| short report: a major genotype of japanese encephalitis virus currently circulating in japan. | a 240-nucleotide sequence of the capsid/premembrane gene region of 23 japanese encephalitis virus (jev) strains isolated in tokyo and oita, japan was determined and phylogenetic analyses were performed. all the strains clustered into two distinct genotypes (iii and i). all strains isolated before 1991 belonged to genotype iii, while those isolated after 1994 belonged to genotype i. in addition, the strains of the genotype i isolated in japan showed a close genetic relationship with those from ko ... | 2003 | 13677370 |

| natural japanese encephalitis virus infection among humans in west and east japan shows the need to continue a vaccination program. | japanese encephalitis (je) is a serious disease in asia, but it can be prevented by vaccination. to evaluate the necessity for vaccination in areas with reduced numbers of vector mosquitoes, as well as patients, it is critical to understand the frequency of natural virus exposure. an antibody survey was recently conducted to estimate current natural infection rates in japan, where the vaccination rate has dropped in recent years. serum samples were collected in 2004-2008 from inhabitants of kuma ... | 2010 | 20080072 |
| epidemics of vector-borne diseases observed in infectious disease surveillance in japan, 2000-2005. | observing the epidemics of vector-borne diseases is important. one or more cases of 6 vector-borne diseases were reported to the national epidemiological surveillance of infectious diseases in japan in 2000-2005. | 2007 | 18239342 |

| the relation between seasonal birth variation and the season of the mother's birth. | seasonal birth variation was investigated in relation to the season of the mother's birth by examining: (1) 21,517 case records of a maternity hospital in tokyo, japan, for the period between 1925 and 1960 and (2) 2,348 questionnaires on mothers and their offsprings. in general, the birth rate was the lowest in the may--july season but mothers born in may--july of 1896 through 1915 and february--april of 1916 through 1935 had their births more evenly distributed throughout the year. the less sea ... | 1980 | 7369799 |
