3. Note when treating dengue fever
For mild dengue fever, the patient can be treated at home as prescribed by the doctor.

Dengue is transmitted by the mosquito Aedes aegypti, so mothers with dengue fever can still breastfeed normally.If you have a high fever, only reduce fever with a single Paracetamon drug, use 10-15mg/kg/time for 4-6 hours. It is not recommended to use aspirin, ibuprofen because it can cause heavier bleeding.
Dengue fever in children is often more severe than in adults. Children with dengue fever are more susceptible to shock and re-shock than adults.
For children, by day 4, the fever has started to disappear and there are no other symptoms, meaning the disease is in remission but still need to continue to be monitored. If the baby shows warning signs such as lethargy or lethargy, liver pain, vomiting a lot, urinating less, mucosal bleeding... it must be taken to the hospital for re-examination.
