Dengue fever IgG positive and IGM positive

Dengue Fever: IgG Positive and IgM Positive

Dengue fever is a mosquito-borne viral infection that can cause 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 fever is a major public health problem in many tropical and subtropical regions of the world. According to the World Health Organization (WHO), an estimated 390 million dengue infections occur each year, resulting in approximately 20,000 deaths.

The diagnosis of dengue fever is based on clinical symptoms and laboratory tests. The most common symptoms of dengue fever include:

Fever

Headache

Muscle and joint pain

Nausea and vomiting

Rash

Bleeding

Laboratory tests can be used to confirm the diagnosis of dengue fever. These tests include:

Dengue virus IgM antibody test: This test detects IgM antibodies, which are produced by the body in response to a recent infection. A positive IgM antibody test indicates that the person has a current or recent dengue infection.

Dengue virus IgG antibody test: This test detects IgG antibodies, which are produced by the body in response to a past infection. A positive IgG antibody test indicates that the person has had a past dengue infection.

The interpretation of dengue virus antibody test results can be complex. The following table provides a general overview of the interpretation of dengue virus antibody test results:

| IgM antibody test | IgG antibody test | Interpretation |

|---|---|---|

| Positive | Negative | Acute dengue infection |

| Positive | Positive | Recent dengue infection or past dengue infection with reinfection |

| Negative | Positive | Past dengue infection |

| Negative | Negative | No recent or past dengue infection |

Dengue fever is a treatable disease. There is no specific antiviral treatment for dengue fever, but supportive care can help to relieve symptoms and prevent complications. Treatment may include:

Rest

Fluids

Pain relievers

Anti-nausea medication

In severe cases, dengue fever can lead to complications such as:

Dengue hemorrhagic fever (DHF): This is a severe form of dengue fever that can cause bleeding, shock, and organ failure.

Dengue shock syndrome (DSS): This is a life-threatening complication of DHF that can lead to death.

There is a vaccine available to prevent dengue fever. The vaccine is safe and effective, and it is recommended for people who live in areas where dengue fever is common.

Dengue fever is a serious disease, but it can be prevented and treated. If you are traveling to an area where dengue fever is common, take steps to protect yourself from mosquito bites. If you develop symptoms of dengue fever, see your doctor immediately.
