Coronaviruses (CoV) are a group of disease causing viruses commonly affected by mammals and birds. In humans, these viruses can cause mild respiratory infections which includes the common cold but it can get lethal with rarer forms like
Middle East Respiratory Syndrome (MERS-CoV)
Severe Acute Respiratory Syndrome (SARS-CoV).
A new novel coronavirus (nCoV) has not been previously identified in humans.
Coronavirus is transmitted between people and animals, thus making it zoonotic. They may cause diarrhea in pigs and cows, while an upper respiratory disease in chickens.
No antiviral drugs or vaccines are approved for its treatment.
In India, the first case of the novel coronavirus is reported in Kerala. A student at Wuhan University is stable and in isolation at a hospital, a statement from the Health Ministry said.
The Chinese govt has clamped down on the central Chinese city of Wuhan, the epicenter of the deadly coronavirus that has claimed over 170 lives so far and infected thousands. The reach of the virus has been reported from as far as the United States. The outbreak happened last month.
Common signs of infection:
- Respiratory symptoms,
- Breathing difficulties.
Severe cases include:
- Acute respiratory syndrome,
- Kidney failure,
- Even death 💀
To prevent infection spread include:
- covering mouth,
- regular hand washing,
- covering nose when coughing and sneezing,
- cooking meat and eggs thoroughly,
- Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.
Coronaviruses are viruses in the family Coronaviridae in the subfamily Orthocoronavirinae, in the order Nidovirales.
Coronaviruses are enveloped viruses with a positive-sense single-stranded RNA genome and with a nucleocapsid of helical symmetry. The genomic size of coronaviruses ranges from approximately 26 to 32 kilobases, the largest for an RNA virus.
“Coronavirus” is derived from the Latin corona, meaning crown or halo, which refers to the characteristic appearance of the virus particles (virions): they have a fringe reminiscent of a royal crown or of the solar corona.
