CURRENT VIRUS - COVID 19
The corona virus emerged in only December last year, but already the world is dealing with a pandemic of the virus and the disease it causes - Covid-19.
With this outbreak of fatal Corona Virus Disease, known as COVID -19, it is significant to acknowledge how the whole world can combat itself. WHO (World Health Organization), says, "Persons plagued with COVID-19 simply cannot kill this fatal virus by the spraying of chlorine and alcohol made sanitizers all over their bodies".
For most, the disease is mild, but most people die. Its speeding very fast in India too.
There is an urgent need for simple, fast and sensitive devices to collect, eliminate and deactivate viruses from air, to rapidly detect and prevent outbreaks and spread of infectious diseases. Each year, infectious diseases cause millions of deaths around the world and many of the most common infectious pathogens are spread by droplets or aerosols caused by cough, sneeze, vomiting etc. Knowledge of aerosol transmission mechanisms are limited for most pathogens, although spread by air is an important transmission route for many pathogens including viruses.
