Causes of COVID-19
COVID-19 is caused by the SARS-CoV-2 virus, which is part of the coronavirus family. Coronaviruses are known to cause illnesses ranging from the common cold to severe respiratory infections like SARS (Severe Acute Respiratory Syndrome) and MERS (Middle East Respiratory Syndrome).
Respiratory Droplets
- Released when an infected person coughs, sneezes, or talks.
Airborne Transmission
- Small virus-containing particles can linger in the air.
Contaminated Surfacesto Endemic Regions
- Touching surfaces with the virus and then touching the face.
Close Contact with Infected Individuals
- Household members and caregivers are at high risk.
Prevention of COVID-19
- Vaccination – Strongest protection against severe illness
- Mask-wearing – Reduces airborne transmission
- Hand hygiene – Frequent handwashing with soap
- Social distancing – Avoid crowded places
- Ventilation – Improves indoor air circulation
Combining these measures effectively reduces infection risk.

COVID-19 has now transitioned from a pandemic to an endemic virus in many countries, meaning it will continue circulating but at manageable levels.
Regions with Higher COVID-19 Cases:
- North & South America (USA, Brazil, Mexico)
- Europe (UK, France, Germany, Italy)
- Asia (India, China, Indonesia)
- Africa (South Africa, Nigeria)
Global vaccination efforts aim to control outbreaks.
