A Review on Viral Outbreak in India with Special Reference to COVID-19

Abstract

COVID-19, Middle East respiratory syndrome (MERS), and SARS are three severe pandemics linked to novel coronaviruses that have so far impacted people in the twenty first century. These acute respiratory tract infections (ARTIs) are brought on by viruses that are all exceedingly contagious and/or have caused large mortality. On January 7, 2020, a patient in Wuhan, China, with pneumonia-like symptoms had a novel coronavirus found in lung fluid. In 1980, the smallpox disease was formally deemed extinct worldwide. The cause of smallpox is unknown. The discovery of smallpox-like lesions on Egyptian mummies indicates that the illness has existed for at least 3000 years. The Ebola virus, a member of the filovirus family that affects both humans and other primates, causes the severe illness known as Ebola virus disease (EVD). The idea that swine influenza was a sickness related to human flu was originally put forth when pigs were ill during the 1918 flu pandemic at the same time as humans. Because viruses vary in their structural, anatomical, and molecular makeup, distinct viral diseases can be detected or tested using different methodologies, procedures, or diagnostic tools. Viral vaccines come in a wide variety of varieties in the pharmaceutical industry. From a medical perspective, several treatments are used for various viral illnesses.
