how long is pink eye contagious viral
For example, bacterial and viral causes of pinkeye are almost always contagious and are spread from person to person. However, pinkeye caused by allergens and chemical irritants is not contagious by person-to-person contact. Pinkeye that is contagious has an incubation period as long as 14 days. However, most doctors do not think that pinkeye becomes contagious to other people until symptoms start to develop.
