The Ghana Health Service (GHS) has issued a public advisory warning residents to prepare for health risks associated with the onset of the rainy season.

In a press release signed by the Director-General, Dr Samuel Kaba Akoriyea on May 29, 2026, the Ministry of Health, through the GHS, said early rains following prolonged dry periods commonly trigger a rise in waterborne illnesses such as typhoid, cholera and dysentery.

The agency explained that rainwater can wash contaminated faecal matter into water sources, increasing the risk of infection as vegetables grown near water bodies may also become contaminated.

The GHS further warned that the rains create breeding grounds for mosquitoes, heightening the threat of mosquito‑borne diseases including malaria, yellow fever and dengue fever.

Common breeding sites include stagnant water in discarded containers such as cans and old tyres.

Officials urged members of the public to take simple preventive measures to reduce the risk of outbreaks.

Recommended actions include keeping surroundings clear of containers that can collect water, clearing bushes around homes, ensuring foods are thoroughly cooked, and washing fruits and vegetables with clean water and salt or vinegar.

People should buy food only from hygienic, reputable sources and wash their hands regularly with soap under running water, particularly before handling food.

The GHS advised anyone who develops symptoms to report promptly to the nearest health facility.

The advisory also sets out guidelines for food vendors, calling on them to source ingredients from approved suppliers, follow strict food‑safety practices during preparation and storage, keep raw and cooked foods separate, thoroughly wash produce, and ensure food‑handling certificates are valid.

The statement warned that heavy rains may cause flooding, which can displace reptiles and increase human contact with such animals.

Residents were advised to keep doors and windows closed where possible, raise belongings off the floor, and clear bushes and holes around compounds to reduce hiding places.

The GHS reaffirmed commitment to protecting public health and appealed for community cooperation to prevent disease outbreaks during the rainy season.
