. The MERS case continues, especially in the countries of the Arabian Peninsula.

Whereas in SARS-CoV infection, the symptoms that are generally caused include fever, chills, and body aches that usually progress to pneumonia. Unlike MERS disease, no cases of SARS in humans have been reported anywhere in the world since 2004.

If you experience symptoms as above, you should immediately consult a doctor. Let him know if you have recently traveled to an area where COVID-19 is present or if you have met a positive COVID-19 person. And also tell your doctor if you have just arrived from a country in the Arabian Peninsula, considering that most cases of MERS-CoV infection occur there.

What are the diseases caused by the Corona Virus?

The corona virus consists of four main sub-groups, namely alpha, beta, gamma, and delta. The corona virus in humans was first identified in the mid 1960s. Until now, seven corona viruses have been identified that can cause disease in humans:

229E (corona alfa virus)

NL63 (corona alfa virus)

OC43 (corona beta virus)

HKU1 (corona beta virus)

MERS-CoV (corona beta virus that causes MERS disease)

SARS-CoV (corona beta virus that causes SARS)

The types of corona viruses that most often cause disease in humans are type 229E, NL63, OC43, and HKU1. What is the disease caused by the corona virus?

In general, the four types that cause mild to moderate upper respiratory tract infections. An example is the common cold cough sore. In more rare cases, all four types can also cause lower respiratory tract infections, such as bronchitis and pneumonia.

Sometimes the corona virus that infects animals can develop and attack humans so that it becomes a new type of corona virus in humans. Three examples of cases like this are SARS-CoV, MERS-CoV, and most recently SARS-CoV-2.

What is the disease caused by the three types of corona virus? SARS-CoV virus causes severe acute respiratory syndrome (SARS); MERS-CoV virus causes Middle Eastern respiratory syndrome (MERS); and the SARS-CoV-2 virus identified as a cause of pneumonia in the city of Wuhan, Hubei Province, China.

On Tuesday 11 February 2020, WHO gave a special name for the disease caused by the SARS-CoV-2 corona virus, namely COVID-19. This stands for coronavirus disease 2019.

Conclusion about Corona Virus

What is corona virus? The corona virus (coronavirus, abbreviated as CoV) is a large group of viruses that can cause a variety of diseases, ranging from common cold coughs to severe ones such as bronchitis, pneumonia, SARS disease, and MERS disease.

How is the corona virus spread? Corona virus in humans is generally transmitted from person to person.
