For delays of more than 24-48 hours (e.g., when shipping specimens from an outside facility), specimens should be processed as needed and rapidly frozen to -70C and then transported to the laboratory on dry ice.
Specimens for molecular testing should not be stored at room temperature or frozen at -20C.
Specimens should be transported to the laboratory as quickly as possible after collection. When imme
Amplification and detection of mumps virus RNA using real-time TaqMan PCR and nucleic acid primer/probe pairs specific for conserved regions of the mumps virus genome. This test is performed pursuant to an agreement with Roche Molecular Systems, Inc.
Following an incubation period of 14-18 days, mumps begins with a nonspecific prodrome of low-grade fever, headache, respiratory symptoms, malaise, and myalgia. Most common feature is swelling of salivary glands in 30-40%, particularly the parotid glands. Swelling is usually bilateral; unilateral in 25% of cases. Severe illness with complications more likely in adults. The virus is transmitted from person to person through respiratory secretions and is quite contagious. Greatest communicability is 1-2 days before to 5 days after onset of parotid gland swelling. Illness lasts a week to 10 days. Complications include orchitis in 20-30% of infected postpubescent males, oophoritis and mastitis in 5% of postpubertal females; sterility and impaired fertility are uncommon. Mumps can also be complicated by meningitis and encephalitis.
Clinical diagnosis of mumps is unreliable; requires laboratory confirmation. Although once a common disease in children, fewer physicians now recognize the clinical features of mumps. Also, many viruses, including parainfluenza virus, enteroviruses, EBV, CMV, HIV, and influenza virus, can cause acute parotitis. Mumps virus PCR is most useful in detecting mumps virus RNA from buccal/throat swabs, urine, blood, and CSF (for meningitis/encephalitis) specimens to diagnose acute disease in unvaccinated or previously vaccinated individuals. Outbreaks of mumps still occur in the United States despite high coverage rates with vaccine. The disease is normally imported from abroad or associated with importation from other countries and outbreaks arise in people who have not been immunized and as a result of two-dose vaccine failure. Therefore, both unvaccinated and vaccinated persons are at risk for acquiring mumps themselves and transmitting the virus to others. Living in closed communities in crowded conditions is a contributing factor in the spread of the virus.
