Corona viruses are enveloped, spherical or pleomorphic, single stranded RNA particles. The name corona is given due to its crown like appearance produced by the club- shaped projections from the outer surface of the envelop.
Mode of transmission:
- Many patients in China reportedly had some link to seafood and animal market since the disease outbreak. This indicates the animal to human transmission.
- Growing number of patients and global detection of cases confirms person to person transmission. This can happen due to droplets infection from infected person during coughing and sneezing.
- Contaminated surface contact to mouth, nose and eyes.
Symptoms and complications:
Generally signs and symptoms of disease appear in 2 to 14 days of viral infection. Patients with infection are observed with respiratory symptoms like:
- Shortness of breath
- Pneumonia (chronic lower respiratory syndrome)
An outbreak of corona virus associated respiratory disease known as severe acute respiratory syndrome (SARS) occurred in 2002-2003. The outbreak began in November 2002 in the Guangdong province in South China where it caused many deaths.
There is no specific treatment for infection with corona virus. There is no vaccine for human corona viruses developed till date. Control measures such as isolation of patients, strict quarantine of infected individuals, screening of travelers are being practiced globally.
