El Nino storms have caused major flooding in parts of Kenya's coastal regions, killing at least two people and leaving thousands homeless.The heavy rains came after a devastating drought already led to a food crisis in the east African country.
In Magarini District some communities have been without food or safe drinking water for days after a group of villages became marooned in the floods.
Dr Anisa Omar, Director of Public Health and Sanitation in Coast Region, said water-borne diseases are now a major concern.
"So far, the biggest problems we are faced with are diarrheal diseases. With all the water around we expect the mosquito population to increase and there might be an upsurge of malaria."In Kanagoni a bridge was washed away on a busy tourist road connecting the coastal towns of Malindi and Lamu.
That has led to fears that Kenya's holiday industry could suffer further in the wake of last year's post-election violence and the financial crisis.
With hundreds of homes lost, victims are making their way to three new camps.
Elvina Gabrielle, staying in one centre near Kanagoni, called on the country's leaders to send help.
She said: "I came here because the heavy rains and floods demolished our house.

"Since we've been here we've had real problems with food, bedding and medicines. I appeal to the government to come and rescue us, we have lost everything."
It isn't only people who are suffering; livestock is also being lost.
One farmer whose dead cattle littered the field around him said nearly all the animals in his village had died.
"We have had to run away and come here because nearly a thousand livestock died," he said.
With more heavy rain expected soon aid workers are focusing their efforts on getting those in danger to higher ground and preventing any further spread of disease.
The Kenyan authorities have been criticised in the past for failing to adequately prepare for floods.
Dr Omar defended the government and said the extent of the current damage could not have been predicted.
The doctor said: "When calamities come sometimes the magnitude is unexpected. In terms of dealing with diseases, I think the resources, drugs and everything were prepared."
