On average, a person with COVID-19 is contagious for eight days. However, this is an average, and the contagious period can vary. Several factors influence the duration of contagiousness, including the severity of illness and underlying health conditions.
Factors Affecting Contagious Period
- Severity of Illness: Individuals with milder symptoms may be contagious for a shorter period than those with severe illness.
- Underlying Health Conditions: Pre-existing health issues can impact the duration of contagiousness.
Contagious Period Timeline
While the average is eight days, some studies suggest the contagious period can range from:
- One to two days before symptom onset: You can spread the virus even before you realize you're sick.
- Up to eight to ten days after symptom onset: This is the maximum duration reported in many studies.
It's crucial to remember that these are estimates, and individual experiences can differ.
