Corona virus (COVID 19)

COVID-19: "Coronavirus Disease 2019," is an infectious disease caused by the novel coronavirus SARS-CoV-2. It was first identified in December 2019 in Wuhan, Hubei province, China, and quickly spread globally, leading to a pandemic declared by the World Health Organization (WHO) in March 2020.COVID-19 primarily spreads through respiratory droplets when an infected person coughs, sneezes, or talks, and it can also spread by touching surfaces contaminated with the virus and then touching the face, especially the mouth, nose, or eyes. The symptoms of COVID-19 can range from mild to severe and may include fever, cough, shortness of breath, fatigue, muscle or body aches, headache, loss of taste or smell, sore throat, congestion, nausea or vomiting, and diarrhea. Severe cases can lead to pneumonia, acute respiratory distress syndrome (ARDS), organ failure, and death, particularly in older adults and those with underlying health conditions.

To control the spread of COVID-19, public health measures such as wearing masks, practicing physical distancing, frequent handwashing, and avoiding large gatherings have been recommended by health authorities worldwide. Vaccination campaigns have also been launched globally to provide immunity against the virus, with multiple COVID-19 vaccines authorized for emergency use.The COVID-19 pandemic has had profound social, economic, and public health impacts, disrupting daily life, straining healthcare systems, and causing significant loss of life worldwide. Efforts to control the spread of the virus and mitigate its effects continue through vaccination campaigns, public health interventions, and ongoing research into treatments and prevention strategies.
