SARS-CoV-2 (COVID-19)

The SARS-CoV-2, the virus responsible for COVID-19, is a coronavirus that has made recent history due to its ability to spread rapidly worldwide. It primarily infects the respiratory tract by attaching to cells through its famous "spike" protein, allowing it to enter and multiply. Symptoms vary greatly from person to person: some show no signs, while others experience fever, cough, fatigue, loss of taste or smell, muscle pain, or difficulty breathing. In more severe cases, especially among the elderly or vulnerable, the infection can progress to significant lung damage.

The virus is mainly transmitted through respiratory droplets and aerosols emitted when a person speaks, coughs, or sneezes, as well as by contact with contaminated surfaces, although this mode is less common. Once in the body, it triggers an immune response responsible for most symptoms. There is no "instant cure," but the vast majority of people recover naturally with rest, hydration, and supportive care. Antiviral and medical treatments are available for at-risk individuals or those with more severe forms, and have significantly improved management.

Prevention relies on now well-known measures: vaccination, handwashing, ventilation of spaces, mask-wearing in certain situations, and isolation if symptoms appear. Vaccination plays a key role in reducing severe forms and complications, making SARS-CoV-2 a striking example of rapid advances in science and public health.
