Differentiating COVID-19 and Influenza co-infection from other Diseases
- Influenza and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. Influenza is caused by infection with influenza viruses and COVID-19 is caused by infection with the coronavirus (SARS-CoV-2). Testing may be needed to help confirm a diagnosis because some of the symptoms of flu and COVID-19 are similar. Influenza and COVID-19 share many characteristics, but there are some key differences between the two.
- This table compares the Influenza and COVID-19:
| Similarities | Differences | |
|---|---|---|
| Signs and symptoms | - It can be vary from no symptoms to sever symptoms.
- Common symptoms include: Fever/chills, cough, shortness of breath, fatigue, sore throat, runny nose, muscle aches, headache, and gastrointestinal symptoms (vomiting and diarrhea). |
- Change in or loss of taste or smell can be a sign of COVID-19. |
| Incubation period | - It takes one or more days for a person to get infected and develop symptoms after the exposure. | - It takes longer to develop symptoms in COVID-19 than Influenza.
- The time range can be vary in COVID-19, symptoms can appear early in 2 days or late in 14 days. - In Influenza, symptoms may develop 2 to 4 days after infection. |
| Period of Contagiousness | - A person can spread the virus for 1 day before the appearance of any symptoms. | - The period of contagiousness is longer in COVID-19, a person can spread the virus for about 2 days before having any symptoms and remain contagious for at least 10 days after experience any signs or symptoms. Asymptotic or after the symptoms disappeared, It can be contagious for 10 days after testing positive for COVID-19.
