Preventing Mosquito-Borne Diseases During Pregnancy

Mosquito-borne diseases are infectious diseases that spread through the bite of a mosquito that carries the infection-causing agent. Your risk of infection greatly depends on where you live or travel. Pregnancy requires extra care because some of these infections can have serious consequences for the mother or pregnancy.

Dr Sadhna Singhal Vishnoi, Associate Director – Department of Obstetrics and Gynaecology at Cloudnine Group of Hospitals, Punjabi Bagh, New Delhi, explains why reducing mosquito exposure is important during pregnancy and how you can protect yourself.

Certain simple precautions may help you lower your risk by avoiding mosquito bites and reducing mosquito breeding around your home.

Why Is It Important To Take Extra Precautions During Pregnancy?

Pregnancy itself does not increase your risk of mosquito bites. However, certain mosquito-borne infections may affect your health. Such effects may impact your pregnancy or the health of the developing baby.

According to Dr Sadhna Singhal Vishnoi, mosquito-borne diseases may cause serious complications for the mother or the pregnancy. These diseases may include:

Dengue
Malaria
Chikungunya
Zika

Therefore, prevention should begin with minimising mosquito exposure and eliminating mosquito breeding grounds. This is the most important measure, especially in areas where these infections are predominant. Some infections may cause fever, dehydration or other complications. Zika infection can also affect foetal development.

How Can You Prevent Mosquito Bites During Pregnancy?

Dr Sadhna Singhal Vishnoi recommends using an insect repellent considered safe during pregnancy and following the product instructions. You can also:

Wear loose, long-sleeved shirts and long trousers
Choose permethrin-treated clothing where appropriate; do not apply permethrin directly to your skin
Stay in places with window screens or air conditioning
Sleep under an insecticide-treated mosquito net, particularly in malaria-endemic areas
Avoid unnecessary outdoor exposure when mosquitoes are most active, where practical

Are Mosquito Repellents Safe During Pregnancy?

Many pregnant women worry about using insect repellents. EPA-registered repellents are considered safe and effective during pregnancy when used according to the product label.

Commonly recommended active ingredients include:

DEET
Picaridin (Icaridin)
IR3535
Oil of lemon eucalyptus (OLE) or para-menthane-diol (PMD)
2-undecanone

If you use sunscreen, apply it before the insect repellent. Always follow the product instructions.

How Can You Reduce Mosquitoes Around Your Home?

Mosquitoes can breed in stagnant water. Dr Sadhna Singhal Vishnoi recommends regularly removing or emptying water from containers around your home and keeping water-storage containers properly covered.

Preventive measure	Why it helps
Empty water from buckets, coolers, pots and trays	Prevents mosquito breeding
Cover water-storage containers	Reduces mosquito access to water
Clean gutters and drains	Prevents stagnant water collection
Repair window and door screens	Helps keep mosquitoes outside
Use air conditioning where available	Reduces indoor mosquito exposure
Keep surroundings clean	Minimises potential breeding sites

Keep checking the containers regularly where rainwater may collect and become stagnant, especially during the rainy season.

What Precautions Should You Take While Travelling?

If you are pregnant, Dr Sadhna Singhal Vishnoi advises you to stay aware of local disease outbreaks. Also, follow public health advisories when travelling.

Before travelling:

Check whether mosquito-borne diseases are circulating at your destination
Discuss your travel plans with your healthcare provider
Carry an appropriate insect repellent
Choose accommodation with screened windows or air conditioning
Use an insecticide-treated mosquito net (where adequate protection is unavailable)
Wear protective clothing outdoors

Travel to areas with active transmission of certain mosquito-borne infections may require additional precautions or, for some diseases, reconsideration of travel.

When Should You Contact Your Doctor?

Dr Sadhna Singhal Vishnoi recommends prompt medical care if you develop concerning symptoms during pregnancy, particularly after significant mosquito exposure or travel. These may include:

Fever or chills
Severe headache
Body aches
Rash
Unexplained bleeding
Persistent vomiting

You should inform your doctor about recent travel or mosquito exposure. It is advised not to self-medicate for fever during pregnancy without consulting your doctor.

A combination of personal protection, environmental control and timely medical care can substantially reduce mosquito exposure during pregnancy.
