Covid-19

Emerging in late 2019, the new coronavirus SARS-CoV-2 quickly spread worldwide, becoming a pandemic. When an infected individual talks, coughs, or sneezes, it mostly spreads by respiratory droplets. Particularly among the elderly and those with existing medical problems, the virus affects individuals differently—from mild flu-like symptoms to severe pneumonia, respiratory failure, and death. 
Though some people may stay asymptomatic, common symptoms include fever, coughing, tiredness, and loss of taste or smell. Controlling the spread has mostly depended on preventive actions, including hand hygiene, mask-wearing, social separation, and immunisation.
Many successful vaccines that greatly lessen the risk of severe disease and hospitalisation have come as a result of worldwide efforts. New varieties have surfaced in spite of general vaccination, which underscores the importance of constant surveillance and flexibility in public health policies.
Not only on healthcare systems but also on mental health, education, tourism, and the world economy has the epidemic had broad effects on. It underlined the need for readiness, cooperative science, and a strong healthcare system. Constant awareness and ethical behaviour are still very vital as the globe develops in order to stop the next pandemics and protect societies.
