Staying healthy during the rainy season in Dakar

Dakar's rainy season, known locally as the hivernage, runs from July to October and peaks in August and September. A single downpour can turn a street into a pond, and that standing water is exactly where mosquitoes breed. Here are the habits that actually protect a family, a newcomer or a diaspora visitor. This article is informational only: for any symptom, consult a healthcare professional.

Mosquitoes and malaria come first

The malaria mosquito bites mainly at night, between sunset and sunrise. Numbers surge after the rains, especially in low lying, poorly drained areas such as Parcelles Assainies, Pikine, Guediawaye, Keur Massar and parts of Rufisque. Coastal neighborhoods like Almadies, Ngor and Yoff get more wind, but no one is immune.

• Sleep under a treated bed net, above all for children and pregnant women. Expect roughly 3,000 to 8,000 FCFA depending on the model.
• Fit or repair window screens. A fan moving air across the room also makes it harder for mosquitoes to land.
• Apply a skin repellent in the evening on ankles and arms, following the packaging instructions.
• Empty anything that holds water: plant saucers, tires, buckets, blocked gutters, tarpaulins. One forgotten puddle can produce hundreds of mosquitoes.

If a fever appears during or after the season, do not guess. A rapid test at a health facility gives an answer quickly. Consult a healthcare professional, especially for a child, a pregnant woman or an older person.

Floodwater: what to avoid

After heavy rain, the water sitting in the street is not clean rainwater. Where drainage is overwhelmed, it mixes with wastewater.

• Never wade barefoot through floodwater. Boots or closed sandals beat flip flops.
• Wash feet and legs with soap when you get home, and clean any open cut properly.
• For drinking, prefer bottled or filtered water. A pack usually runs 2,000 to 4,000 FCFA, a household filter 15,000 to 60,000 FCFA.
• If you store water, keep containers covered. An open drum is a larvae nursery.

Stomach bugs rise sharply in this period. In a young child, dehydration moves fast: fewer wet diapers, unusual drowsiness or refusing to drink are reasons to seek care straight away.

Humid heat, skin and breathing

The hivernage also brings heavy humidity. Across Plateau, Point E, Mermoz and Sacre Coeur, apartments feel clammy and walls show damp patches.

• Drink regularly even without thirst, and avoid hard physical effort in the hottest hours.
• Dry skin folds carefully after showering, since humid heat encourages fungal irritation and heat rash.
• Air out rooms daily and wipe away damp, which bothers people with asthma or allergies.
• Check supplies of any long term treatment before the peak weeks, when getting around is harder.

Food hygiene and children

Heat plus humidity spoils food faster than most newcomers expect.

• Wash fruit and vegetables with clean water, and peel what can be peeled.
• Do not leave a cooked dish at room temperature. Past about two hours, throw it away.
• After a long power cut, be cautious with meat and fish that sat in the freezer.
• With street food, pick a stall where cooking happens in front of you and meat is served piping hot.
• Teach children to wash their hands after school, before eating and after the toilet.

The season overlaps with the school year starting, so colds, sore throats and stomach bugs travel quickly through classrooms. Check that vaccination records are up to date and keep a household kit ready: thermometer, soap, hand sanitiser, plasters, a spare bed net. For anything involving doses or treatment, ask a pharmacist or a doctor.

Keep the official numbers in mind: Police 17, Fire and rescue 18, SAMU 1515. Identify the nearest health facility before you need it, because a familiar trip can take twice as long under heavy rain.
