Cross-sectional Serosurvey of Crimean-Congo Hemorrhagic Fever Virus IgG in Livestock, India, 2013-2014.

We conducted a cross-sectional serosurvey of Crimean-Congo hemorrhagic fever (CCHF) among livestock in 22 states and 1 union territory of India. A total of 5,636 samples from bovines, sheep, and goats were screened for CCHF virus IgG. IgG was detected in 354 samples, indicating that this virus is widespread in this country.

Systemic involvements and fatalities during Chikungunya epidemic in India, 2006.

Background: In addition to classical manifestations of Chikungunya infection, severe infections requiring hospitalization were reported during outbreaks in India in 2006.

Objectives: To describe the systemic syndromes and risk groups of severe Chikungunya infections.

Study Design: We prospectively investigated suspected Chikungunya cases hospitalized in Ahmedabad, Gujarat during September-October 2006, and retrospectively investigated laboratory-confirmed Chikungunya cases hospitalized with neurologic syndromes in Pune, Maharashtra.

Chandipura virus: a major cause of acute encephalitis in children in North Telangana, Andhra Pradesh, India.

A hospital-based surveillance was undertaken between May 2005 and April 2006 to elucidate the contribution of Chandipura virus (CHPV) to acute viral encephalitis cases in children, seroconversion in recovered cases and to compare the seroprevalences of anti-CHPV IgM and N antibodies in areas reporting cases with those without any case of acute viral encephalitis. During this period, 90 cases of acute encephalitis were hospitalized in the pediatric wards of Mahatma Gandhi Memorial (MGM) Hospital, Warangal. There were 49 deaths (Case Fatality Rate, i.

Optic neuritis associated with chikungunya virus infection in South India.

Objective: To define optic neuritis associated with chikungunya virus (CHIKV) infection in a clinical setting.

Methods: This observational case series includes 14 patients with clinical features of CHIKV infection and associated optic neuritis. Complete ophthalmic evaluations were performed, as well as other examinations, including Mantoux test, Widal test, blood profile, color vision, neuroimaging, visual fields, visual evoked potentials, VDRL test, and enzyme-linked immunosorbent assay for CHIKV-specific immunoglobulin.

Chikungunya outbreaks caused by African genotype, India.

Chikungunya fever is reported in India after 32 years. Immunoglobulin M antibodies and virus isolation confirmed the cause. Phylogenic analysis based on partial sequences of NS4 and E1 genes showed that all earlier isolates (1963-1973) were Asian genotype, whereas the current and Yawat (2000) isolates were African genotype.
