Coronavirus & Covid-19: Updates, Symptoms and Risk Factors

Overview of Corona Virus

The first case of coronavirus was discovered during the 1930s when domestic chickens were affected with acute respiratory infections caused by the Infectious Bronchitis Virus. Human Coronavirus cases were first registered during the 1960s in the countries of the United Kingdom and the United States of America. They used two different standard techniques to isolate the people who are affected by the Coronavirus

Depending on the severity of the disease and how far they spread, doctors classified the coronaviruses into different types. 

Currently, doctors have identified seven types of viruses that can affect humans.

Types of coronaviruses: 

  • 229E (Alpha Coronavirus)
  • NL63 (Alpha Coronavirus)
  • OC43 (Beta Coronavirus)
  • HKU1 (Beta Coronavirus)
  • SARS (Severe Acute Respiratory Syndrome)
  • MERS (Middle East Respiratory Syndrome)

In 2019 new kind of virus was identified as SARS-CoV-2, which causes the disease COVID-19.

COVID-19

Coronaviruses are a group of viruses that can affect the respiratory system of birds and humans that causes the common cold, dry throat, dry cough, and sinus infections. All varieties of coronaviruses are not dangerous but viruses like Severe acute respiratory syndrome(SARS), and Middle East respiratory syndrome(MERS) are deadly. 

In December 2019, the World Health Organization identified a new type of coronavirus known as SARS-CoV-2 after the disease outbreak in China. It causes a disease called COVID-19. Later in March 2020, due to the quick spread of the disease to many countries globally, the World Health Organization announced the COVID-19 a pandemic.

Millions of people are affected by new coronavirus across the world. The United States of America has registered the highest number of cases that are affected by the new coronavirus. The coronavirus death toll is increasing day by day globally.

Virus is also transmitted through the objects or metals surfaces because the virus can live for several hours and days too depending on the materials.
