What is Coronavirus | Coronavirus causes, prevention ...

What is corona:

  • Family of RNA virus in the Nidovirales order
  • Significant viral pathogens in human and animals
  • Corona- the prefix comes from the Latin for Crown 
  • Name for “Crown-like” appearance of virus

 Four classification

1)     Alfa
2)     Beta
3)     Gamma
4)     Delta
5)     Human coronavirus are alpha-and beta-coronavirus
  •  Medium-sized virus enveloping a positive standard RNA
  • Very large RNA genome

Hosts, Reservoirs and infected animals
  •  Infect birds and mammals
  • Bats are hosts to the largest number of viral genotypes of coronavirus
  • Epidemics can occur when viruses transmit from one species to another
  • Can cause mutations in proteins that allow the virus to bind to cells

  • Human coronaviruses are caused by respiratory and gastrointestinal tract infections
  • Estimated to account for 5-10 percent of all adult respiratory tract infection
  • GI symptoms including diarrhea

When mutations occur, coronaviruses can be a significant cause of human epidemics.

·        What is Coronavirus:
Coronavirus is a large family of the virus that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome(MERS-CoV), and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.
Coronaviruses are zoonotic, meaning they are transmitted between animals to people, detailed investigations found that SARS was transmitted from civet casts to humans and MERS from dromedary camels to humans.

Symptoms of Coronavirus:-
Dry cough
Runny nose
Sore throat
Breathing difficulties

The symptoms can lead to shortness of breaths where some patients will need hospital treatment.

Incubation Periods:
Novel Coronavirus: – 2-14 or 0-24 days
SARS: – 2-7 days. As long as 10 days
MERS: - 5 days (range 2-14 days)

To prevent the spread of COVID-19:
1)   Maintain a safe distance from anyone who is coughing or sneezing.
2)   Don’t touch your eyes, nose or mouth
3)   Cover your nose and mouth with when you cough of a sneeze
