Let’s delve deeper into these elements to grasp how lengthy you may be contagious with COVID-19:
How Lengthy Contagious COVID
Understanding the period of contagiousness is essential for curbing the unfold of COVID-19. Listed below are 8 vital factors to know:
- Signs matter: Symptomatic people are usually extra contagious.
- Severity impacts: Extreme circumstances are likely to have longer contagious intervals.
- Immune response varies: Immunity impacts period of contagiousness.
- Viral load influences: Larger viral load means increased contagiousness.
- Variants differ: New variants could have totally different contagiousness patterns.
