This report is prepared by the Division of Disease Control and is intended to provide an overview of notifiable infectious diseases of public health importance in Maine. We could not produce this report without the continued support of our healthcare and public health partners throughout the state. We greatly appreciate all of the laboratories, healthcare providers, childcare centers, school nurses, veterinarians, and others who provide disease surveillance information. Considerable time is spent assisting Maine CDC with infectious disease investigations and disease control measures that affect Maine residents. Public health partners’ active and critical role in the infectious disease surveillance cycle informs statewide policies and programs that protect our residents from infectious diseases through health promotion, disease prevention, early detection, containment, and treatment. We appreciate and encourage your vigilance in the effort to protect the people of Maine through timely, complete, and accurate notifiable infectious disease reporting. It is through these collaborative efforts that we are able to respond to emerging infectious disease threats and prevent outbreaks. We hope you find this report useful as we all work to protect and promote the health of Maine’s residents. As always, we welcome your feedback on how we can provide more useful disease information to you, our partners. For more information on what, when, and how to report infectious diseases please see Appendix J (Notifiable Conditions List) of this report, visit our website at www.mainepublichealth.gov, or call 1-800- 821-5821.

  • Joint Statement on Insect Repellents by EPA And
    Joint Statement on Insect Repellents from the Environmental Protection Agency and the Centers for Disease Control and Prevention July 17, 2014 The Environmental Protection Agency (EPA) and Centers for Disease Control and Prevention (CDC) are recommending that the public use insect repellents and take other precautions to avoid biting insects that carry serious diseases. The incidence of these diseases is on the rise. This joint statement discusses diseases that are transmitted by ticks and mosquitoes, the role of government in vector control and disease prevention, the history of repellents, how to use repellents as part of an integrated control program, and how to select and use a repellent. Introduction and Purpose CDC and EPA developed this joint statement to promote awareness of repellents and to highlight the effectiveness of repellents in preventing mosquito and tick bites. The agencies believe that promoting the use of repellents may reduce the impact of diseases and nuisance effects caused by these pests. Vector-borne diseases, such as those transmitted by mosquitoes and ticks, are among the world's leading causes of illness and death today. A wide variety of arthropods, including mosquitoes, ticks, fleas, black flies, sand flies, horse flies, stable flies, kissing bugs, lice and mites, feed on human blood. Among these, mosquitoes and ticks transmit some of the most serious vector- borne diseases both globally and within the United States. Diseases Transmitted by Mosquitoes and Ticks Mosquito-transmitted West Nile virus caused over 36,000 disease cases and 1,500 deaths in the United States between 1999 and 2012 (CDC, 2012). Mosquitoes also transmit other viruses that cause severe disease in the United States, including La Crosse encephalitis, eastern equine encephalitis and dengue.

  • A New Tick-Borne Encephalitis-Like Virus Infecting New England Deer Ticks, Ixodes Dammini1
    Dispatches A New Tick-borne Encephalitis-like Virus Infecting New England Deer Ticks, Ixodes dammini1 To determine if eastern North American Ixodes dammini, like related ticks in Eurasia, maintain tick-borne encephalitis group viruses, we analyzed ticks collected from sites where the agent of Lyme disease is zoonotic. Two viral isolates were obtained by inoculating mice with homogenates from tick salivary glands. The virus, which was described by reverse transcriptase polymerase chain reaction and direct sequencing of the amplification products, was similar to, but distinct from, Powassan virus and is provisionally named “deer tick virus.” Enzootic tick-borne encephalitis group viruses accompany the agents of Lyme disease, babesiosis, and granulocytic ehrlichiosis in a Holarctic assemblage of emergent deer tick pathogens. American zoonotic foci of the agents of Lyme humidified chamber until dissection, no more disease (Borrelia burgdorferi, a spirochete) and than 1 month after they were removed from hosts. human babesiosis (Babesia microti, a protozoon) Each field-derived tick was dissected into a were first recognized in coastal New England and drop of sterile Hanks Balanced Salt Solution with the northern Great Plains during the 1960s and 15% fetal bovine serum (HBSS/FBS), and one of 1970s (1).

    7/13/2011 Transmission of Diseases via Animals and Insects Greta Schuster, PhD. Associate Professor, IPM Texas A&M University ‐ Kingsville Environmental and Children’s Health Training Texas AgriLife Research & Extension Center Weslaco, TX June 23, 2011 Zoonotic infections • Zoonoses are infections that can be passed from animals to humans. • Sources of zoonoses include cattle, sheep, horses, pigs, dogs, cats, chickens, native birds, kangaroos, wild animals, rodents, reptiles (including turtles and tortoises) and bats. 1 7/13/2011 • A zoonotic disease is a disease that can be shared between animals and people. • A person may become infected with an animal disease indirectly (from the environment or through flies, mosquitoes, ticks, and fleas) or directly (through close contact between animals and people). Ways Zoonotic Diseases Are Spread • Fecal‐oral route ‐Animal feces may pass directly from soiled hands to mouth, or indirectly by way of objects, surfaces, water or food contaminated with feces. • Inhalation ‐ Humans may breathe in droplets containing harmful organisms (aerosols) originating from an infected animal. 2 7/13/2011 Ways Zoonotic Diseases Are Spread • Ingestion ‐ Consuming contaminated food or water may lead to illness –for example, consumption of unpasteurized milk from an infected animal or eating animal feed. • Vector transmission Vector • Biological Vector –e.g. mosquitoes that transmit WNV • Mechanical Vector –insect that carries pathogen on body surface or mouthparts, or even within the gut but which does not allow for multiplication of the pathogen. House flies – Think dirty needle! 3 7/13/2011 Vector‐borne Diseases • A vector‐borne disease is one in which the pathogenic microorganism is transmitted from an infected individual to another individual by an arthropod or other agent, sometimes with other animals serving as intermediary hosts.

  • Arboviral Infection Surveillance Protocol
    March 2017 Arboviral Infection Surveillance Protocol Arboviruses endemic to the U.S. include Eastern equine encephalitis virus (EEE), La Crosse encephalitis virus (LAC), Saint Louis encephalitis virus (SLE), West Nile virus (WNV), Western equine encephalitis virus (WEE), and Powassan encephalitis virus (POW), a tickborne arboviral disease that has not been reported in humans in West Virginia. Chikungunya is an arbovirus that is associated with travel to an endemic country. These arboviral diseases (and those included in the most recent CDC case definition) are reportable to the local health department where the patient resides within one week. Dengue, yellow fever, and Zika virus disease have earlier notification timelines and, therefore, have their own disease surveillance protocols. Provider Responsibilities For reporting of endemic arboviral diseases (WNV, LAC, SLE, EEE): 1. Report suspect and confirmed cases of arbovirus infection (including copies of lab results) to the local health department within one week of diagnosis. Supply requested clinical information to the local health department to assist with case ascertainment. 2. Assure appropriate testing is completed for patients with suspected arboviral disease infection. The preferred diagnostic test is testing for virus-specific IgM antibodies in serum or cerebrospinal fluid (CSF). In West Virginia, appropriate endemic arbovirus testing should include EEE, LAC, SLE, and WNV. Testing for LAC, SLE, and WNV is available at no cost to the patient through the West Virginia Office of Laboratory Services (OLS). Confirmatory testing may be conducted at the Centers for Disease Control and Prevention (CDC). For reporting of non-endemic arboviral diseases (e.g. chikungunya): 1. Report suspect and confirmed cases of arbovirus infection (including copies of lab results) to the local health department within one week of diagnosis.
