Dengue recovery in pregnancy

Overview

Dengue is a viral illness spread by mosquito bites. During pregnancy, dengue recovery requires extra care because the infection can affect both you and your baby. Most women recover fully with proper rest and medical support.

Dengue is common in tropical and subtropical regions around the world, especially in Southeast Asia, the Americas, Africa, and the Western Pacific. In these areas, many pregnant women are at risk.

This condition affects pregnant women who live in or travel to areas where dengue is present. Any pregnant woman can get dengue, but those with a previous dengue infection are at higher risk of severe illness.

Symptoms

Common symptoms

• High fever (often up to 40°C / 104°F)
• Severe headache, especially behind the eyes
• Muscle and joint pain (sometimes called 'breakbone fever')
• Nausea, vomiting, or loss of appetite
• Tiredness and weakness
• Mild bleeding from the nose or gums, or easy bruising

Causes

Main causes

• Dengue virus – transmitted by the bite of an infected Aedes mosquito (Aedes aegypti or Aedes albopictus). The virus multiplies in the body and causes symptoms after an incubation period of 3–14 days.

Risk factors

• Living in or traveling to areas where dengue is common (tropical or subtropical regions).
• Having had a previous dengue infection – this increases the risk of severe dengue (dengue hemorrhagic fever).
• Pregnancy itself – the immune system changes during pregnancy, which can make dengue more severe.
• Being underweight or having other health conditions such as diabetes or high blood pressure.

When to see a doctor

See a doctor urgently if:

• Any of the emergency symptoms listed above (call your local emergency number immediately).
• Severe headache, abdominal pain, or vomiting that prevents you from keeping fluids down.
• Signs of bleeding – such as blood in your urine, stool, or vomit, or heavy vaginal bleeding.

Book a routine appointment if:

• If you have a fever and think you may have been exposed to dengue, see a doctor within 24–48 hours.
• If you have mild symptoms like body aches, fatigue, or a mild rash, contact your antenatal care team for advice.
• If you have been diagnosed with dengue and are recovering at home, have a follow-up appointment to ensure you are improving.

Diagnosis

A healthcare provider will diagnose dengue based on your symptoms, a physical exam, and blood tests. They will ask about your travel history and any mosquito bites.

Tests that may be done

• Blood test for dengue virus (PCR test) – detects the virus itself, usually in the first few days of illness.
• Blood test for dengue antibodies (IgM and IgG) – shows if you have a recent or past infection.
• Complete blood count (CBC) – checks for low platelets and other changes that can indicate dengue.

What to expect at your appointment

The doctor will take a small blood sample from your arm and send it to a lab. Results may take a few hours to a couple of days. You may be asked to stay in the hospital for monitoring if you have warning signs or are in your third trimester.

Treatment

There is no specific medicine to cure dengue. Treatment focuses on relieving symptoms, preventing dehydration, and watching for signs of severe illness. Pregnant women need extra monitoring to protect both mother and baby.

Self-care at home

• Get plenty of rest – your body needs energy to fight the virus.
• Drink enough fluids – water, oral rehydration solution (ORS), clear soups, or coconut water. Aim for small sips frequently.
• Take paracetamol (acetaminophen) for fever and pain. Do not take aspirin, ibuprofen, or other non-steroidal anti-inflammatory drugs (NSAIDs) because they increase bleeding risk.
• Use a damp cloth or cool bath to help lower fever, but avoid cold water or alcohol rubs.
• Monitor your temperature and symptoms daily. Keep a diary to share with your healthcare provider.

Medical treatments

If symptoms are severe, you may need to be admitted to the hospital. There, doctors can monitor your blood pressure, platelet count, and fluid balance. You may receive intravenous (IV) fluids to prevent dehydration. In rare cases, a blood transfusion may be needed. The medical team will also closely monitor your baby’s heart rate and growth.

When is surgery considered?

Surgery is not a treatment for dengue.

Living with this condition

During recovery, rest as much as possible. Avoid strenuous activity or heavy lifting. Stay in a cool, comfortable place and use mosquito nets or repellent to prevent more mosquito bites. Follow up with your antenatal clinic regularly.

Lifestyle tips

• Use insect repellent approved for pregnancy (such as those containing DEET or picaridin) to avoid further bites.
• Wear long-sleeved clothing and sleep under a mosquito net, especially during daylight hours when Aedes mosquitoes are active.
• Avoid areas with standing water where mosquitoes breed (such as flowerpots, buckets, or old tires).
• Ask family members to help with household chores so you can rest.

Diet and exercise

Eat light, nutritious meals that are easy to digest – such as soups, porridge, fruits, and vegetables. Avoid spicy or greasy foods if you feel nauseous. Do not do any exercise until you are fully recovered and your doctor says it is safe. Walking is fine once fever has gone.

Mental health and emotional wellbeing

Having dengue during pregnancy can be frightening. You may worry about your baby’s health or feel anxious and stressed. It is normal to feel this way. Talk to your partner, family, or healthcare provider about your feelings. Seek support from a counselor if you feel overwhelmed – your antenatal team can help you find one.

Prevention

Yes, dengue can be prevented by avoiding mosquito bites. There is no specific medicine to prevent dengue. Vaccines are available in some countries but are not recommended during pregnancy. The best prevention is to protect yourself from mosquito exposure.

Vaccines

A dengue vaccine exists (CYD-TDV) but is not recommended for pregnant women. Some countries may have other vaccines or research programs. Always consult your healthcare provider about vaccination before or after pregnancy.

Screening programmes

There is no routine screening for dengue during pregnancy unless you have symptoms or have been exposed. In some areas, blood tests may be offered to detect past infection.

Complications

If left untreated

• Severe dengue (dengue hemorrhagic fever) – leading to bleeding, plasma leakage, and organ damage.
• Miscarriage or preterm labor – the infection can stress the pregnancy.
• Low birth weight or other complications for the baby.
• Mother developing shock, which can be life-threatening.

Long-term outlook

With early recognition and proper care, the outlook for dengue during pregnancy is very good. Most women recover fully without lasting effects. Babies are usually born healthy, though they may need monitoring for a short time after birth. By following your doctor’s advice and resting, you give yourself and your baby the best chance for a smooth recovery.
