SEROPROTECTION RATE OF HAEMOPHILUS INFLUENZAE TYPE B CONJUGATE VACCINE AND ASSOCIATED CLINICAL OUTCOMES AMONG NIGERIAN CHILDREN AGED 6 TO 23 MONTHS.

Introduction: Haemophilus influenzae type b (Hib) causes invasive infections almost exclusively in under- fives with those aged 6-23 months being the most vulnerable. In Nigeria, it is estimated to cause nearly 400,000 annual infections and another 30,000 under-five mortality attributable to pneumonia and meningitis alone. The Hib Conjugate Vaccine (HCV) is in widespread use to combat these devastating infections.

Characterization of transboundary foot-and-mouth disease viruses in Nigeria and Cameroon during 2016.

Continuous surveillance for foot-and-mouth disease (FMD) in endemic settings such as West Africa is imperative to support improved local and regional control plans, with the long-term goal of regional eradication. This paper describes the genetic characterization of FMD viruses (FMDV) obtained from outbreaks in Nigeria (n = 45) and Cameroon (n = 15) during 2016 and from archival samples (n = 3) retrieved from a 2014 outbreak in Nigeria. These viruses were analysed in the context of previously published FMDV sequences from the region.

Serological and molecular epidemiology of foot-and-mouth disease viruses in agro-pastoralist livestock herds in the kachia grazing reserve, Nigeria.

The Kachia Grazing Reserve (KGR) is located in Kaduna state in north-western Nigeria and consists of 6 contiguous blocks housing 744 defined households (HH), all engaged in livestock keeping. It is considered as a homogenous epidemiological unit and a defined study area. In 2012, all cattle and sheep of 40 selected HH were sampled to determine sero-prevalence of antibodies to foot-and-mouth disease virus (FMDV) and of FMDV.
