Dengue recovery in adults
Informed by recognized medical guidance
Overview
Dengue is a viral illness spread by mosquitoes. It causes high fever, severe headache, and body aches. Most people recover within a few weeks, but rest and proper care are important for a full recovery.
Key facts
- Dengue is caused by a virus and spread through the bite of infected Aedes mosquitoes.
- Most people with dengue have mild symptoms and get better on their own.
- Severe dengue can be life-threatening, but it is rare and can be treated in a hospital.
Dengue is common in tropical and subtropical parts of the world, including Southeast Asia, the Pacific islands, the Caribbean, and Central and South America.
Anyone can get dengue, but adults who have had dengue before are at higher risk of developing severe dengue if they get infected again.
Symptoms
- Severe abdominal pain or tenderness
- Persistent vomiting (more than 3 times in a day)
- Bleeding from the nose or gums, or blood in vomit or stool
- Very fast or difficult breathing
- Cold, clammy skin or feeling faint
- Extreme fatigue or restlessness
- ⚠Fever that lasts more than 3 days without improvement
- ⚠Signs of dehydration (dry mouth, little or no urine, weakness)
- ⚠Severe headache or pain that does not go away with rest
Common symptoms
- High fever (sudden onset, often 39-40°C)
- Severe headache, especially behind the eyes
- Joint and muscle pain (often called 'breakbone fever')
- Nausea and vomiting
- Swollen glands
- A rash that may appear a few days after the fever
Symptoms in children
- In children, symptoms may be mild and can include fever, rash, and general discomfort. Sometimes children show no symptoms at all.
Symptoms in older adults
- Older adults may have more severe symptoms, such as higher fever, more intense pain, and a greater risk of dehydration and complications.
Causes
Main causes
- Dengue is caused by the dengue virus. It is spread when a mosquito bites an infected person and then bites a healthy person.
- The virus cannot spread directly from person to person.
Risk factors
- Living in or traveling to areas where dengue is common
- Previous infection with dengue (increases risk of severe dengue)
- Having a weakened immune system
When to see a doctor
See a doctor urgently if:
- If you or someone you care for has any of the emergency symptoms listed above, call your local emergency number immediately.
- If you have signs of severe dehydration (not able to keep fluids down, little urine, feeling very weak).
Book a routine appointment if:
- If you have a fever along with headache, muscle pain, and a rash, especially after traveling to a dengue-endemic area.
Diagnosis
A doctor will ask about your symptoms and recent travel. A blood test can confirm the dengue virus or the antibodies your body makes against it.
Tests that may be done
- Blood test to detect the dengue virus (PCR test)
- Blood test to check for antibodies (IgM and IgG)
- Complete blood count (CBC) to monitor platelet levels and blood thickness
What to expect at your appointment
The doctor may recommend a period of rest and monitoring. If your symptoms are mild, you will likely be sent home with advice on self-care. If you have signs of severe dengue, you may need to stay in the hospital for close observation and treatment.
Treatment
There is no specific medicine to cure dengue. Treatment focuses on managing symptoms and supporting the body while it fights the infection.
Self-care at home
- Rest as much as possible to help your body recover.
- Drink plenty of clear fluids (water, oral rehydration solution, coconut water) to prevent dehydration.
- Use paracetamol (acetaminophen) to reduce fever and pain — but avoid aspirin, ibuprofen, and other non-steroidal anti-inflammatory drugs (NSAIDs) because they can increase the risk of bleeding.
- Monitor your temperature and watch for warning signs like bleeding or severe pain.
Medical treatments
For severe dengue, hospital care is essential. Treatment includes intravenous (IV) fluids to maintain hydration, close monitoring of blood pressure and platelet counts, and supportive care for complications such as bleeding or organ damage.
When is surgery considered?
Surgery is not used for dengue. Severe complications may require procedures such as blood transfusions, but this is determined by doctors in emergency settings.
Living with this condition
Recovery from dengue can take several weeks. It is normal to feel tired and weak for a while. Gradually return to your normal activities as your energy improves, but listen to your body and rest when needed.
Lifestyle tips
- Stay indoors or use mosquito nets and repellent to avoid being bitten — dengue can be spread to others while you have a fever.
- Keep your living area free of standing water where mosquitoes can breed.
Diet and exercise
Eat light, nutritious meals (soups, fruits, vegetables) to support recovery. Drink plenty of fluids. Avoid strenuous exercise until you have fully recovered; gentle walking is fine when you feel ready.
Mental health and emotional wellbeing
The long recovery period can be frustrating or anxiety-provoking. It is normal to feel down or worried. Talk to your doctor if these feelings become overwhelming.
Prevention
Yes, the best prevention is to avoid mosquito bites. Use insect repellent, wear long sleeves and pants, sleep under mosquito nets, and remove standing water around your home.
Vaccines
There is a vaccine for dengue, but it is not recommended for everyone. It is mainly used for people who have had dengue before and live in high-risk areas. Talk to your doctor if you think the vaccine might be right for you.
Screening programmes
There is no routine screening for dengue. Prevention focuses on mosquito control and personal protection.
Complications
If left untreated
- Dengue hemorrhagic fever (bleeding, low platelets, plasma leakage)
- Dengue shock syndrome (dangerous drop in blood pressure)
- Organ damage (such as liver or heart involvement)
Long-term outlook
Most people recover fully from dengue with proper care. Severe dengue can be successfully treated in a hospital. With early medical attention and supportive care, the outlook is very good.
