Ghana’s Flood Crisis Is a Public Health Crisis!

Prof. Victor Wutor

The water came, and so did the sickness. The rain may stop, but the danger does not!

When floods hit Ghana’s low-lying communities, they do more than destroy roads and homes. They invade lives. They contaminate water sources, overwhelm sanitation systems, displace families, and create the perfect conditions for cholera, malaria, typhoid, and other infectious diseases. And with the Ghana Meteorological Agency warning that the 2026 rainy season could intensify flooding, this is no longer a distant concern. It is a warning we ignore at our peril.

That warning should be treated as a public health alarm, not a routine weather update.

We have already seen what happens when floodwaters are allowed to linger. The Akosombo flood disaster of 2023 displaced an estimated 35,857 people and submerged farms, houses, and communities in the lower Volta basin. WHO later warned that the flooding and displacement heightened the risk of outbreaks of cholera, malaria, and other diseases. The lesson is clear: the flood is not the end of the crisis. It is the beginning.

While NADMO counted houses, hospitals counted something else: fevers, rashes, coughs, and fear.

Floodwater does not come empty-handed. It carries disease.

Ama learned that the hard way. She did not fall ill the day her sewing machines floated away. She got sick six days later, after wading through Circle’s brown floodwater to recover what she could. A small cut on her leg never healed. It became red, swollen, and hot. The nurse gave the diagnosis: leptospirosis — a disease linked to rat urine in floodwater.

Ama is not alone. Across Kaneshie, Odawna, Weija, Adentan-Dodowa, Darkuman Junction, and Adabraka, health workers are seeing the same pattern: more skin infections, more wounds that won’t heal, more fevers that cannot be explained without laboratory tests.

And in Anloga, the crisis has taken another form. Two thousand one hundred and forty-six acres of farms are under water. Okro is gone. Tomatoes are gone. But the water remains. And where standing water remains, mosquitoes breed.

“We know what comes next,” a nurse at Anloga Health Centre said. “Two weeks after the flood, the malaria cases double. The children come in shaking.” Nine thousand five hundred children are sleeping on wet classroom floors in Anloga right now. Their mothers are doing everything they can to keep them dry, but cloth cannot stop a mosquito.

This is why Ghana must stop treating floods as isolated emergencies and start treating them as the public health crises they are.

We need prevention, not just reaction.
First, public health planning must be built into flood preparedness. Flood-prone communities need early warning, protection of clean water, sanitation support, disease surveillance, and rapid access to treatment supplies. WHO and Ghana’s partners have already shown that this approach works, especially after the Akosombo floods.

Second, flood response must reach the communities most exposed: informal settlements, low-lying neighbourhoods, displaced families, and areas with weak sanitation systems. Flooding does not strike evenly. It lands first and hardest on the poor.

Third, Ghana must invest in vaccines and prevention tools now, not after the outbreak begins. Cholera, typhoid, hepatitis A, and malaria are not surprises after flooding. They are predictable consequences. Predictable disease demands bold prevention.

We cannot stop the rain in 2027. But we can stop the sickness that comes with it.

That means urgent vaccination in high-risk communities now, before the next rains, and immediately after flood events where needed. Priority areas should include communities within 1km of the Odaw, Korle Lagoon, Volta Riverbanks, Anloga Lagoon, Samraboi streams and the like.

The response should include:

1. Oral Cholera Vaccine (OCV) — two doses, with about three years of protection.
2. Typhoid Conjugate Vaccine (TCV) — one dose, with long protection for children and adults.
3. Hepatitis A Vaccine — for traders, camp residents, and market zones where food and water mix.
4. Malaria Vaccine (RTS,S or R21) plus nets — to protect Anloga, Volta, and Accra’s flood suburbs before mosquito numbers surge.
5. Routine catch-up vaccination — measles, polio, and rotavirus for the 9,500 children in Anloga whose clinics were cut off.

A dose of OCV costs less than a bottle of water. One week of treating a cholera outbreak costs more than vaccinating an entire community.

Between now and September 2026, Ghana should launch emergency OCV and TCV campaigns in camps and flooded communities. From October 2026 to March 2027, dry-season door-to-door campaigns should reach at-risk households. Then, before the rains return in April and May 2027, there must be a final push to protect children, pregnant women, and the elderly.

Ghana’s flood response must act on six fronts:

1. Protect people. Stop building in waterways. Relocate with dignity.
2. Rebuild systems. Build drains for 150mm of rain and keep clinics above flood lines.
3. Restore nature. Bring back wetlands. Give water room.
4. Warn early, vaccinate early.
5. Deploy trained community-based volunteers to screen for disease and report symptoms.
6. Deliver care. Fast, transparent relief with doctors, pharmacists, nurses, nets, and vaccines.

Flooding in Ghana is no longer just a matter of property loss. It is a recurring threat to maternal health, child health, sanitation, and disease control.

Ghana still has a choice: act before disease spreads or keep mourning after the damage is done.

The next flood will come. That is certain. What is not acceptable is the next round of excuses.

Ghana does not need another disaster to prove the point. It needs political will — now. Before the water rises. Before the wards fill. Before preventable illness becomes preventable death.

This is the truth we can no longer ignore: floods are not only a climate issue. They are a health security emergency. And if we wait until cases rise in clinics, we have already waited too long!
