Extremely high biting densities of Aedes albopictus (Skuse) (Diptera: Culicidae) at a university campus in Nagasaki, Japan.

This study describes extremely high biting densities of A. albopictus at a campus of Nagasaki University, southwestern Japan. In August of 2015 and 2016, human-bait-sweep collection for 8 min obtained on average 33.4 and 38.9 females, respectively. In both 2015 and 2016, the highest and the second highest biting densities were observed in sites densely shaded by trees and covered with a lot of understory plants. In addition, major breeding sites were identified near these sites in 2016. A predaceous larval mosquito, Lutzia vorax Edwards, appeared to strongly suppress the breeding of A. albopictus in catch basins near the site with highest adult density, although its effect was insufficient to keep A. albopictus density at a low level. After cleaning the catch basins, A. albopictus immatures become more abundant especially in shallow catch basins in shaded sites. PMID: 31257243 [PubMed - as supplied by publisher]

In conclusion, the author of this paper mentioned that immunization gap needs to be handle systematically. Immunization data released on 2017 showed that complete immunization was given only to 20% of targeted group, while almost 75% were either unvaccinated or unknown. During the outbreak of diphteria in Indonesia, the WHO also reported several countries with similar problem such as Bangladesh, Haiti and Yamen. It was shown that a coordination between doctors in clinic/hospital with public health officer to conduct an epidemiological investigation, in conjunction with giving prophylaxis and assuring the logistics of anti-...

We reported serological and molecular detection of SLEV in a healthy population of equids and humans from rural areas in Southeast Brazil. A plaque reduction neutralization test was applied, and neutralizing antibodies were detected in 11 individuals (4.6%) and 60 horses (21.5%). A qPCR targeting the 5′UTR region and reverse transcription-PCR (RT-PCR) targeting the non-structural protein (NS5) gene were performed and three individuals tested positive in both assays. Subsequent phylogenetic analysis confirmed SLEV circulation and its findings suggest the occurrence of an asymptomatic or subclinical presence in hum...

While efforts to control malaria with available tools have stagnated, and arbovirus outbreaks persist around the globe, the advent of clustered regularly interspaced short palindromic repeat (CRISPR)-based gene editing has provided exciting new opportunities for genetics-based strategies to control these diseases. In one such strategy, called “population replacement”, mosquitoes, and other disease vectors are engineered with effector genes that render them unable to transmit pathogens. These effector genes can be linked to “gene drive” systems that can bias inheritance in their favor, providing nove...

Lassa fever outbreaks West Africa have caused up to 10,000 deaths annually. Primary infection occurs from contact with Lassa virus-infected rodents and exposure to their excreta, blood, or meat. Incubation takes 2 to 21  days. Symptoms are difficult to distinguish from malaria, typhoid, dengue, yellow fever, and other viral hemorrhagic fevers. Clinical manifestations range from asymptomatic, to mild, to severe fulminant disease. Ribavirin can improve outcomes. Overall mortality is between 1% and 15%. Lassa fever s hould be considered in the differential diagnosis with travel to West Africa. There is an urgent need for...

Abstract Flaviviruses comprise several medically important viruses, including Japanese encephalitis virus, West Nile virus, dengue virus (DENV), yellow fever virus and Zika virus (ZIKV). A large outbreak of DENV and ZIKV occurred recently, leading to many cases of illness and death. However, despite decades of efforts, we have no clinically specific therapeutic drugs against DENV and ZIKV. Previous studies showed that inflammatory responses play a critical role in dengue and Zika pathogenesis. Thus, in this study, we examined a series of novel anti-inflammatory compounds and found that treatment with compound 2d c...
