A review on the COVID-19: Facts and current situation

COVID-19 has affected our life drastically. National lockdown, Social distancing, and working from home are the new normal. Many developed countries with their advanced medical facilities find it challenging to tackle the pandemic situation. The second wave of covid-19 is associated with unexpectedly higher rates of mortality relative to the first wave. The breakout of mutant strains that make the virus highly transmissible across the country has led to new challenges for scientists and researchers alike in developing vaccines and finding a cure for the disease. While several Biopharma companies and Research Centre like Pfizer-BioNTech, Moderna, AstraZeneca, Bharat Biotech, and Sinoppharm, and Gamaleya Research Institute of Epidemiology and Microbiology have come up with different vaccines, their efficacies on the mutant strains of the virus are still being documented and researched. This article deals with the current scenario, the nature of the virus, and the treatment against the viruses.
