Isolation of recombinant type 2 vaccine-derived poliovirus (VDPV) from a Nigerian child.

A type 2 vaccine-derived poliovirus (VDPV), differing from Sabin 2 at 2.5% (22/903) of VP1 nucleotide (nt) positions, was isolated from an incompletely immunized 21-month-old Nigerian child who developed acute flaccid paralysis in 2002. Sequences upstream of nt position 620 (within the 5'-untranslated region [5'-UTR]) and downstream of nt position 5840 (in the 3C(pro) region) were derived from species C enteroviruses unrelated to the oral poliovirus vaccine (OPV) strains.

Knowledge, attitudes and perceptions of HIV/AIDS among traditional birth attendants and herbal practitioners in Lagos State, Nigeria.

Recognising the widespread role of traditional birth attendants (TBAs) and herbal practitioners (HPs) in health care at community level in Nigeria, we set out to assess their knowledge, attitudes and practices in relation to HIV infection and prevention. Questionnaires were administered to a convenience sample of 189 participants in 20 local government areas of Lagos State. We found that knowledge of modes of transmission of HIV was less than adequate and included lack of knowledge of the existence of HIV/AIDS amongst some practitioners, claims for the ability to treat HIV/AIDS, failure to name major avenues of transmission and confusion of HIV/AIDS with other conditions.
