Symptoms
Symptoms appear within a week after a mosquito bite. The acute phase lasts 3 to 4 days. Then symptoms go away. At the end of the acute phase, some people move to the toxic phase.
Some may not have symptoms. Those who do may have:
Acute phase:
- Fever and chills
- Headache
- Muscle pain
- Loss of appetite
- Nausea or vomiting
Toxic phase:
- High fever
- Belly pain
- Bleeding from the gums, nose, eyes, or stomach
- Vomit that appears black—caused by bleeding
- Yellowing of the skin—jaundice
- Confusion, seizure, or coma
Treatments
Treatment
The goal of treatment is to ease symptoms. It may include:
- Fluids by mouth or IV to prevent dehydration
- Medicines to lower fever and pain
- Dialysis (toxic phase) to help kidneys filter waste
- Transfusion (toxic phase) to replace blood lost through bleeding
