WHAT YOU NEED TO KNOW:
Dengue virus is carried by mosquitos. Dengue virus may cause a mild to severe viral infection. The virus is most commonly spread to a human through the bite of an infected mosquito. Dengue virus may be passed from a mother to her unborn baby. You may be at risk for dengue virus if you travel or live in an area with infected mosquitos. Mosquitoes are usually found near water. Examples include ponds, buckets of water, animal dishes, and flower pots. The number of infected mosquitos may increase during rainy or humid seasons.
Call 911 or have someone else call for any of the following:
- You have trouble breathing.
- You faint or lose consciousness.
Return to the emergency department if:
The following are warning signs that your infection is getting worse:
- Your heart is beating faster than usual.
- You urinate less than usual or not at all.
- You feel confused or anxious.
- Your skin is pale and feels cold or clammy.
- You have bruises or small red or purple dots on your skin.
- You feel weak, dizzy, or faint.
- You have severe abdominal pain.
- You cannot stop vomiting or you vomit blood.
- You have blood in your bowel movements or your bowel movements look like tar.
- You have irregular or heavy menstrual bleeding.
Contact your healthcare provider if:
- Your symptoms do not improve within 3 days.
- You are pregnant or think you are pregnant.
- You have questions or concerns about your condition or care.
- Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Read the labels of all other medicines you are using to see if they also contain acetaminophen, or ask your doctor or pharmacist. Acetaminophen can cause liver damage if not taken correctly. Do not use more than 4 grams (4,000 milligrams) total of acetaminophen in one day.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him of her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
Manage your symptoms:
- Do not take NSAIDs or aspirin. These medicines can increase your risk for bleeding.
- Drink plenty of fluids to prevent dehydration. You are at risk for dehydration if you have a fever, are vomiting, or have diarrhea. Ask how much liquid to drink each day and which liquids are best for you. You may need to drink an oral rehydration solution (ORS). This is a drink that contains the right amount of salt, sugar, and minerals in water. It is the best oral liquid for replacing your body fluids. Ask your healthcare provider where you can get an ORS. An ORS can be given in small amounts (about 1 teaspoon at a time) if you or your child is vomiting. If you or your child vomits, wait 30 minutes and try again. Ask healthcare providers how much ORS you or your child needs.
- Rest as directed. Ask your healthcare provider when you can return to your normal activities.
