measles virus strains circulating in central and west africa: geographical distribution of two b3 remains one of the major reservoirs of measles infection. molecular epidemiological studies have permitted different measles virus isolates to be grouped into clades and genotypes; the major group, which has been identified as indigenous to africa, is clade b. the viruses from epidemics in the gambia (1993) and in the cameroon (2001) were examined. in both studies, the homogeneity of the virus isolates within the epidemic as shown by sequence analysis revealed less than 0.2% variation of ...200212226833
