[Impact of market place activity on the spread of STI/AIDS in Sikasso, Mali]. / Impact des fêtes foraines dans la propagation des IST/sida à Sikasso au Mali.

Since the beginning of the global HIV pandemic, more than 47 million people have been infected and more than 14 millions of people have died with 95% living in developing countries. Mali is located in West Africa that has been relatively less affected. However Mali is a country with a migratory culture. This study was conducted in primary health care centers located on the main road to neighboring countries with higher HIV prevalence. Attention was focused on healthcare services provided around market places in the main cities where diverse populations converge on a weekly basis. Attendance measured at five health centers on market day was compared with attendance on the other days of the week. In addition the level of sexually transmitted infections (STI) diagnosed on market days was determined to compare prevalence in the resident versus non-resident population in function of market activity. Attendance at all the centers was significantly higher on market days. This increase was due mainly to the non-resident population (60.2% vs. 46.5%; p=0.005). Findings also showed that the proportion of STI diagnosed was higher in the non-resident than resident population, but the difference was not statistically significant (15.6% vs. 11.3%; p=0.320). These results indicate that migration has an impact on the spread of STI. This is probably the same for HIV since these pathologies are known to be linked. Control strategies to fight against STI/AIDS could be improved by taking into account market place activity that is common in all localities of Mali and Africa.
