The incubation period ranges from 2-7 days. Up to 80% of all dengue infections are asymptomatic and only about 20% will show signs and symptoms and some may go into severe forms like Dengue Haemorrhagic fever and Dengue Shock Syndromes causing bleeding and drop in blood pressure.
Common symptoms

• Severe joint and muscle pains.
• Severe headache.
• Retro-orbital pain.
• Skin rash.
• Swollen lymph glands.
Symptoms of severe dengue
• Abdomen pain and tenderness.
• Vomiting blood or blood in stool.
• Mild bleeding from nose and gums.
• Fatigue, restlessness or irritability.
Prevention
• No vaccination can prevent all 4 serological types of dengue.
• Dengue can only be avoided by preventing mosquito bites. Protect yourself to avoid infecting others. Use mosquito repellent, wear long-sleeved clothing, and use mosquito nets while sleeping.
• Eliminate all mosquito breeding sites: All water storage containers should be covered. Remove/ destroy all disposable, unused materials lying in and around the house, like old tyres, broken pots, crockery etc.

10. Fogging: Don't rely solely on fogging, as it has side effects and doesn't eliminate mosquito eggs and larvae.
11. Dengue RDT: Be cautious with Dengue Rapid Diagnostic Tests (RDT); they can produce false positives. Confirm positive cases in sentinel site hospitals (Naga Hospital Kohima and Dimapur District Hospital). GOI and ICMR do not recommend the use of RDT for Dengue diagnosis.
