What is COVID-19?

COVID-19 is a viral respiratory illness caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Typical Symptoms of COVID-19

Diagnostic Questions for COVID-19

Your doctor may ask these questions to check for this disease:

  • Do you have joint pain in multiple joints throughout your body?
  • Do you have pain all over your body?
  • Do you have warm hands and feet?
  • Do you have a fever?
  • Do you have a headache?

Treatment of COVID-19

Early antiviral treatment can reduce the severity of symptoms and lower the risk of complications like hospitalization and death. It is especially recommended for people most at risk for severe disease like the very young, elderly or people with pre-existing conditions. Several antiviral medications can inhibit viral replication, especially when administered in the early stages of infection. This can help shorten the duration of symptoms and prevent progression to severe disease. In cases where COVID-19 leads to serious symptoms like difficulty breathing or respiratory failure, hospitalization may be required. Treatment may include oxygen therapy, antiviral medications, and supportive care. It's crucial to seek medical attention as early as possible to receive timely treatment and minimize risks.
