📖 Content of Health Talk

1. Introduction

Greeting: "Good morning respected madam/sir and dear community members. My name is [Your Name], and I am a nursing student from [College Name]. Today I am going to give a health talk on prevention of dengue fever."

Ice-Breaking: "Many people think mosquitoes breed only in dirty drains, but dengue mosquitoes commonly breed in clean stagnant water around our homes such as coolers, flower pots, tyres, buckets, and water tanks. Today we will learn how to prevent dengue by stopping mosquito breeding."

Key Message: "No stagnant water, no mosquito breeding, no dengue."

2. Definition of Dengue Fever

Dengue fever is an acute viral infection caused by dengue virus and transmitted to humans through the bite of infected female Aedes mosquitoes, mainly Aedes aegypti. It may cause high fever, severe body pain, headache, rash, vomiting, bleeding tendency, and in severe cases shock or death if not treated early.

3. Causative Agent and Mode of Transmission

4. Important Facts About Aedes Mosquito

• Aedes mosquito is black with white stripes on body and legs.
• It commonly bites during daytime.
• It breeds in clean stagnant water, not only dirty water.
• Eggs can survive in dry containers for many months.
• It usually flies for a short distance, so breeding places are often near homes.
• Removing stagnant water every week is the most important prevention method.

5. Common Breeding Places of Dengue Mosquito

6. Signs and Symptoms of Dengue Fever

• Sudden high fever.
• Severe headache.
• Pain behind the eyes.
• Severe muscle and joint pain, also called break-bone fever.
• Nausea and vomiting.
• Skin rash.
• Weakness and tiredness.
• Mild bleeding from nose or gums in some cases.

7. Warning Signs of Severe Dengue

Warning signs usually appear when fever starts decreasing. These signs should never be ignored.

8. Diagnosis of Dengue Fever

• Diagnosis is done by clinical assessment and laboratory tests.
• Blood tests may include NS1 antigen, IgM/IgG antibody test, platelet count, hematocrit, and complete blood count.
• Self-diagnosis should be avoided.
• Fever with warning signs should be checked immediately at a health facility.

9. Treatment and Home Care

There is no specific antiviral medicine for dengue. Treatment is mainly supportive and should be done according to medical advice.

• Take adequate rest.
• Drink plenty of fluids such as water, ORS, coconut water, soup, and fresh fluids.
• Take paracetamol only for fever as advised by doctor.
• Avoid aspirin, ibuprofen, diclofenac, and other painkillers unless prescribed, because they may increase bleeding risk.
• Do not take antibiotics or injections unnecessarily.
• Monitor fever, urine output, bleeding, and weakness.
• Visit health facility immediately if warning signs appear.

10. Prevention of Dengue Fever

Dengue prevention mainly depends on controlling mosquitoes and preventing mosquito bites.

A. Source Reduction — Stop Mosquito Breeding

• Empty and scrub coolers, buckets, drums, and containers every week.
• Cover water tanks and stored water containers tightly.
• Remove water from flower pot plates, tyres, broken bottles, coconut shells, and discarded items.
• Clean roof gutters and drainage areas.
• Fill pits and low areas where water collects.
• Keep surroundings clean and dry.
• Observe one fixed day every week as Dry Day to check and remove stagnant water.

B. Personal Protection from Mosquito Bites

• Wear full-sleeved clothes and long pants.
• Use mosquito nets, especially for children, elderly people, and sick persons.
• Use mosquito repellents as advised and avoid contact with eyes/mouth.
• Use window and door screens.
• Keep doors and windows closed during peak mosquito biting time.
• Use mosquito coils/vaporizers safely and away from children.

C. Community Measures

• Participate in community cleanliness drives.
• Inform health workers about fever clusters in the community.
• Cooperate with fogging and larval control activities.
• Do not throw waste materials where water can collect.
• Educate neighbors and family members about dengue prevention.

11. Do’s and Don’ts in Dengue
