Taking medicine to treat dengue fever does not go away, what should I do?

Question:
Hello doctor! My wife was diagnosed with mild dengue fever, the test report was negative for Dengue, but after taking the medicine for 3 days, the fever still didn't go away, then had to go to another doctor because the hospital was closed on Saturday. , here the doctor again diagnosed my wife with viral fever, high liver enzymes and negative Dengue test results. My wife was prescribed drugs to lower liver enzymes and vitamin C but now the fever has not gone away, the time has lasted until the 7th day. So the doctor asked me if my wife's condition is so dangerous? Thanks for the advice doctor!

Hello! Dengue fever is a contagious viral disease transmitted by two species of mosquitoes, the midges (Aedes aegypti) and the Asian tiger mosquito (Aedes albopictus). After being bitten by a mosquito, an infected person can incubate for 4-7 days.
After that, a high fever of 39-40 degrees Celsius begins. High fever lasts for 2 to 7 days, then returns to normal or even slightly lower than normal, but the fever can return. The fever can come back and last for days. Common symptoms following a fever include severe headache in the frontal area, pain behind the eyes, severe muscle and joint pain, nausea and vomiting, fatigue, and rash. Although there is no cure for dengue, medical attention is essential due to the risk of developing bleeding problems from the disease. Most patients will feel better in about 2 weeks with overall care. In case your wife has a high fever that does not go away, you should take her to a hospital of Vinmec Health System to be examined by a specialist doctor and given an appropriate treatment plan.
Thank you for submitting your question to Vinmec. Wish your family a lot of health. Best regards!
