The Houston West Nile Cohort (HWNC) was founded in 2002 when West Nile virus (WNV) reached Houston, TX. The long-term outcomes following WNV infection are still mostly unknown, though neurological abnormalities up to 1 year postinfection have been documented. We report an observational study of neurological abnormalities at 1-3 and 8-11 years following WNV infection in the HWNC. We conducted st...

A recent outbreak of West Nile virus has allowed for observations as to the clinical course of this emerging pathogen during pregnancy. We present three cases of West Nile virus infection during pregnancy. Case 1 presented at term with focal subjective weakness and fever. With supportive care, her symptoms were resolved within 7 days, and she subsequently delivered an unaffected term infant. Ca...

To the Editor: After heavy rains in July 1997, extensive floods occurred along the Morava River, Czech Republic. Populations of Aedes mosquitoes increased rapidly in the flooded areas, prompting surveillance for mosquito-borne virus infections in the Breclav area, South M...

The effective reproduction number, R t , of Ebola virus disease was estimated using country-specific data reported from Guinea, Liberia and Sierra Leone to the World Health Organization from March to August, 2014. R t for the three countries lies consistently above 1.0 since June 2014. Country-specific R t for Liberia and Sierra Leone have lied between 1.0 and 2.0. R t <2 indicate that control ...

During late summer and autumn 2000, a West Nile fever outbreak in southern France resulted in 76 equine clinical cases; 21 horses died. We report the results of a large serosurvey of all equines within a 10-km radius of laboratory-confirmed cases. Blood samples were obtained from 5,107 equines, distributed in groups of 1 to 91 animals. West Nile virus immunoglobulin (Ig) G antibodies were found...

The health-care needs and resources of disease-endemic regions such as west Africa have been a major focus during the recent Ebola outbreak. On the basis of that experience, we call attention to two priorities that have unfortunately been ignored thus far: 1) the development of clinical research facilities and 2) the training of host country investigators to ensure that the facilities and exper...

We are living with a lot of diseases related to fevers different names like Chikungunya fever, West Nile rheumatic Relapsing Rat-bite fever (sodoku), Haver hill Dengue Typhoid Scarlet Viral hemorrhagic etc.

In order to laboratory confirm the first suspected West Nile fever case in 2013 in northern Greece, a combination of serological molecular and culture methods were applied. It was shown that the causative West Nile virus strain belonged to lineage 2, and possessed the amino acid substitution H249P in the NS3 protein, as in previous years. The significance of this specific strain in Europe remai...

This article analyses the on-going (2014) Ebola Virus Disease (EVD) outbreak in West Africa from a systems perspective; and draws out lessons for West Africa in general and Ghana in particular.

INTRODUCTION Estimates indicate that West Nile virus infects approximately one and a half million people in the United States of America. Up to 1% may develop West Nile virus neuroinvasive disease, in which infected patients develop any combination of meningitis, encephalitis, or acute paralysis. CASE PRESENTATION A 56-year-old African-American man presented to our hospital with headache, res...
