Dengue fever (DF) is a mosquito-borne acute viral disease presenting with hemorrhagic manifestations in severe cases. Southeast Iran is in close proximity to Pakistan, an endemic country for DF. This cross-sectional study was conducted in the Sistan and Baluchestan province in the southeast of Iran to investigate possibility of DF (immunoglobulin M [IgM], immunoglobulin G [IgG], and nonstructural protein 1 [NS1] antigen tests) in 60 clinically suspected patients (April 2013 to August 2015). NS1 protein was detected in 5% ( N = 3), at least one of the antibodies (IgM and/ or IgG) was detected in 11% ( N = 7) of the samples...

Like most of the world, Pakistan has seen an increase in mosquito-transmitted diseases in recent years. The magnitude and distribution of these diseases are poorly understood as Pakistan does not have a nation-wide system for reporting disease. A cross-sectional study to determine which flaviviruses were causing of arboviral disease in Pakistan was instituted. West Nile virus (WNV) is a cause of seasonal fever with neurotropic findings in countries that share borders with Pakistan. Here, we describe the active and persistent circulation of WNV in humans in the southern region of Pakistan...

Aedes aegypti (L.) and Aedes albopictus (Skuse) are known vectors of dengue, chikungunya, and other pathogens; however, their ecology and role in virus transmission has not been well studied in Pakistan. Here, we report on an intensive survey of potential breeding sites of Ae. aegypti in Rawalpindi, Punjab Province, Pakistan. The study continued for 11 mo and was divided into three seasons: January to June (pre-monsoon), July to September (monsoon), and October-November (post-monsoon). Larval mosquitoes were collected from all wet containers present in and around the houses...

The gram-negative, pleomorphic endosymbiont Wolbachia is known to infect a large number of insects and other arthropods naturally. This bacterium modifies the host biology, mainly causing reproductive alterations including feminization, death of male, parthenogenesis, and importantly cytoplasmic incompatibility. Wolbachia-induced cytoplasmic incompatibility results in nonviable offspring and vector population suppression. In addition, this bacterium rapidly spreads and propagates within the host population...

BACKGROUND: The population of mosquitoes is mainly influenced by the biotic and abiotic factors. Although Aedes aegypti was reported until 1960's in the Punjab, Pakistan, the population has increased dramatically since 2009 and caused severe epidemics in 2011 due to heavy floods and rains. Thus, this study was carried out to know the effect of biotic and abiotic factors on the population of Aedes aegypti. METHODS: Mosquitoes were collected from fresh, sewage, and rain water ponds, fish ponds, rice fields, tyres, tree holes, and manmade storage containers present in and around residential homes twice during every winter (October-February), summer (March-June) and monsoon season (July-September) from marked rural areas...

Acute necrotizing encephalopathy of childhood (ANEC) is a rare condition mainly affecting children with a distinct clinico-radiologic pattern. Initially thought to be secondary to respiratory viral infections, there have been more insights to the pathogenesis of ANEC including genetics. We present a case of a girl who developed this condition with classical clinico-radiologic findings of ANEC secondary to severe dengue infection and could not survive. We report this case with the aim to raise awareness about this fatal complication of dengue infection as dengue has become a global health-care problem...

This work presents the evaluation of Raman spectroscopy using random forest (RF) for the analysis of dengue fever in the infected human sera. A total of 100 dengue suspected blood samples, collected from Holy Family Hospital, Rawalpindi, Pakistan, have been used in this study. Out of these samples, 45 were dengue-positive based on immunoglobulin M (IgM) capture enzyme-linked immunosorbent assay (ELISA) tests. For highlighting the spectral differences between normal and infected samples, an effective machine learning system is developed that automatically learns the pattern of the shift in spectrum for the dengue compared to normal cases and thus is able to predict the unknown class based on the known example...
