Coronavirus (COVID-19)

The Novel Coronavirus disease is an infectious disease caused by a newly discovered coronavirus (COVID-19). In humans, coronaviruses cause respiratory tract infections that can range from mild (common cold) to lethal (SARS, MERS, and COVID-19) and recover without requiring special treatment and in birds and mammals also cause various diseases. People with medical problems like diabetes, chronic respiratory disease, cardiovascular disease, and cancer and also in elder are more likely to develop serious illness. At present, no specific treatment is there for disease caused by a novel coronavirus.However, the virus continues to evolve, leading to the emergence of new variants, such as the Delta and Omicron strains, which have raised concerns about transmissibility and vaccine efficacy. Research into COVID-19 has advanced rapidly, leading to a greater understanding of the virus’s structure, replication, and impact on human health. Scientists have focused on antiviral treatments and monoclonal antibody therapies to treat infected individuals, in addition to the ongoing efforts to vaccinate populations globally. Despite significant progress, challenges remain in managing the spread of the virus, especially in regions with limited access to healthcare or vaccines. Continued vigilance, scientific innovation, and global cooperation are essential to controlling the pandemic and mitigating its long-term effects on public health.
