What are signs and warning indicators of dengue illness?

Question

Hi doctor,

I recently heard about the outbreak of dengue fever, and I am concerned about the risk of contracting the disease. Could you provide me with detailed information on the current situation of dengue fever, particularly in my region? I am interested in learning about the preventive measures the Pan American Health Organization recommended to avoid mosquito bites and reduce the risk of dengue fever transmission.

Additionally, I would like to know the common symptoms of dengue fever, and when to seek medical attention if I suspect, I have been infected. Your guidance on how to stay safe during this outbreak would be greatly appreciated.

Thanks.

Hi,

Welcome to icliniq.com.

I understand your concern.

Dengue is common. Most dengue cases reported in the 49 continental U.S. states occur in travelers infected elsewhere.

Preventive measures:

1. Eliminate or reduce mosquito breeding sites around your home by removing standing water from containers such as flowerpots, buckets, and discarded tires.

2. Apply insect repellent containing picaridin, oil of lemon eucalyptus, or IR3535 on exposed skin and clothing. Follow the product instructions carefully, especially when applying to children.

3. Wear protective clothing, long-sleeved shirts, long pants, socks, and shoes to minimize exposed skin outdoors, especially during peak mosquito activity times such as dawn and dusk.

4. Sleep under mosquito nets, especially if you live in or travel to areas with high dengue transmission.

5. Keep windows and doors closed or screened to prevent mosquitoes from entering your home.

6. Stay in accommodations with air conditioning or screens on windows and doors to keep mosquitoes out.

7. Support community-based mosquito control efforts, such as eliminating standing water in public spaces and implementing insecticide spraying programs.

Dengue fever symptoms typically include:

High fever.
Severe headache.
Pain behind the eyes.
Joint and muscle pain.
Nausea and vomiting.
Rash.

In severe cases, dengue fever can progress to dengue hemorrhagic fever or dengue shock syndrome, which are life-threatening conditions characterized by severe bleeding, organ impairment, and shock.

I suggest you seek medical help if:

You develop symptoms of dengue fever, especially if you live in or have recently traveled to an area with known dengue transmission.
Your symptoms worsen, or you experience severe abdominal pain, persistent vomiting, bleeding from the nose or gums, difficulty breathing, or signs of shock (such as cold or clammy skin, rapid pulse, and confusion).

I hope this information will help you.

Thanks.
