In most instances, fifth disease is a relatively mild, self-limited rash illness of childhood; recent studies indicate, however, that infection with parvovirus B19 in rare instances can lead to serious complications in people who are immunosuppressed.
When to keep your child home: By the time the rash appears, children are no longer contagious and do not need to stay home.

Hand, Foot & Mouth Disease
Hand, foot, and mouth disease is a mild viral illness that can occur at any age, occurring most often in children under age 10. The disease is characterized by vesicles (small blisters which contain clear fluid) that occur inside the mouth, on the gums and on the side of the tongue. On rare occasions, person’s with the virus that causes hand, foot, and mouth disease may develop viral meningitis. Infants who develop oral vesicles may stop nursing and become dehydrated. Most cases of hand, foot, and mouth disease occur in summer and fall.
When to keep your child home: Students can come to school unless fever is present or child cannot maintain hygiene or avoid close contact with others.

Pediculosis (Head Lice)
Pediculosis is an infestation of head lice, which infect the head and neck and attach their eggs to the base of the hair shaft. Lice move by crawling and cannot hop or fly. The lice feed on human blood, which can cause severe local itching. Head lice infestation is spread most commonly by close person-to-person contact. Dogs, cats, and other pets do not play a role in the transmission of human lice.
Each school year the issue of head lice becomes a concern for some families. The following evidenced based information is intended to increase head lice awareness so that parents can take steps at home to help prevent their children from acquiring head lice.
Parents should examine their child's head regularly, especially behind the ears and at the nape of the neck, for crawling lice and nits, if your child exhibits symptoms of a head lice infestation. If crawling lice or nits are found, all household members should be examined for crawling lice and nits every 2 to 3 days.
- Persons with live (crawling) lice or nits within 1/4 inch or less of the scalp should be treated. Do not treat any individual that does not have lice.
- Only 1 in 10 transmissions occur at school.
- The most common outbreaks are seen at the start of the school year, after winter break, spring break, all times when the students are out of school for extended periods.
- At the time live lice are found, the student has probably had the infestation for a while.
- Transmission occurs most often during playdates and sleepovers.
- Transmission can occur from shared hair care items, hats, etc. but is less likely.
- Lice do not jump and do not have wings so they cannot fly. They crawl.
- Children diagnosed with live head lice do not need to be sent home early from school; they can go home at the end of the day, be treated, and return to class after appropriate treatment has begun. Nits may persist after treatment, but successful treatment should kill crawling lice.
- Head lice can be a nuisance but they have not been shown to spread disease. Personal hygiene or cleanliness in the home or school has nothing to do with getting head lice.
- If you find head lice on your child, please notify the school and properly treat him/her at home. Continue to examine all family members for 2 weeks.
When to keep your child home: Child may return after their hair has been treated, clothes changed and there are no live lice present.

The National Association of School Nurses, American Academy of Pediatrics and the Center for Disease Control (CDC) all agree that classroom and/or school wide head lice screening programs have not had a significant effect on the incidence of head lice in the school setting over time and have not proven to be cost effective and therefore no longer recommend this practice. Doing these screenings also makes it impossible to protect the privacy and confidentiality of the students.
