Swat, a lush green valley of 1.3 million persons, remained under militant insurgency from 2007 to 2009, which damaged the health infrastructure. An outbreak of dengue fever (DF) was declared in the valley in 2013. To investigate this outbreak, we established active surveillance of national hospitals and private clinics, reviewed available clinical and laboratory records, and conducted entomological survey. From August to November 2013, 16,000 suspected patients with acute febrile illness were presented to health facilities...

In Pakistan which ranked second in terms of hepatitis C virus (HCV) infection, it is highly needed to have an established diagnostic test for antiviral therapy response prediction. Interleukin 28B (IL-28B) genetic testing is widely used throughout the world for interferon based therapy prediction for HCV patients and is quite helpful not only for health care workers but also for the patients. There is a strong relationship between single nucleotide polymorphisms at or near the IL-28B gene and the sustained virological response with pegylated interferon plus ribavirin treatment for chronic hepatitis C...

Dengue fever is regarded as one of the most prominent emerging arboviral infections in Pakistan since its first epidemic almost 2 decades ago. Interplay between potential vectors, susceptible host, and lax environmental conditions may promote the infection, leading to an epidemic. These factors may indeed have played a major role in the spread of the disease in the country, which was limited to Karachi till 2006. With recent natural disasters such as the earthquake in 2005 and flooding in 2010, 2011 and 2012, numbers of vector-borne diseases and outbreaks including dengue fever are on the rise in Pakistan...

Thousands of lives are lost every year in developing countries for failing to detect epidemics early because of the lack of real-time disease surveillance data. We present results from a large-scale deployment of a telephone triage service as a basis for dengue forecasting in Pakistan. Our system uses statistical analysis of dengue-related phone calls to accurately forecast suspected dengue cases 2 to 3 weeks ahead of time at a subcity level (correlation of up to 0.93). Our system has been operational at scale in Pakistan for the past 3 years and has received more than 300,000 phone calls...

BACKGROUND & OBJECTIVES: Dengue is one of the most common arthropod-borne viral diseases which is transmitted mainly by two vector species, Aedes aegypti (Linnaeus 1762) and Ae. albopictus (Skuse, 1894) worldwide. As there is no effective medicine and vaccine available, vector control remains the most effective measure to prevent its transmission and outbreak. The aim of the study was to confirm the co-occurrence of Aedes aegypti and Ae. albopictus populations in the different localities of Rawalpindi, Pakistan and examine their susceptibility status against different groups of insecticides...

Pakistan is a developing country that has a population of 190 million people and faces a huge burden of viral diseases. Every year during monsoon season heavy rain fall and lack of disaster management skills potentially increase the transmission of waterborne diseases, vector borne diseases and viral outbreaks. Due to severe flooding, thousands of people lose their lives and millions are displaced each year. In most of the cases the children who lose their family members are forced into illegal professions of begging, child labor and prostitution which make them prone to sexually transmitted infections...

Dengue fever is currently the most prevalent disease caused by mosquito-borne flaviviruses. Despite being potentially fatal, there are no specific antiviral therapies for Dengue virus (DENV) infections. Therefore, early, accurate, and rapid diagnosis plays an important role in proper patient management. In this study, we evaluated the performance of a probe-based real-time RT-PCR (rRT-PCR) assay against that of a conventional RT-PCR assay in three sample cohorts from Pakistan (n = 94) and Singapore (first cohort; n = 559, second cohort; n = 123)...

INTRODUCTION: Dengue is a significant arboviral infection that represents a major public health concern worldwide. The infection is endemic in most parts of South East Asia, sub-Saharan Africa, and Latin America. Among the four dengue virus (DENV) serotypes, DENV-2 has been reported to be the predominant serotype in Saudi Arabia since 1992. However, virological and epidemiological data of DENV-2 from Saudi Arabia are severely deficient and require further investigations. METHODS: Full genome sequencing of a recent DENV-2 isolate and phylogenetic analysis of all available DENV-2 sequences from Saudi Arabia...
