Improving dog bite victim survey and estimation of annual human deaths due to suspected rabies cases in three selected Liberian cities and environs, 2008-2017.

Rabies remains a public health challenge of unknown magnitude in Liberia in spite of the goal of ensuring that no human in the country dies of rabies by 2030. The annual prevalence of Dog Bite Victims (DBVs) and true load of Annual Human Deaths (AHDs) due to rabies were not known. We investigated three selected cities of Liberia for annual prevalence of DBVs and true load of AHD due to suspected rabies, using 10-year retrospective record, 2008-2017 obtained from Buchanan, Gbarnga, and Voinjama, three socio-economically important cities in post-conflict Liberia.

Syndromic survey and molecular analysis of influenza viruses at the human-swine interface in two West African cosmopolitan cities suggest the possibility of bidirectional interspecies transmission.

Influenza viruses are frequently transmitted between pigs and their handlers, and among pig handlers. However, reports on socio-environmental variables as potential risk factors associated with transmission of influenza in West African swine production facilities are very scarce. Syndromic survey for influenza was therefore conducted in Ibadan, Nigeria, and Kumasi, Ghana, in order to identify and elucidate selected socio-environmental variables that may contribute to the occurrence and distribution of influenza-like illness (ILI) among swine industry workers.

Detection of pandemic strain of influenza virus (A/H1N1/pdm09) in pigs, West Africa: implications and considerations for prevention of future influenza pandemics at the source.

Background: Human and animal influenza are inextricably linked. In particular, the pig is uniquely important as a mixing vessel for genetic reassortment of influenza viruses, leading to emergence of novel strains which may cause human pandemics. Significant reduction in transmission of influenza viruses from humans, and other animals, to swine may therefore be crucial for preventing future influenza pandemics.

Prevalence of antibodies to influenza viruses among handlers of live pigs at three locations in Ibadan, Nigeria.

The authors investigated the prevalence of haemagglutination inhibition (HI) antibodies to four strains of influenza viruses among handlers of live pigs in Ibadan, Nigeria. Venous blood specimens were collected from thirty pig handlers (out of a total of forty-eight) at three locations in Ibadan in April and May 2008. The overall prevalence of antibodies to influenza viruses was 100%, while those of influenza A and B viruses were 68.

Isolation of influenza A viruses from pigs in Ibadan, Nigeria.

The authors investigated influenza virus types in pigs in Ibadan, a city in Oyo State, south-western Nigeria. From April to June 2008, nasal swabs were collected from pigs at three locations in Ibadan. Influenza A viruses (four A [H1N1], two A [H3N2] and one A [H1N1]-A [H3N2] double reactant) were isolated from 7 of the 50 apparently healthy Landrace pigs tested.

Antibody levels against rabies among occupationally exposed individuals in a Nigerian University.

The authors investigated the levels of anti-glycoprotein antibodies against rabies virus in the sera of occupationally exposed humans at the University of Ibadan, Nigeria. A quantitative indirect enzyme-linked immunosorbent assay (ELISA) was used to detect rabies virus anti-glycoprotein antibodies in sera from 20 zoological garden workers, 20 veterinarians and 30 clinical veterinary students at the University of Ibadan. The sera were obtained between September 2008 and February 2009.
