Objective: To study the lineages of rabies virus and the epidemic characteristics in different provincial populations of China, to provide information for the development of control and prevention measures in each respective provinces. Methods: Full length N and G genes and full-genome of epidemic strains of rabies virus collected in China were downloaded from GenBank and combined with newly sequenced strains by our lab. Each strain was classified under six lineages of China rabies by constructing phylogenetic trees based on the N or G sequences. Numbers of strains and lineages in each province were counted and compared. Results: Six lineages (China Ⅰ-Ⅵ) were prevalent in China, with 4 found in Yunnan and Hunan. In 6 provinces, including Henan and Fujian, 3 lineages were found. In 8 provinces, including Shanghai and Jiangxi, 2 lineages were found Only 1 lineage, were found in Beijing, Tianjin and other 12 provinces. the China Ⅰ, was the dominant one in 25 provinces. In recent years, China Ⅲ had been found in wild animals and spread over livestock in Inner Mongolia and Xinjiang areas. Qinghai and Tibet had been influenced by China Ⅳ, which also been found in wild animals of Inner Mongolia and Heilongjiang. Conclusion: There had been obvious differences in lineages and strain numbers of rabies virus identified in different provinces in China.

The number of human rabies cases acquired from dog bites constitutes a high proportion of the total rabies cases in China, although the number of human rabies cases has gradually decreased in recent years. The pivotal role of dogs in the spread of rabies indicates that controlling and preventing canine rabies could be a key step in eradicating human rabies in China. The primary aims of this review are to discuss the properties and pathogenesis of the rabies virus, the clinical signs and diagnosis of canine rabies, threshold host density and vaccination of dogs, and the prevention and control of canine rabies in China.

OBJECTIVETo summarize and analyze the epidemic situation of human rabies from 1984 to 2002 in China, and to explore the possible factors causing the increase of cases so as to provide evidence for preventive and control measures.

METHODNational and some provincial data on the prevalence of rabies during 1984 to 2002 were collected and analyzed.

RESULTSFrom 1984 to 1989, the annual reported cases were between 4 000 and 6 000 but decreased after 1990. In 1996, the reported cases decreased to the lowest level from 3 520 in 1990 to 159. However, number of reported cases has been continuously increasing since 1998 which reached 1 122 in 2002, a 7.06 times increase as compared to the number in 1996. The epidemic areas were mainly located in the southeast and southwest parts of the country, such as Sichuan, Hunan, Guangxi, Guangdong, Anhui, Fujian, etc. Furthermore, there was no significant seasonal distribution as it showed before.

CONCLUSIONSuch facts as the increasing numbers of dogs, low inoculation rate to dogs, poor control on the quality of rabies vaccine, mistreatment to the wounds, and lacking good cooperation between different official departments regarding rabies control might serve as important factors responsible for the recurrence of rabies. Therefore, it is necessary to focus on the above mentioned points and to take comprehensive preventive measures to bring down the prevalence of rabies in China.

OBJECTIVETo study the epidemic intensity and trend of human rabies from 1991 to 2005 among 31 provinces, metropoli and municipalities in China so as to increase the awareness of the disease.

METHODSContrastive analyses were performed and the annual publishing data by the Chinese Center for Disease Control and Prevention were used.

RESULTSThe total number of reported cases was 14 942 from 1991 to 2005 with an annual average mortality rate as 0.080/100000. The increase of five-years mortality ratio on relative ratio with circular base of mortality rate were--66.24% (1996-2000 to 1991-1995) and 506.13% (2001-2005 to 1996-2000). When comparing incidence rates between 2000-2005 and 1991-1995, the relative ratio with fixed base increase became 104.62%.

CONCLUSIONAmong the 31 provinces, metropolis and municipalities, 27 had reported human rabies cases. The enzootic areas mainly distributed in the drainage area along the Yangtze River. The incidence rates of Guangxi, Hunan, Guizhou, Jiangxi and Guangdong were the highest.

Rabies remains a continuous threat to public health in Beijing. In this study, a total of 224 brain tissues were collected from suspected infected stray dogs within Beijing between January 2015 and December 2016. Among them, total of 67 samples were diagnosed positive for rabies. In the phylogenetic analysis, rabies in Beijing is currently a relatively independent public health issue originating from local rabid dogs apart from the imported cases from elsewhere in the country. Because vaccination of unregistered dogs against rabies is still neglected in Beijing and other regions of China, national and local authorities should play central roles in all related aspects, such as development of policies, engagement of stakeholders for public and professional education, entire vaccination process, and animal management.

OBJECTIVETo analyze 21 cases of rabies from February 8 to May 1 in 2004 in Anlong county in Guizhou province, and to explore the possible factors causing the epidemics.

METHODS21 cases of rabies were investigated. The canine brains were collected, and indirect immunofluorescence assay was used to detect rabies virus antigen in the brains.

RESULTSFrom February 8 to May 1st in this year, 21 cases of rabies were reported, with 5.12/100,000 of the prevalence rate. Dogs accounted for 20 cases, and cat for one case. Median incubation period was 36.52 days, but less than 15 days in 6 cases. Among 21 cases, 17 cases were not correctly treated, and 9 cases received vaccine, with 3 cases vaccinated in time. No cases received passive immunization of antirabies serum or human antirabies immune globulin. A total of 73 dogs' brains were examined for rabies viral antigen by IFA, and 9 (12.33%) were positive.

CONCLUSIONThe increasing number of dog, high rate of virus carrier in dogs, incorrect treatment of the wound, and as well as low inoculating rate of rabies vaccine might be responsible for the outbreak of rabies in Anlong county.

OBJECTIVETo analyse the related epidemic factors of rabies and to provide basic evidence for developing rabies control and prevention programs in China.

METHODSPossible factors that causing rabies epidemics in the southern part of China were obtained through collecting both epidemic and surveillance data of rabies in 2005, and to analyse every factor by software of Excel 2002.

RESULTSThe number of rabies cases was 2548 in 2005. Among 885 cases being investigated, 60.56%, 49.04%, 96.16% had not had any chance to receive treatment, vaccine or immunoglobulin. Among the exposed persons, 89.95% received treatment on wounds and 94.93% were immunized, and 8.56% received immunoglobulin. 94.86% of them accomplished the full rabies post-exposure prophylaxis course, but 8.56% of them did not accomplish it. 88.50% of the cases and 92% of the persons under exposure were bitten by dogs. The density of dogs was 3.20-13.37 per 100 persons. The vaccination coverage rates among dogs were 5.31% -75.11% with a positive rate of 2.93 % -6.40%.

CONCLUSIONFactors as: low rate of post-exposure prophylaxis and failed to have finished the necessary post-exposure treatment (PET) of the cases, nonstandard PET in hospital or local clinic, low rabies vaccination coverage and high infectivity of rabies virus in animal host (mainly for dog) might be responsible for rabies epidemics in China, in 2005.
