The ecology, genetic diversity, and phylogeny of Huaiyangshan virus in China.

Surveys were carried out to better understand the tick vector ecology and genetic diversity of Huaiyangshan virus (HYSV) in both regions of endemicity and regions of nonendemicity. Haemaphysalis longicornis ticks were dominant in regions of endemicity, while Rhipicephalus microplus is more abundant in regions of nonendemicity. HYSV RNA was found in human and both tick species, with greater prevalence in H.

Hemorrhagic fever caused by a novel Bunyavirus in China: pathogenesis and correlates of fatal outcome.

Background:  Hemorrhagic fever-like illness caused by a novel Bunyavirus, Huaiyangshan virus (HYSV, also known as Severe Fever with Thrombocytopenia virus [SFTSV] and Fever, Thrombocytopenia and Leukopenia Syndrome [FTLS]), has recently been described in China.

Methods:  Patients with laboratory-confirmed HYSV infection who were admitted to Union Hospital or Zhongnan Hospital between April 2010 and October 2010 were included in this study. Clinical and routine laboratory data were collected and blood, throat swab, urine, or feces were obtained when possible.

Hemorrhagic fever caused by a novel tick-borne Bunyavirus in Huaiyangshan, China.

Background: From April to July in 2009 and 2010, unexplained severe hemorrhagic fever-like illnesses occurred in farmers from the Huaiyangshan mountains range.

Methods: Clinical specimens (blood, urine, feces, and throat swabs) from suspected patients were obtained and stored. Mosquitoes and ticks in affected regions were collected.

[Efficacy and safety of reduced osmolarity oral rehydration salts in treatment of dehydration in children with acute diarrhea--a multicenter, randomized, double blind clinical trial].

Objective: To assess the efficacy and safety of reduced osmolarity oral rehydration salts (ROORS) in treatment of mild to moderate dehydration caused by acute diarrhea in children.

Methods: A multicenter, randomized, double-blind, positive drug controlled clinical trial was conducted in 125 cases aged 1 to 17 years. These children with acute diarrhea and signs of dehydration were randomly assigned to receive either ROORS (trial group, n = 62) or oral rehydration salts II (ORS II) (control group, n = 63).
