For more than 20 years, researchers have been investigating the implications of the observed and projected changes
in weather and climate for the magnitude and pattern of adverse climate-sensitive health outcomes. Mild winters, early
springs, and warmer temperatures are giving mosquitoes and ticks more time to reproduce, spread diseases, and
expand their habitats throughout the United States such as Lyme disease, West Nile virus disease, and Valley fever.
These are just some of the infectious diseases that are on the rise and spreading to new areas of the United States
between 2004 and 2018, the number of reported illnesses from mosquito, tick, and flea bites more than doubled, with
more than 760,000 cases reported in the United States. Nine new germs spread by mosquitoes and ticks were
discovered or introduced into the United States during this period. This paper has three aims. First, it conceptualizes
the potential direct and indirect health effects of climate change and provides an overview of factors that exacerbate
the health effects of climate change. Second, it summarizes the literature on the relationship between infectious
disease and climate change. Finally, it examines the impact of climate change on the spreading of the West Nile virus
outbreak in the US in 1999. Two major findings emerge from this paper. Climate change is shown to cause and
exacerbate multiple diseases, and the most adverse health impact on the spreading of more infectious diseases. hot
summer set the stage for an outbreak of West Nile virus disease in the United States, resulting in illnesses and deaths
among the population throughout the United States. Keywords: health impacts; infectious diseases, West Nile virus
