Summary: Since the last week of December 2010, several localities of the Republic of Gabon have been facing violent wind and torrential rains. The situation deteriorated in early January 2011 as the Tchimbanga, Franceville, Mimongo and Dzenzele localities experienced serious torrential rains and violent wind, leading to massive destruction of houses and other considerable damages. On 2, 3 and 4 January, 2011 serious violent wind and torrential rains caused flooding and the destruction of houses and other household property in the above-mentioned localities. The disaster affected 353 families, i.e. 1,765 people, claimed one death in Tchimbanga and wounded many in all four localities. Moved by the scope of the disaster, the volunteers of the Gabonese Red Cross Society (GRCS) conducted an emergency evaluation of the situation and identified 203 families, i.e. 1,015 people, as the most vulnerable. These are people that have been left homeless, with no household property. They are living in the open air under extremely precarious conditions as it continues to rain. They are currently exposed to the risks of water borne diseases and other weather-based diseases such as respiratory infections. The most vulnerable people identified by the Red Cross include 197 children below five years, 32 pregnant women, 201 old people and four disabled persons.
