This depends on the amount of water damage and mold that grows after an incident. Research suggests that there will be an increase of 30-50% in adverse respiratory health outcomes caused by dampness and mold exposure for those living in coastal and wetland areas. Fungal contamination in homes is associated with increased allergic rhinitis and asthma. Vector borne diseases increase as well due to the increase in still water after the floods have settled. The diseases that are vector borne are  malaria, dengue, West Nile, and yellow fever. Floods have a huge impact on victims psychosocial integrity. People suffer from a wide variety of losses and stress. One of the most treated illness in long-term health problems are depression caused by the flood and all the tragedy that flows with one. Loss of life
Below is a list of the deadliest floods worldwide, showing events with death tolls at or above 100,000 individuals. Secondary and long-term effects
Economic hardship due to a temporary decline in tourism, rebuilding costs, or food shortages leading to price increases is a common after-effect of severe flooding. The impact on those affected may cause psychological damage to those affected, in particular where deaths, serious injuries and loss of property occur. Urban flooding also has significant economic implications for affected neighborhoods. In the United States, industry experts estimate that wet basements can lower property values by 10–25 percent and are cited among the top reasons for not purchasing a home.
Erythema marginatum is a type of erythema (redness of the skin or mucous membranes) involving pink rings on the torso and inner surfaces of the limbs which come and go for as long as several months. It is found primarily on extensor surfaces.An association with bradykinin has been proposed in the case of hereditary angioedema. Presentation
The rings are barely raised and are non-itchy. The face is generally spared. Associated conditions
It occurs in less than 5% of patients with rheumatic fever, but is considered a major Jones criterion when it does occur. The four other major criteria include carditis, polyarthritis, Sydenhams chorea, and subcutaneous nodules. In this case, it is often associated with Group A streptococcal infection, otherwise known as Streptococcus pyogenes infection, which can be detected with an ASO titer.It is an early feature of rheumatic fever and not pathognomonic of it. It may be associated with mild myocarditis (inflammation of heart muscle). It is also seen in conditions like allergic drug reactions, sepsis and glomerulonephritis.It often occurs as a harbinger of attacks in hereditary angioedema. In this case it may occur several hours or up to a day before an attack. Diagnosis
Types
Some sources distinguish between the following:
"Erythema marginatum rheumaticum"
"Erythema marginatum perstans"

Treatment
Erythema marginatum can be treated with hydrocortisone and adrenocorticotropc hormone (ACTH). References
