Dengue has three stages
1. Stage 1 is when the patient has a fever between the first five days along with nausea, vomiting, and abdominal pain. If your baby looks weak and does not eat or drink sufficiently then you should seek medical help urgently.
2. Stage 2 is critical as the temperature drops down within 24 hours from 5-7 days. With the drop in temperature, the plasma leaks, and blood pressure levels will drop. The patient will feel weak, restless, catch cold, fast pulse, etc. Severe cases may even require critical care.
3. Stage 3 is a recovery stage when the patient takes a few more days to recover and get back to normal. The patient at this stage gains back his/her appetite, pulse rate slows down, and develops a convalescent rash on the legs and arms.
