Human dengue virus infection without mosquito vector has been reported to occur as a result of mucocutaneous transmission, needlestick in patient care and laboratory accident, blood transfusion, bone marrow transplant, organ transplant, intrapartum and perinatal transmission, and breastfeeding. The emergence of Zika virus, another mosquito-borne flavivirus, has illustrated additional potential ...

Deterministic and stochastic models motivated by Salmonella transmission in unmanaged/managed populations are studied. The SIRS models incorporate three routes of transmission (direct, vertical and indirect via free-living infectious units in the environment). With deterministic models we are able to understand the effects of different routes of transmission and other epidemiological factors on...

Power transmission lines routes mapping is an important technique for locating power transmission line routes and towers on mountain/hilltops to assist viewing of their impacts on the environment, operations and allocation of public utilities. A study was therefore conducted to map the power transmission lines within Bukit Lanjan PLUS highway. The main objective of this study is to assess the c...

A long-standing debate questions whether the World Trade Organization’s (“WTO”) formal dispute settlement procedures level the playing field for lower income countries in international trade disputes, or instead, merely give opportunistic and sophisticated countries complex * Trade Counsel, Committee on Ways and Means, U.S. House of Representatives; J.D., Harvard Law School, 2007; M.P.P., Georg...

BACKGROUND AND AIMS Acute hepatitis C virus infection in the era of universal screening of blood products has not disappeared, and is thought to be transmitted primarily via injecting drug use. A growing body of evidence supports iatrogenic transmission as an important mode of transmission. The aim of this study was to examine transmission routes and clinical characteristics in a group of patie...

Whole-genome sequencing of pathogens has recently been used to investigate disease outbreaks and is likely to play a growing role in real-time epidemiological studies. Methods to analyze high-resolution genomic data in this context are still lacking, and inferring transmission dynamics from such data typically requires many assumptions. While recent studies have proposed methods to infer who in...

BACKGROUND Young people are of particular importance in state policies against Acquired Immunodeficiency Syndrome (AIDS). We intended to assess the knowledge and attitude of high school students regarding AIDS in Iran. METHODS Through a cluster-sampling, 4641 students from 52 high schools in Tehran were assessed by anonymous questionnaires in February 2002. RESULTS The students identified t...
