When rainfall is heavier than usual, health risks increase. Not only as a result of direct damage such as flooding, accidents, drownings, etc., but also because this precipitation can be an ideal place for certain diseases to spread.This is what happens with some infections gastrointestinal tract and respiratory systemspread of disease vector (Mosquitoes or ticks can cause malaria, dengue fever, Zika virus, etc.), fur and disease water transportthat is, through water (cholera, typhoid, hepatitis A).

What is the relationship between Heavy rain and respiratory and gastrointestinal infections?as this explains Scientific articles in 2019When flooding occurs, accumulated rainwater comes into contact with wastewater, causing wastewater contamination and making it a vector for a large number of pathogens, e.g.

norovirus, enterovirus, or bacteria Campylobacter. Many of these can cause stomach and respiratory infections.

The population will be Exposure to these pathogens is almost inevitable In case of flooding: due to cleaning tasks, splash water from vehicles and other pedestrians or direct contact with flood water (bathing or drinking in flood water, although the latter is Extremely rare in industrialized countries).Health studies conducted after the rainy season, e.g. Eastern Spain 2018 or in Netherlands 2019confirming that reports of gastrointestinal and respiratory disease cases increased after heavy rainfall.

About disease media communicationexist Record and literature Scientific evidence links outbreaks of these health problems to periods of heavy rainfall. Why does it happen?because Still water After a flood, flooding and rain mean Ideal environment for mosquitoes and ticks to lay eggs.Added to this is Mosquito Control Program When heavy rain or other extreme weather events occur, other vectors do not function as well and people may be less protected from mosquito bites (

Sleeping away from home due to flooding) and other human factors.

Some vector-borne diseases that increase after heavy rains are malariahe denguethis west nile virus fever, Rift Valley feverhe Chikungunya and Zika virus.

As for skin diseases, these can be caused by direct contact with contaminated water, which can lead to Wound infections, dermatitis and conjunctivitisalthough none of these have popular potential, According to WHO.In addition, damage to buildings caused by heavy rain may favor growth of Mold, known allergens promote skin diseases and respiratory system.

Finally, some pathogens spread better and are able to survive flooding and heavy rainfall that can come into contact with animal feces, which can contain microorganisms that can be transmitted to humans.They cause known diseases water transport (anger, Hepatitis A, cryptosporidiosis, Campylobacteriosis, Infect E. coli, salmonellosis and leptospirosis…) If drinking or coming into contact with contaminated water (mixed with feces or wastewater).

Not all of these diseases occur where it rains: Every region on earth has Epidemiology and health status different.
