COVID-19

COVID-19 is a respiratory illness caused by the SARS-CoV-2 virus, which emerged in late 2019 and rapidly spread to become a global pandemic. The disease primarily affects the respiratory system but can also impact multiple other organs, and severity ranges from asymptomatic or mild infection to severe pneumonia and respiratory failure. Transmission occurs mainly through respiratory droplets and airborne particles, particularly in enclosed, poorly ventilated spaces. Widespread vaccination and prior infection have substantially reduced the severity of illness in most populations, though the virus continues to circulate with new variants.

The most common symptoms include: Fever or chills; dry cough; shortness of breath; fatigue. Early recognition is key to prompt diagnosis and effective treatment.

Yes, COVID-19 is contagious. It can spread from person to person. Practice good hygiene, avoid close contact with infected individuals, and follow isolation guidelines if advised by a doctor.

Treatment options include: Most cases are managed with supportive care including rest; hydration; and fever-reducing medications. Treatment should always be guided by a qualified Infectious Diseases specialist. Do not self-medicate.

While COVID-19 cannot always be fully prevented, several measures can reduce risk: Vaccination and staying up to date with booster doses; wearing masks in crowded or high-risk settings; good hand hygiene.

Consult a Infectious Diseases specialist if symptoms persist for more than a few days, worsen despite home care, or significantly affect your daily activities. Early diagnosis leads to better outcomes.
