A coronavirus is a group of viruses that cause disease in mammals and birds. In humans, they cause respiratory tract infections, which are mostly less fatal but sometimes fatal. Coronaviruses in cows and pigs are caused by diarrhea and diseases of the upper respiratory tract in chickens.

​

There is no vaccine or antiviral available for their prevention. Washing hands with soap is the best way to avoid it because the outer layer of the coronavirus is made up of proteins or oily lipids, which the soapy water breaks down. After this, the strain of the virus weakens.

Coronavirus Family

Coronaviruses have spread from time to time in human populations and cause respiratory infections in adults and children. They are more powerful, mainly in winter and early spring. So far, seven viruses of the Coronavirus family have been detected, details of which are as follows:

​

HCOV-229-E

Human coronavirus 229-E (HCOV-229-E) is a species of coronavirus, which infects humans and bats. This infectious virus is a single-stranded RNA—the virus, which enters the cells of its humans via the APN receptor. HCOV-229-E is transmitted through small vomiting and respiration. Symptoms range from a cold to a high fever such as pneumonia and bronchiolitis. 

​

HCOV-NL-63

HCOV-NL-63 is the alpha coronavirus. It was identified in late 2004 in a seven-month-old baby with bronchiolitis in the Netherlands. Later its association with many diseases in the world has come to the fore. These diseases include respiratory tract infections, group, and bronchiolitis. The virus is mainly found in young children, the elderly, and patients with acute respiratory disease. According to a study in Amsterdam, about 4.7% of common respiratory diseases have the presence of

HCOV-NL-63.

 

HCOV-OC-43

Along with HCOV-229-E, HCOV-OC-43 is also a common cold causative virus. This virus thrives in respiratory tract infections, including pneumonia in infants. Elderly and people with poor immunity, such as those undergoing chemotherapy and suffering from HIV-AIDS, are also more vulnerable. It is due to this virus when there is cold in the winter season.

 

HCOV-HKU-1

Acsiovi-Ackeyu -1, for the first time in January 2005, was identified in a 71-year-old man in Hong Kong, which is suffering from acute respiratory problems. Radiologically bilateral pneumonia was confirmed therein. During this time, this man had returned from Shenzhen, China.

​

SARS

SARS (Severe Acute Respiratory Syndrome), an ancestor of the Coronavirus family, was first found in China in 2003. It came from bats into humans. Due to this, about 650 people were killed in China and Hong Kong in 2003. Investigations revealed that the virus came from bats in humans.

​

MERSV

MERSV-COV (Middle East Respiratory Syndrome Virus) was discovered in 2012 in Saudi Arabia in Middle-East countries. This virus is an ancestor of the coronavirus family. So far, more than 800 people have died in Middle-East countries due to MERSV-CoV. This virus came to humans through camels.
