Dengue virus (DENV) causes fever and severe haemorrhagic symptoms in humans. The DEN2 16681 strain, derived from a dengue haemorrhagic fever patient, has been widely used in studies related to DENV pathogenesis, such as mouse and non-human primate haemorrhagic models and human vascular endothelial-cell permeability. To clarify the entry mechanism of the(More)
Among the tick-borne orbiviruses (genus Orbivirus, family Reoviridae), 36 serotypes are currently classified within a single virus species, Great Island virus. In this study, we report the first characterization of a tick-borne orbivirus isolated from the tick Ixodes turdus in Japan, which we identified as a new member of the species Great Island virus. The(More)
Dengue is the one of the most prevalent arthropod-borne viral diseases. Dengue virus circulates between humans and mosquitoes, and causes a wide range of disease in humans. To elucidate the link between the cell tropism of dengue virus and its pathogenesis, peripheral blood cells of infected patients were analyzed by flow cytometry. The dengue virus antigen(More)

Hepatitis A virus (HAV) is one of the most common causes of feces-transmitted acute hepatitis worldwide. In Japan, most of HAV infections have been sporadic cases and a relatively low number of cases (approximately 100-150) of acute hepatitis A were reported in 2012 and 2013. However, in 2014, 342 cases were reported as of week 22. In order to characterize(More)
In recent years, there has been an increase in the number of reported hepatitis E virus (HEV) infections from developed countries. To describe recent trends in notification and potential risk groups and risk factors in Japan, HEV infection cases and demographic, food consumption, clinical and laboratory data reported during 2007-2013 were analysed.

BACKGROUND Dengue is becoming an increasing threat to non-endemic countries. In Japan, the reported number of imported cases has been rising, and the first domestic dengue outbreak in nearly 70 years was confirmed in 2014, highlighting the need for greater situational awareness and better-informed risk assessment. METHODS Using national disease(More)

Measles is a highly contagious disease causing an estimated 2.6 million deaths per year before a vaccine was developed. However, the attenuated measles vaccine has brought the disease under control. Vaccine-associated measles can occur in children and immunocompromised individuals. Little is known about the occurrence of vaccine-associated measles in(More)
