What is 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.
Moderate
Very common — global pandemic infection with the vast majority of the population having been infected or vaccinated
Yes
Causes of COVID-19
Caused by infection with the SARS-CoV-2 virus, spread primarily through respiratory droplets and aerosols released when an infected person coughs, sneezes, talks, or breathes. Close contact, indoor crowded settings, and poor ventilation increase transmission risk, while surfaces contaminated with the virus can occasionally serve as a secondary transmission route.
Symptoms of COVID-19
Fever or chills, dry cough, shortness of breath, fatigue, loss of taste or smell, sore throat, body aches, headache, congestion or runny nose, in severe cases difficulty breathing requiring hospitalization
Treatment & Types of COVID-19 in Maharashtra
Most cases are managed with supportive care including rest, hydration, and fever-reducing medications, while antiviral medications are used for eligible high-risk patients to reduce severity. Severe cases require hospitalization with oxygen support, corticosteroids to reduce inflammation, and in critical cases mechanical ventilation.
COVID-19 severity is classified as asymptomatic, mild (upper respiratory symptoms without breathlessness), moderate (pneumonia with normal oxygen levels), and severe or critical (pneumonia with low oxygen, respiratory failure, or multi-organ involvement). A subset of patients also develop long COVID, with symptoms such as fatigue or breathlessness persisting for weeks to months after the initial infection resolves.

Frequently Asked Questions
How long is someone with COVID-19 contagious?
Most people are most infectious in the first five days of symptoms, and isolation guidance typically recommends staying away from others until fever has resolved and symptoms are clearly improving.
Do vaccinated people still need to worry about COVID-19?
Vaccination greatly reduces the risk of severe illness and hospitalization even though breakthrough infections can still occur, so staying up to date with boosters remains worthwhile, particularly for older adults and those with chronic conditions.
What is long COVID?
It refers to symptoms such as fatigue, brain fog, or breathlessness that persist for weeks or months after the acute infection clears, and anyone with lingering symptoms beyond a few weeks should see a physician for evaluation and supportive management.
Who is most at risk of severe COVID-19?
Older adults and people with conditions such as diabetes, heart disease, obesity, or a weakened immune system face the highest risk of severe illness and should seek medical advice early if they test positive.
Is a COVID-19 test still necessary if symptoms are mild?
Testing helps confirm the diagnosis, guides isolation decisions, and identifies people who may benefit from antiviral treatment, so it is still worthwhile especially for high-risk individuals or before contact with vulnerable people.
