Mumps is a contagious viral infection that can cause fever and swelling of the salivary glands. It is possible to get mumps more than once, although it is not common. In fact, while most people develop an immunity to the virus after they have recovered from their first infection, it is possible for a person to get mumps again.
Reinfection
Reinfection with mumps is rare and usually occurs when a person is exposed to the virus several months after their first infection. This is because the immunity that develops after the first infection typically lasts for many years. In some cases, however, the immunity may not be as strong as it was initially, and the person may be susceptible to reinfection.
Long-Term Complications
In rare cases, reinfection with mumps can lead to long-term complications. These may include deafness, meningitis, or encephalitis. It is important to note that reinfection with mumps is not the same as a relapse, which occurs when a person has an initial infection but fails to completely recover from it.
Preventing Reinfection
The best way to prevent reinfection with mumps is to get the MMR vaccine. This vaccine provides protection against mumps, measles, and rubella. It is recommended that all children receive two doses of the MMR vaccine, with the first dose given at 12 to 15 months of age and the second dose given at 4 to 6 years of age. Adults who have not received the MMR vaccine may also benefit from getting the vaccine.
