Cholera outbreak in Nigeria kills six people

According to health officials, a fresh cholera outbreak in northern Nigeria has killed six people, raising the overall death toll in the country to over 200 people in recent months.
The most recent outbreak was recorded in the Kebbi state town of Koko, AFP reports.
"We have recorded six deaths from cholera in Koko in the past two weeks that infected 182 people," Shehu Sambawa, the state's health commissioner said, according to AFP.
Approximately 70 people have died of cholera in under two months in the state. Nigeria's senate launched an investigation Thursday into the recurring cholera epidemics, stating that 234 people have died in 15 of the country's 36 states so far this year.
Cholera outbreaks occur regularly during the rainy season in Nigeria, when downpours wash contaminants into wells used by families. The rainy season usually runs from April to September.
According to the Centers for Disease Control and Prevention, cholera is an acute, diarrheal illness that is caused by infection of the intestine with the bacterium Vibrio cholerae. There are an estimated three to five million cases with more than 100,000 deaths each year around the world. While the infection is often mild or without symptoms, approximately one in 20 people will become severely infected and, without treatment, death can occur from dehydration and shock within hours.
