Infection is transmitted to humans by Ixodes tick-bite, and causes a disease affecting skin, nervous system, heart, and joints. Recent studies in Mexico documented cutaneous clinical cases infected with B. burgdorferi and ticks from the Northeast of the country infected with B. burgdorferi sensu stricto. Aim: To document Borrelia infection in patients with suggestive Lyme disease in Central of Mexico, and to search for the presence of B. burgdorferi-infected competent vectors and reservoirs. Methods: We studied 800 patients suggestive of Lyme disease in one Pediatric and one General hospital. Sera, biopsies, and cerebrospinal fluids were tested for infection using immunological, microbiological, and molecular test. Ticks and mice were collected in forest areas, which patients visited, and infection studied by culture and molecular tests. MEXICAN PATIENT WITH EM Results: From 800/136 cases (17%) fulfilled the CDC criteria confirming B. burgdorferi infection, 88 adults (64.5%) and 48 children (35.5%). Eighty-one presented neurological manifestation (59.6%), 45 cutaneous lesions (33%), and 10 arthritis (7.4%), and 68 reported previous tick exposure (50%). Thirty-six Peromyscus sp. and 17 Neotomodon alstoni mice were collected in forest areas; five P. melanotis were found infested with Ixodes spinipalpis ticks. In 16 mice, samples from bladder and articulation were tested; five were culture+ and seven PCR+ for fla and ospA genes. Amplified fla and ospA genes from clinical, rodent and tick samples were sequenced and confirmed as Borrelia burgdorferi sensu stricto genes. Ixodes spinipalpis tick infesting Peromyscus mouse Conclusion: These studies confirm for the first time the existence of this emerging zoonosis in Latin America, and leaves open the intriguing possibility that this represent an example of the epidemiological transition due to world climate changes.

D. Miller University of Hawaii, Honolulu, HI, USA Background: Egypt has the highest prevalence of antibodies to Hepatitis C virus (HCV) in the world, estimated to be 14.7% by the first national study completed by the Egyptian Demographic Health Survey. Numerous seroprevalence studies dating back to 1993, published various estimates from different communities, mostly rural, had strongly suggested that, Egypt, relative to the other nations of the world, has a HCV epidemic. More importantly, the new national data base provided an opportunity to apply established epidemiologic models to estimate incidence, from the prevalence of anti-HCV antibodies. Methods: Validated mathematical models for estimating incidence from age specific prevalence were use. We reviewed all previous seroprevalence studies and estimated incidence from each study that provided sufficient age specific prevalence required by the models. Results: On review, it was not possible to establish a benchmark for HCV prevalence or incidence prior to the 2008 national study. The modeled incidence from the national study and collectively, from the modeled incidence from the previous seroprevalence studies were, 6/1000 per person per year and 6.57/1000 per person per year, respectively. Projected to the age structure of the Egyptian population, there are and estimated 535,093 new HCV infections per year. An estimated 4,458,691 persons are positive for HCV RNA and infectious. Conclusion: The study demonstrates the urgency to reduce HCV transmission in Egypt.
