Dengue virus IgM positive meaning
Dengue fever is a mosquito-borne viral infection that causes a wide range of symptoms, from mild fever to severe, life-threatening illness. The virus is transmitted to humans through the bite of an infected Aedes mosquito.
Dengue IgM positive means that a person has been recently infected with the dengue virus. IgM is a type of antibody that is produced by the body in response to infection. IgM antibodies are usually detectable in the blood within a few days of infection and can remain detectable for several weeks.
A positive IgM test result indicates that a person is currently infected with the dengue virus or has been recently infected. The test can be used to diagnose dengue fever in people who have symptoms of the disease. It can also be used to screen people for dengue virus infection in areas where the virus is known to be circulating.
