A corona virus is one of
the numbers of virus that causes diseases in mammals and birds. In humans, the
viruses cause respiratory infections, including the common cold, fever, cough
and difficulty breathing in most patients. Rarer symptoms include dizziness,
nausea, vomiting and a runny nose. The name ‘corona virus’ is derived from the
Latin corona, meaning crown or halo which refers to the characteristic
appearance of the virus particles. In December 2019, an outbreak of the corona
virus began in Wuhan, China. The outbreak is ongoing as of February 2020. About
1500 people have already died and many others are affected daily.
Internationally, other countries sought to limit travel to and from the region
and implemented screening measures to detect those potentially carrying the
virus. Corona viruses can be transmitted between humans through respiratory
droplets that infected people expel when they breathe, cough or sneeze. A
typical surgical mask cannot block out the viral particles contained in these
droplets, but simple measures-such as washing our hands, disinfecting
frequently touched surfaces and objects and avoiding touching our face, eyes
and mouth-can greatly lower our risk of infection. There are no available
treatments for any human corona virus. Those who catch a common corona virus
usually recover on their own and can ease the process by taking pain and fever
medications, taking hot showers, drinking plenty of fluids and staying home to
rest.
