Seneca Valley virus (SVV) infection in pigs is associated with porcine idiopathic vesicular disease (PIVD). Outbreaks of SVV infection in pig herds have been reported in several Asia and Americas countries. Recently, a series of outbreaks of SVV infection occurred in China, Canada, Thailand and the United States. However, no available vaccines have been developed to limit the transmission of SVV....
Two-dose varicella vaccination has been available in Beijing since 2012 in the private sector. We investigated a varicella outbreak in a highly vaccinated elementary school population.A cohort study was carried out and a varicella case was defined as an acute onset of generalized maculopapulovesicular rash without other apparent cause in a student attending the school from March 29 through May 17,...
Few measles outbreaks among adults are reported in China, and outbreak response costs are seldom documented. We report an adult measles outbreak and response in 4 linked office buildings in Beijing and its associated costs.The World Health Organization measles case definitions were used to determine suspected and confirmed measles cases. Surveillance data were used to describe the outbreak, and records...
Foot-and-mouth disease (FMD) is a highly contagious vesicular disease that affects domestic and wild cloven-hoofed animals worldwide. Recently, a series of outbreaks of type A FMDV occurred in Southeast Asian countries, China, the Russia Federation, Mongolia, Kazakhstan and South Korea. The FMD virus (A/GDMM/CHA/2013) from China's Guangdong province (2013) is representative of those responsible for...
Hepatitis E virus (HEV) is a serious public health problem that causes acute hepatitis in humans and is primarily transmitted through fecal and oral routes. The major anti-HEV antibody responses are against conformational epitopes located in a.a. 459–606 of HEV pORF2. All reported neutralization epitopes are present on the dimer domain constructed by this peptide. While looking for a neutralizing...
Infectious bronchitis virus (IBV) poses a major threat to the chicken industry worldwide. In this study, we developed a recombinant fowlpox virus (rFPV) vaccine expressing the IBV S1 gene and chicken interleukin-18 gene (IL-18), rFPV-S1/IL18. Recombinant plasmid pSY-S1/IL18 was constructed by cloning chicken IL-18 into fowlpox virus transfer plasmid containing S1 gene and transfected into the chicken...
