Coronaviruses are types of viruses that typically affect the respiratory tract of mammals, including humans. They are associated with the common cold, pneumonia, and severe acute respiratory syndrome (SARS) and can also affect the gut.
Coronaviruses are named for the crown-like spikes on their surface. There are four main sub-groupings of coronaviruses, known as alpha, beta, gamma, and delta. Human coronaviruses were first identified in the mid-1960s. The seven coronaviruses that can infect people are:
Common human coronaviruses
- 229E (alpha coronavirus)
- NL63 (alpha coronavirus)
- OC43 (beta coronavirus)
- HKU1 (beta coronavirus)
Other human coronaviruses
- MERS-CoV (the beta coronavirus that causes Middle East Respiratory Syndrome, or MERS)
- SARS-CoV (the beta coronavirus that causes severe acute respiratory syndrome, or SARS)
- 2019 Novel Coronavirus (2019-nCoV)
People around the world commonly get infected with human coronaviruses 229E, NL63, OC43, and HKU1. Sometimes coronaviruses that infect animals can evolve and make people sick and become a new human coronavirus. Three recent examples of this are 2019-nCoV, SARS-CoV, and MERS-CoV.
More than 440 cases of Coronavirus (2019-nCoV) are now confirmed in China and the death toll from the outbreak has risen to 9 people, according to China’s Deputy Health Commissioner. The first case in the United States was announced on January 21, 2020. The Centers for Disease Control and Prevention (CDC) is closely monitoring an outbreak caused by a novel (new) coronavirus (2019-nCoV) first identified in Wuhan, Hubei Province, China. Chinese authorities identified the new coronavirus, which has resulted in close to 300 confirmed cases in China, including cases outside Wuhan, with additional cases being identified in a growing number of countries internationally.
Currently, CDC is investigating this new virus but there are some ways by which you can protect & prevent yourself from Coronavirus. Listed below are the steps from the Centers for Disease Control & Prevention.
How to protect yourself ?
There are currently no vaccines available to protect you against human coronavirus infection. You may be able to reduce your risk of infection by doing the following
- wash your hands often with soap and water for at least 20 seconds
- avoid touching your eyes, nose, or mouth with unwashed hands
- avoid close contact with people who are sick
How to protect others
If you have cold-like symptoms, you can help protect others by doing the following
- stay home while you are sick
- avoid close contact with others
- cover your mouth and nose with a tissue when you cough or sneeze, then throw the tissue in the trash and wash your hands
- clean and disinfect objects and surfaces
