How Many People Die Annually Due to Poor Hygiene? A Statistical Analysis

Annually more than 1.4 million lives are lost due to the illnesses related to the usage of contaminated drinking water and inadequate levels of personal hygiene and sanitation facilities.

According to the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), mortality rates among the underdeveloped and developing nations in connection with poor hygiene continue to account for an extremely high proportion of all fatalities related to this issue.

When analyzing sanitation and hygiene statistics, one cannot ignore the shocking figures that emerge. Not only do such deaths create health problems for individuals, but they have also become a silent threat to entire nations.

This article will present the statistics related to the issue of hygiene and sanitation deaths. Moreover, it will discuss which diseases have the highest rates of such mortalities and analyze possible methods to prevent further deaths.

How Many People Die From Poor Hygiene Each Year Worldwide?

To estimate the mortality associated with hygiene on a global scale, one needs to analyze several datasets with overlapping data. The most commonly used figures refer to the WHO report, which estimates that about 1.4 million lives are lost annually due to insufficient access to drinking water, sanitation, and hygiene combined. 

In 2019, according to the Global Burden of Disease Study, unsafe WaSH (Water, sanitation and hygiene) resulted in approximately 1.65 million annual deaths, reflecting a decline of 49% from 1990. Nevertheless, even despite the efforts made to tackle the problem globally, millions of individuals still lose their lives to the problem, although it can be prevented relatively easily. 

Specifically, deaths caused by poor sanitation take up to 564,000 lives per year due to diarrhea diseases. In addition to that, 502,000 lives are lost due to unsafe water intake and 297,000 lives are claimed by poor hand hygiene every year.

Key Statistics at a Glance:

• 1.4 million deaths per year are attributed to unsafe water, poor sanitation, and lack of hygiene.

• 829,000 people die annually from diarrhea linked to inadequate water, sanitation and hygiene.

• More than 500,000 people die each year due to lack of handwashing facilities.

• 2.3 billion people worldwide lack access to a basic handwashing facility with soap and water.

• 3.6 billion people, nearly half the global population lacks safe sanitation at home

Deaths Due to Lack of Clean Water and Waterborne Diseases

The shortage of clean water is among the most important causes of deaths resulting from poor sanitation and hygiene across the globe. The global death rate for waterborne illnesses continues to be worryingly high, with diarrhea, cholera, typhoid, and dysentery being some of the top killers.

As noted by WHO, 829,000 people lose their lives annually from diarrheal illnesses brought about by water contamination and poor sanitation. This is because waterborne illnesses are usually found in regions where there is no clean water, proper sewage handling facilities, or handwashing habits. 

Also, it needs to be pointed out that 44% of domestic wastewater produced globally remains untreated and gets dumped into the environment in 2020 alone, according to WHO statistics. It is assumed that at least 10% of the population consumes fruits and vegetables irrigated with wastewater.

The Path Forward

There is hope in these hygiene-related deaths figures as the solutions to address them are known, affordable, and efficient. Poor hygiene statistics show how hygiene results in deaths statistics and provide a clear point for intervention, and the evidence is strong. According to a review published in 2018 and cited by the CDC, educating communities on handwashing with soap and water led to a 30% reduction in diarrhea. If implemented globally, this would result in 1 million fewer deaths each year.

Interventions to improve sanitation facilities, increase access to clean water infrastructure, and introduce hygiene education programs have shown a reduction in mortality rates in several regions. Water, sanitation, and hygiene interventions including water supply, sanitation, and hygiene can lead to a 25 to 35% reduction in diarrheal diseases according to WHO European Region.

The Global Burden of Disease Study 2019 revealed that providing universal access to improved water, sanitation, and hygiene could save around 1.4 million lives and about 74 million disability-adjusted life years (DALYs). However, improvements vary worldwide as despite a 49% decrease in WaSh-related deaths since 1990, billions of people lack basic sanitation services.

The Sustainable Development Goal (SDG) Target 6.2 calls for universal access to safe and equitable sanitation and hygiene by 2030. Meeting this target demands coordinated investment in infrastructure, community education, policy reform, and the availability of quality sanitation products at scale.

Conclusion

It’s quite obvious; poor sanitation and hygiene lead to deaths in millions every year, more often than not involving the most vulnerable members of society, which include young children, women, and people residing in low-income areas where neither proper sanitation nor clean water and toilets are available.

Being aware of such a problem is the first step towards its resolution, but being aware alone will not solve anything. This is precisely why the contribution made by VkareTheory can be significant. Vkare Theory is a company that provides various hygiene products that will help overcome the lack of awareness of such problems.
