Effectiveness of different household water treatment approaches for people living with HIV/AIDS in Africa
conference contribution
posted on 2018-02-12, 15:09 authored by Rachel Peletz, Tom MahinAdults and children living with HIV/AIDS are more susceptible to microbiological contamination of
water. The 2008 WHO guidelines for people with HIV state that the “lack of … safe water and safe
management of human waste exposes people with HIV to increased risk of transmission of waterborne
and other enteric pathogens.” A number of different household water treatment (HWT) approaches can
potentially be used depending on local availability in a particular area. Some examples of effective HWT
are biosand filters, ceramic filters, SODIS, combined flocculationchlorination
and chlorination. For
water sources with high turbidity (seasonally or year round) the effectiveness of the HWT approach
under high turbidity conditions should be considered as part of selecting the appropriate HWT approach.
Biosand filters, ceramic filters, flocculationchlorination,
and SODIS are effective at removing or
inactivating Cryptosporidium and pathogenic bacteria commonly associated with persistent diarrhea
depending on the turbidity of the water source. Combining chlorination with a preceding turbidity and
Cryptosporidium oocyst removal step potentially provides optimal HWT for people living with HIV/AIDS.
