Roxanne Connelly Received: 30 October 2014; in revised form: 4 December 2014 / Accepted: 9 December 2014 / Published: 16 December 2014 Abstract: Florida (USA), particularly the southern portion of the State, is in a precarious situation concerning arboviral diseases. The geographic location, climate, lifestyle, and the volume of travel and commerce are all conducive to arbovirus transmission. During the last decades, imported dengue cases have been regularly recorded in Florida, and the recent re-emergence of dengue as a major public health concern in the Americas has been accompanied by a steady increase in the number of imported cases. In 2009, there were 28 cases of locally transmitted dengue in Key West, and in 2010, 65 cases were reported. Local transmission was also reported in Martin County in 2013 (29 cases), and isolated locally transmitted cases were also reported from other counties in the last five years. Dengue control and prevention in the future will require close cooperation between mosquito control and public health agencies, citizens, community and government agencies, and medical professionals to reduce populations of the vectors and to condition citizens and visitors to take personal protection measures that minimize bites by infected mosquitoes.

In the last 25 years of the 20th century the pandemic intensified, with increased geographic spread of both the viruses and the principal mosquito vec- fever and dengue tor, Aedes aegypti. This led to larger and more frequent epidemics and to the emergence of DHF as tropical countries and regions became hyperendemic with hemorrhagic fever the co-circulation of multiple virus serotypes. With the exception of sporadic epidemics in the Caribbean islands, in the Americas: dengue and yellow fever were effectively controlled in the Americas from 1946 a case of failed until the late 1970s as a result of the Ae. aegypti eradication program conducted by the Pan American Health Organization (PAHO) (1, 2). This was a vertically struc- public health policy tured, paramilitary program that focused on mosquito larval control using source reduction and use of insecticides, primarily dichlorodiphenyltrichloroethane (DDT). This highly successful program, however, was disbanded in the early 1970s because there was no longer a perceived need and there were competing 1 Duane Gubler priorities for resources; control of dengue and yellow fever was thereafter merged with malaria control. Another major policy change at that time was the use of ultra-low-volume space sprays for killing adult mosquitoes (adulticides) as the rec- ommended method to control Ae. aegypti and thus prevent and control DF and DHF. Both of these decisions were major policy failures because they were inef- fective in preventing the re-emergence of epidemic DF and the emergence of DHF in the Region.

  • Strengthening Integrated Surveillance for Arboviruses in the Mediterranean and Black Sea Regions in the Framework of the One Health Approach

We conducted a survey with 19 countries to assess and document the level of integration in surveillance of arboviruses between four disciplines: animal virology, human virology, medical entomology and human epidemiology across three different levels: policy and institutional, data collection and analysis, dissemination of results. Seventy-five contact points (CP) of the four disciplines from the 19 countries were invited to the survey. Responses were obtained from 63 CP (81%) of whom: 14 from the Black Sea, 26 from North Africa and the Middle East and 23 from the Balkans. Integration on all the explored levels was confirmed by all four disciplines indepen- dently in any of the countries included in the study. This suggests that implementation of fully integrated one health surveil- lance across the policy and institutional level to the data collection and dissemination level is yet to be fully developed in the Mediterranean and Black Sea regions with the four considered disciplines.

An external quality assessment of mosquito identification capacities was carried out within the MediLabSecure Network, which is composed of laboratories located in 19 countries close to the European Union around the Mediterranean and Black seas. Methods: A set of blind samples consisting of 7 or 8 adult mosquitoes and 4 larvae was given to each participant laboratory. In all, 138 adult mosquitoes and 76 larvae of different species were distributed for genus and species identification. Results: All identifications were exclusively morphology based. Overall, 81% of identifications were correct at the genus level, 64% at the species level. The results were highly varied among the 19 participating laboratories. The levels of correct identifications were: 100% (three laboratories), 90–95% (four laboratories), 50–75% (six laboratories) and < 50% (six laboratories). Conclusions: This evaluation showed the need to maintain efforts in capacity building and quality control in the field of medical entomology and, more specifically, in the morphological identification of the Culicidae.

  • BMBL) Quickly Became the Cornerstone of Biosafety Practice and Policy in the United States Upon First Publication in 1984
    Biosafety in Microbiological and Biomedical Laboratories 5th Edition U.S. Department of Health and Human Services Public Health Service Centers for Disease Control and Prevention National Institutes of Health HHS Publication No. (CDC) 21-1112 Revised December 2009 Foreword Biosafety in Microbiological and Biomedical Laboratories (BMBL) quickly became the cornerstone of biosafety practice and policy in the United States upon first publication in 1984. Historically, the information in this publication has been advisory is nature even though legislation and regulation, in some circumstances, have overtaken it and made compliance with the guidance provided mandatory. We wish to emphasize that the 5th edition of the BMBL remains an advisory document recommending best practices for the safe conduct of work in biomedical and clinical laboratories from a biosafety perspective, and is not intended as a regulatory document though we recognize that it will be used that way by some. This edition of the BMBL includes additional sections, expanded sections on the principles and practices of biosafety and risk assessment; and revised agent summary statements and appendices. We worked to harmonize the recommendations included in this edition with guidance issued and regulations promulgated by other federal agencies. Wherever possible, we clarified both the language and intent of the information provided. The events of September 11, 2001, and the anthrax attacks in October of that year re-shaped and changed, forever, the way we manage and conduct work

Thus the study on insects and how they affect the human and animal lives have gained importance in recent times. Insect Genomics involving the studies of the whole genome sequences are being developed and gene expression and regulation studies are elucidating their roles in regulating the vector competence. This finds importance in deducing strategies for vector control thereby preventing disease spread that is fatal to man and animal life. In this review we have studied the medical entomology (i) from historical perspective (ii) diverse role of arthropods in causing diseases (iii) common pathogens transmitted by arthropod vectors (iv) major arthropod borne diseases (v) pharmaceutically important insects.
