Like many others out there, you would also probably have questions about the mighty Coronavirus and the one topping the list is about the spread of the virus. Currently, the Novel Coronavirus has been spreading rapidly across the globe, affecting 175 countries and claiming more than 21,000 lives. With the global pandemic showing no signs to stop, here’s a closer look at how the deadly virus spreads.

Think of all the frequently touched surfaces where germs can lurk: kitchen counters, bathroom counters, doorknobs, elevator buttons, the handle on the refrigerator, handrails on staircases. The list goes on and on.

As the initial cases of the disease were associated with direct exposure to the seafood sellers in China, the first presumption of the spread of the virus was thought to be a case of “animal-to-human transmission”. However, subsequent patients were not linked to the above mechanism. Hence, the experts concluded that the virus could also be transmitted through person-to-person contact, and patients having the disease symptoms are the most common source of the spread of the disease. The possibility of spread prior symptom developments seems to be rare but is possible. Also, evidence exists that infected patients not showing symptoms can also spread the virus. This fact indicates that practicing self-isolation is indeed the best way to control the epidemic.

As evident with other respiratory illnesses, the spread of the disease is thought to occur through
respiratory droplets from coughing and sneezing. Aerosol transmission is also possible in case of closed spaces. The latter spread, however, mainly occurs to family members, healthcare workers, and other proximal contacts.

Data also indicates that cases of COVID 19 double every week in the epidemic. Thus average, each patient spreads the disease to an additional 2.2 individuals.
