Here it says:
The time from exposure to symptom onset (known as the incubation period) is thought to be two to 14 days, though symptoms typically appear within four or five days after exposure.
We know that a person with COVID-19 may be contagious 48 hours before starting to experience symptoms. People may actually be most likely to spread the virus to others during the 48 hours before they start to experience symptoms.
if symptoms started 2 days after exposure based on above (incubation period), and people are contagious 48 hours before starting to experience symptoms also as stated above, does it mean after exposure to covid person is immediately able to infect others?
After how many days after exposure is someone contagious?
