YWN has just recieved an alert from the DOHMH Alert concerning the outbreak of mumps in Brooklyn:
Since August 21, 2009, the New York City Department of Health and Mental Hygiene (NYC DOHMH) has been investigating an outbreak of mumps that began among children from Borough Park who attended summer camp in Upstate New York. Cases of mumps have continued to occur in Borough Park since the onset of the school year. At this time, there are 57 confirmed or probable cases and additional suspect cases are under investigation. Cases have ranged in age from 1 to 42 years, with the majority occurring among children age 10-15 years. Twenty-five per cent of cases either did not have two doses of mumps containing vaccine or had unknown vaccination status, while the remaining 75% had two documented doses of mumps containing vaccine.
Mumps is an illness characterized by acute onset of unilateral or bilateral tender, self-limited swelling of the parotid or other salivary gland, lasting 2 or more days, and without other apparent cause. Rare complications of mumps include orchitis, mastitis, oophoritis, deafness, and encephalitis. The infectious period for mumps is from 2 days before onset of symptoms to 5 days after symptoms appear. The incubation period for mumps from exposure to onset of illnes s ranges from12-25 days.
Children who are not fully vaccinated against mumps are at the highest risk of infection. Individuals who have received two doses of mumps vaccine (preferably as MMR) are at significantly lower risk of developing mumps but outbreaks have been seen among fully vaccinated individuals.
Mumps is spread via large respiratory droplets. A contact is an individual who had face-to-face contact, within three feet of a presumed mumps case, or an individual who had direct contact with the case’s respiratory secretions. A list of potential contacts should be obtained and their immunity to mumps should be determined. Non-immune contacts are at risk for developing mumps and should be isolated at home from day 12 through day 25 after exposure. Vaccination is NOT considered effective post-ex posure prophylaxis against mumps, but MMR vaccination should be offered to non-immune contacts that do not have a contraindication to MMR vaccination to protect against subsequent exposures.
In the healthcare settings, suspect mumps cases should be given a mask to wear; healthcare providers should institute standard and droplet precautions. Exposed healthcare workers who do not have evidence of immunity at the time of exposure should stay home for the incubation period of 12 days through day 25 after exposure.
All suspected of cases of mumps should be reported to the Bureau of Immunization at 212-676-2288.
