2 to 3 weeks
|
1. Exclude from school until vesicles are dry and crusted.

than six days after last crop of vesicles
|
Virus spread directly from person through discharge from
the nose and mouth, also by discharge from the skin and mucous membranes
of infected persons. Readily communicable. One attack usually confers immunity.
Children on immunosuppressive drugs at high risk. |

|
|
Cold Sores

Vesicles usually on lips but may occur anywhere on skin
or in mucous membranes. May be confused with Impetigo. |
2 to 12 days
|
1. No restriction.
2. May be communicable as long as seven weeks after lesion
appears. |
Virus is transmitted by direct contact with infected
persons, a majority of whom have no apparent infection. |
|
|
|
|
|
| Common Cold |
Acute upper respiratory signs, including watery eyes,
sneezing, running nose, general feeling of illness. |
12 hours to 3 days
|
1. No restrictions unless ill.
