Legionnaires’ Disease in New York, Poverty Increases Risk

legionnaires-disease-new-yorkA new CDC study reveals that New Yorkers living in poverty are at a higher risk from the potentially fatal bug Legionnaires’ disease.

The US based Centers for Disease Control and Prevention (CDC) have recently published the findings of a comprehensive nine year study in to the incidence and risk factors associated with Legionnaires' disease in New York entitled “Legionnaires’ Disease Incidence and Risk Factors, New York, USA”.

This valuable study gives a range of insights into the various risk factors for ‘community acquired’ Legionnaires’ disease affecting New Yorkers.

The report notes that the incidence of Legionnaires’ disease in the United States is increasing and that overall, cases of the disease in the city of New York increased 230% from 2002 to 2009.

In this article our legionella experts look at one of the more notable factors highlighted in the CDC report, the correlation between poverty and community acquired Legionnaires’ disease.

‘Community acquired’ Legionnaires’ disease is classed as instances of Legionnaires’ that have not been acquired in a hospital, healthcare or care home environment.

The CDC study found a strong link between poverty and Legionnaires’ disease, with those New Yorkers living in the highest poverty areas being 2.5 times more likely to contract Legionnaires’ than those in the lowest poverty areas.

Legionnaires' Risk Factors

The strong link between poverty and Legionnaires’ disease could be attributed to a number of factors including:

Environment and Housing

Housing in areas with a high degree of poverty can often be of a poor quality and condition.

With low owner occupier rates, there can often be a problem with the transient nature of parts of the community, leading to very little investment being made into properties and their upkeep, which can obviously be a risk factor for the contamination and proliferation of legionella bacteria.

Underlying Health Issues

Residents of New York who live in the most deprived areas are statistically likely to die a decade earlier than those people in more affluent areas.

Additionally, their shorter life span will also see them enjoying 15% less time in what is classed as ‘good health’.

As we have seen from our previous article covering the increased incidence of Legionnaires’ disease in the over 50s, underlying medical conditions are a significant risk factor, with the vast majority of those people infected by the bug having at least one underlying health condition such as heart disease or diabetes.

Other Factors to Consider

The CDC report indicates a particular disparity in ethnic origin and risk of contracting Legionnaires’ disease, with non-Hispanic black people being most at risk of contracting Legionnaires’ disease.

The report does not conclude why this could be, but suggests socioeconomic factors could be contributory, as could a higher predisposition to certain health conditions such as diabetes.

Unlike the UK, where the National Health Service (NHS) offers free at the point of delivery health care, this is not the case in the USA where traditionally there is a private sector funded insurance backed healthcare system.

With the US Census Bureau’s report (Health Insurance Coverage in the United States) indicating that nearly 15 million people in the USA are without medical insurance, it is reasonable to presume that this is a contributory factor to the increased risks of suffering from Legionnaires’ disease in areas of deprivation.
