Text

A minor error was found in Table 1 that described and compared the demographics amongst all participants, cases, controls and mono-infections after publishing this work [1]. For recruits, the number and the corresponding proportion in each group was under-reported. This was caused by discrepancies in the database in how recruits were coded that were not noticed until now. We have recoded recruits in the database and have re-analysed data. The differences in proportions of recruits amongst all groups remained significant with the revised data (Table 1). These errors only affect this table. All the other results and conclusions remain.
