Some kinds of blue-green algae (cyanobacteria) create neurotoxins, hepatoxins, cytotoxins or endotoxins that can cause serious and sometimes fatal neurological, liver and digestive diseases in humans. Cyanobacteria grow best in warmer temperatures (especially above 25 degrees Celsius), and so areas of the world that are experiencing general ...
Climate change is altering the geographic range and seasonality of some insects that can carry diseases, for example Aedes aegypti, the mosquito that is the vector for dengue transmission. Global climate change has increased the occurrence of some infectious diseases. Infectious diseases whose transmission is impacted by climate change include, for example, vector-borne diseases like dengue ...
Pathogenic bacteria are bacteria that can cause disease. [1] This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and many are beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. [2]
The larvae and nymphs are active in spring and early summer, while adults may be active at both times. Deer ticks can transmit Lyme disease and babesiosis to humans. Lone star tick
Viruses are a major cause of human waterborne and water-related diseases. Waterborne diseases are caused by water that is contaminated by human and animal urine and feces that contain pathogenic microorganisms. A subject can get infected through contact with or consumption of the contaminated water.
The risk of acquiring Lyme disease from a tick bite is 1-3% in prevalent areas and is more common during late spring and summer months, peaking in June and July. Prompt tick removal reduces this risk.
The high case fatality rate of the disease only intensified people's fears despite the lack of evidence for human-to-human transmission. [16] Local restaurants saw a significant decline in business, many people stopped going to the movies, and very few people attended the annual Gallup Inter-Tribal Ceremonial that was held that summer.

The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
