Incidence of Alpha-Herpes virus induced ocular disease in Suriname.
Herpes simplex virus (HSV) infection of the corneal stroma is the most prominent cause of scar formation impairing visual acuity and HSV keratitis is the leading cause of corneal opacity throughout the world. Suriname lacked test systems for microbial causes of ocular disease, therefore a polymerase chain reaction-based Herpes virus assay was introduced, enabling prompt recognition, and timely treatment, preventing progressive eye damage. The incidence and epidemiology of Herpes simplex virus type 1 (HSV-1), type 2 (HSV-2), and varicella zoster virus (VZV) in ocular disease in Suriname was assessed. In a cross-sectional prospective study, ocular swabs were collected from 91 patients with a presumptive α-Herpes virus ocular infection attending the Academic Hospital between November 2008 and August 2010 and were tested by a PCR-based α-Herpes virus assay. Alpha-Herpes virus ophthalmic infections were caused predominantly by HSV-1 with a prevalence of 31%. The prevalences of VZV, HSV-2, and a mixed HSV-1/HSV-2 infection were 4%, 3%, and 2%, respectively. The first reported annual incidence of herpetic induced ocular disease in Suriname was estimated at 11.4 per 100,000 person-years (95% CI, 4.8-18.1). No clear age, ethnic or gender dependent difference in incidence was observed. The information obtained on α-Herpes virus positive ocular infections and the distribution of subtypes provided the first insight in the South American situation of α-Herpes virus induced ocular disease.
