Abstract: On December 31, 2019, a strange new pneumonia of unknown cause was reported to the Chinese WHO Country Office. COVID-19 is the name given by the World Health Organization (WHO) on February 11, 2020 for the disease caused by the novel coronavirus SARS-CoV-2. It started in Wuhan, China in late 2019 and has since spread worldwide. COVID-19 is an acronym that stands for coronavirus disease of 2019. Coronaviruses are common human and animal viruses. They were first discovered in domestic poultry in the 1930s. In animals, coronaviruses cause a range of respiratory, gastrointestinal, liver, and neurologic diseases. At this time, there are no specific vaccines or treatments for COVID-19. However, there are many ongoing clinical trials evaluating potential treatments. The best way to prevent and slow down transmission lies in being well informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol based rub frequently and not touching your face. It’s likely a vaccine will be developed for Covid-19, but the process is riddled with hurdles and may well take another nine to 12 months. Researchers are starting from scratch in the effort to create a vaccine against SARS-CoV-2. Even if one proves effective and safe in small tests — in rodents or humans — it will likely take months to scale production up because every vaccine requires a unique production technique. Till then, lock down at homes & adopting social distancing measures may reduce the spread of virus, but cannot eradicate the deadly pandemic and infact has a potential to unleash a second wave of outbreak. But few western countries have come under adverse criticism for their laxity in implementing the lock-down & consequent rapid rise in death toll. They were even alleged to rely on herd immunity and now paying a heavy price in severe fatalities. Given the complex & complicated situation created by pandemic Covid-19 creating havoc in the entire world and vaccine likely to be available in not less than a year, this paper advocates for awareness amongst the people for developing general immunity through food habits, physical exercises etc.
