Mosquito Awareness Week Mosquito Awareness Week. This measure would declare that the week of April 19, 2026, to April 25, 2026, inclusive, be designated as Mosquito Awareness Week. NO

WHEREAS, The United States Environmental Protection Agency recognizes that mosquitoborne diseases are currently among the world’s leading causes of illness and death; and

WHEREAS, The World Health Organization estimates that more than 300,000,000 clinical cases each year are attributable to mosquito-borne illnesses; and

WHEREAS, Excess numbers of mosquitoes and other vectors spread diseases, reduce the enjoyment of both public and private outdoor living spaces, reduce property values, hinder outdoor work, reduce livestock productivity, and have a negative impact on the environment; and

WHEREAS, Climate change is driving extreme weather events, including heavy rains, flooding, hurricanes, and wildfire burn scars, that expand mosquito breeding habitats, prolongs mosquito seasons, accelerates the spread of the invasive and costly to control Aedes species, and forces mosquito control agencies into reactive public health responses; and

WHEREAS, Two invasive mosquito species in California, Aedes albopictus, the Asian tiger mosquito, which was detected in southern California in 2011, and Aedes aegypti, the yellow fever mosquito, which was detected in central and northern California in and southern California in and currently found in counties statewide, are posing new public health threats due to their capability to transmit potentially deadly or debilitating diseases, such as dengue fever, yellow fever, chikungunya, and Zika virus, which can cause significant birth defects; and

WHEREAS, Since 2015, there have been travel-associated cases of Zika virus detected in California, including infections in pregnant women and infants born with complications; and

WHEREAS, Since 2016, there have been 2,033 travel-associated cases of dengue fever in counties, and the presence of the mosquito vector in California has resulted in locally acquired human cases of dengue fever since 2023; and

WHEREAS, In addition to new, emerging diseases, California must remain vigilant in fighting known diseases. West Nile virus is a mosquito-borne disease that can result in debilitating cases of meningitis and encephalitis, and death to humans, horses, avian species, and other wildlife; and

WHEREAS, In 2025, West Nile virus resulted in human deaths in California and individual cases in counties; and

WHEREAS, In 2025, there were human cases of St. Louis encephalitis virus; and

WHEREAS, In 2025, 6 locally acquired human cases of dengue fever were detected in southern California, making it the third year of documented local transmission; and

WHEREAS, A study from the University of California, Los Angeles found that low socioeconomic status was an indicator of the likelihood of West Nile virus cases; and

WHEREAS, Adequately funded mosquito and vector control, disease surveillance, and public awareness programs, coupled with best management practices on public and private lands, are the best ways to prevent outbreaks of West Nile virus and other diseases borne by mosquitoes and other vectors; and

WHEREAS, As a result of the threat mosquitoes posed to California’s economic development and health of its citizens, the Legislature enacted California’s Mosquito Abatement Districts Act (Assembly Bill of the Regular Session) 111 years ago; and

WHEREAS, Professional mosquito and vector control, based on scientific research, has made great advances in safely reducing mosquito and vector populations and the diseases they transmit; and

WHEREAS, Established mosquito-borne and vector-borne diseases such as plague, Lyme disease, flea-borne typhus, and encephalitis, and new and emerging vector-borne diseases, such as hantavirus, arenavirus, babesiosis, and ehrlichiosis, cause illness and sometimes death every year in California; and

WHEREAS, In 2019, the Legislature established the California Mosquito Surveillance and Research Program to support advanced data collection and analysis tools, such as the California Vectorborne Disease Surveillance Gateway (CalSurv), and to foster collaborative research in vector control; and

WHEREAS, Mosquito and vector control districts throughout California work closely with the United States Environmental Protection Agency and the State Department of Public Health to reduce pesticide risks to humans, animals, and the environment while protecting human health from mosquito-borne and vector-borne diseases and nuisances; and

WHEREAS, Best management practices, emphasizing nonchemical approaches, have been developed to guide mosquito control that can significantly reduce mosquito populations for new developments and on state and private lands; and

WHEREAS, The State Department of Public Health maintains information on how to eliminate risks from vectors at both www.cdph.ca.gov and westnile.ca.gov, which the public is encouraged to review; and

WHEREAS, The public’s awareness of the health benefits associated with safe, professionally applied mosquito and vector control methods will support these efforts, as well as motivate the state and the public to eliminate mosquito and vector breeding sites on public and private property; and

WHEREAS, Educational programs have been developed to include schools, civic groups, private industry, and governmental agencies in order to meet the public’s need for information about West Nile virus, other diseases, and mosquito and vector biology and control; and

WHEREAS, Public awareness can result in reduced production of mosquitoes and other vectors on residential, commercial, and public lands by responsible parties, avoidance of the bites of mosquitoes and other vectors when the risk of West Nile virus and other disease transmission is high, detection of human cases of mosquito-borne and vector-borne diseases that otherwise may be misdiagnosed for lack of appropriate laboratory testing, and the formation of mosquito or vector control agencies where needed; and

WHEREAS, Public awareness can result in action to provide adequate funding for existing mosquito and vector control agencies or to create control agencies in areas where there are no existing controls; and

WHEREAS, Mosquito Awareness Week will increase the public’s awareness of the threat of dengue fever, West Nile virus, and other diseases, and the activities of the various mosquito vector surveillance and control agencies working to minimize the health threat within California, and will highlight the educational programs currently available; and

WHEREAS, The Mosquito and Vector Control Association of California has designated the week of April 19, 2026, to April 25, 2026, inclusive, as West Nile Virus and Mosquito and Vector Control Awareness Week in California;

now, therefore,

be it Resolved by the Assembly of the State of California, the Senate thereof concurring, That the Legislature hereby declares that the week of April 19, 2026, to April 25, 2026, inclusive, be designated as Mosquito Awareness Week; and be it further Resolved, That the Chief Clerk of the Assembly transmit a copy of this resolution to the Governor, the State Public Health Officer, and the author for appropriate distribution.
