Although the community-based prevalence of chronic headaches with 46.2% seems to be overestimated compared to other community-based prevalence estimates for chronic headaches, e.g., the prevalence of tension-type headache in communities of northern Tanzania which was 7% during the previous year [44], a previous study from our group found a statistically significant association between Ag-ELISA seropositivity for T. solium and chronic headaches using the same screening questions than in our study [24]. The gene discussed is RENBP; the disease is Tension-type headache.
