In a context of shortage of drinking water following a persistent drought in Mayotte, the High Council for Public Health (HCSP) decides on the advisability of implementing vaccination campaigns in this territory once morest four infections linked to the faecal: cholera, typhoid fever, hepatitis A and poliomyelitis.
After an analysis of the epidemiological situation, the vaccination coverage and the interest of carrying out vaccination campaigns given the situation, the HCSP considers that despite the shortage of drinking water on the territory of Mayotte, the The current epidemiological situation on the island for cholera, typhoid fever, hepatitis A and poliomyelitis does not justify a vaccination campaign in anticipation of the entire population of Mayotte once morest these 4 diseases. For typhoid fever alone, targeted early vaccination might be offered to inhabitants of areas with unsanitary housing and high incidence (> 100 cases/100,000 inhabitants).
Although the risk of reintroduction and epidemic of cholera and that of occurrence of cases of poliomyelitis is low, the HCSP recommends setting up environmental monitoring of wastewater to detect early the possible circulation of cholera vibrio and poliovirus. This environmental surveillance and the strengthening of health monitoring in place in the territory of Mayotte will make it possible to detect early the appearance (cholera, poliomyelitis) or a resurgence (typhoid fever, hepatitis A) of cases. If necessary, the vaccine response strategy will be defined in real time, depending on the epidemiological situation.
For these 4 diseases, it is therefore necessary to ensure that sufficient stocks of vaccines are pre-positioned on the territory.
