Dengue Fever IgM and Egg Types
Dengue fever is a mosquito-borne viral infection that can cause a wide range of symptoms, from mild fever to severe illness. The virus is transmitted through the bite of an infected Aedes mosquito.
IgG and IgM Antibodies
When someone is infected with dengue virus, their body produces antibodies to fight the infection. These antibodies are called immunoglobulins (Igs). There are different types of Igs, including IgG and IgM.
IgG antibodies are produced later in the infection and can provide long-term immunity to the virus.
IgM antibodies are produced early in the infection and can be used to diagnose an acute dengue infection.
Egg Types
Type 1
Virions are large (100-120 nm)
Surface glycoproteins: E, C, M
Antigens: NS1, NS2A, NS2B, NS3, NS4A, NS4B, NS5
Type 2
Virions are small (80-100 nm)
Surface glycoproteins: E, C, M
Antigens: NS1, NS2A, NS2B, NS3, NS4A, NS4B, NS5
Type 3
Virions are medium (90-110 nm)
Surface glycoproteins: E, C, M
Antigens: NS1, NS2A, NS2B, NS3, NS4A, NS4B, NS5
Type 4
Virions are large (100-120 nm)
Surface glycoproteins: E, C, M
Antigens: NS1, NS2A, NS2B, NS3, NS4A, NS4B, NS5
Dengue Diagnosis
IgM Antibody Test
The IgM antibody test is a blood test used to diagnose an acute dengue infection. The test looks for IgM antibodies to the dengue virus in the blood. A positive IgM antibody test indicates that the person has a current dengue infection.
IgG Antibody Test
The IgG antibody test is a blood test used to determine if someone has been previously infected with dengue virus. The test looks for IgG antibodies to the dengue virus in the blood. A positive IgG antibody test indicates that the person has been previously infected with dengue virus and has developed immunity to the virus.
Treatment for Dengue Fever
There is no specific treatment for dengue fever. Treatment is supportive and focuses on relieving symptoms and preventing complications. Treatment may include:
Rest
Fluids
Pain relievers
Antipyretics
Hospitalization for severe cases
Prevention of Dengue Fever
There is no vaccine to prevent dengue fever. However, there are a number of things that can be done to prevent infection, including:
Using mosquito repellent
Wearing long sleeves and pants
Staying in air-conditioned areas
Using mosquito nets
Eliminating mosquito breeding grounds
Complications of Dengue Fever
Dengue fever can lead to a number of complications, including:
Dengue hemorrhagic fever (DHF)
Dengue shock syndrome (DSS)
Encephalitis
Meningitis
Myocarditis
Liver failure
Kidney failure
Death
Dengue Fever and Pregnancy
Dengue fever can be more severe in pregnant women. Pregnant women who are infected with dengue virus are at increased risk for developing DHF, DSS, and other complications. Dengue fever can also cause miscarriage, stillbirth, and birth defects.
Dengue Fever in Children
Dengue fever is a common childhood illness in areas where the virus is endemic. Children who are infected with dengue virus are at increased risk for developing DHF, DSS, and other complications. Dengue fever can also cause death in children.
