NF can result from different bacterial pathogens, including Vibrio and Vancomycin-Intermediate/Resistant Staphylococcus aureus (VISA/VRSA). During routine disease surveillance, complications that result from Vibrio infection may occur after patient interviews, and therefore may not be reported.

The protozoans, such as giardia and cryptosporidium, are much more resistant and may survive even high concentrations of chlorine. Major precipitation events such as heavy rains or snowfall increase the risk of the water-borne diseases. Several instances of the outbreak of epidemic infections after natural calamities such as flood have been recorded in history. Increased frequency of intense extreme weather events can cause flooding of water and sewage treatment facilities, increasing the risk of waterborne diseases. CDC’s first estimates of the impact of waterborne disease in the United States cover illnesses tied to all types of water use.

Apart well drilling from the precautions at an individual level, several other approaches including mass recycling of water and carbon sequestration are employed to control the water-borne diseases. Protecting the natural water sources and lands is another important strategy to combat climate change. Effective irrigation techniques have been developed by agricultural scientists for optimal usage of water during farming.

The bacterial spores that cause it are common in both soil and water. They produce botulinum toxin when exposed to low oxygen levels and certain temperatures. Infant botulism happens when the bacteria develops in the intestines and releases toxin. Typically this only happens in children less than six months of age as after that protective mechanisms develop.

Typhoid fever is caused by Salmonella typhi bacteria transmitted via contaminated water. The patients typically suffer from prolonged episodes of fever, loss of appetite, nausea, headache, constipation, and loss of body weight.
