General Description
Parotitis (Mumps) as well as Measles, Parainfluenza and RS-viruses belong to the family of paramyxoviridae. Parotitis viruses are globally spread; humans are the only natural host. The virus is spread by droplet infection and enters the body through the upper respiratory tract. Parotitis Viruses are less contagious (40 %) than Measles and Varicella-Zoster Viruses. The highest number of incidents is observed in industrial countries among children at the age of 5-9.
The clinical picture of parotitis (parotitis epidemica, mumps) was first described by Hippocrates. Symptoms are one-sided or bilateral parotitis. Parotitis infections are relatively mild during childhood but can lead to complications in adults. Single as well as combination vaccines, like measles-parotitis or measles-parotitis-rubella, are available. Live vaccines (attenuated virus strains) provide long-lasting immunity.
Besides clinical diagnosis of Parotitis Virus infection with significant swellings, diagnosis is also performed with serological methods especially when main symptoms are missing.
Since introduction of protective vaccination, interest in laboratory diagnostics has grown.
Detection of antibodies in serum is possible with ELISAs, CFT and HHT. Immunoglobulin specific ELISAs are adapted for routine diagnostics. Direct detection of Parotitis Viruses e.g. by PCR is a complementary method.
