What does London, a waterpump and a guy called John Snow have to do with the scientific discipline of epidemiology?

Well, In the mid-1800s, a London physician John Snow made a startling discovery that would change the way that we view diseases and how they propagate. He created a map depicting where cases of cholera occurred in London's West End and found them to be clustered around a water pump on Broad Street. John snow decided to remove the handle of the waterpump and cholera came to an end in London just a few days later.

The scientific discipline if epidemiology was born.

What is epidemiology?

Epidemiology is the study of patterns in health related states and events - this can be more than just diseases. These are studied in specific areas to find certain patterns throughout that community.

Examples of epidemiology

Some examples of topics examined through epidemiology include high blood pressure, mental illness and obesity. These can be studied throughout a community to connect a pattern and possibly a solution.

Disease surveillance data is used to determine the need for public health action. During a public health emergency response, epidemiology is used to understand the needs of affected populations, the nature of the disease or exposure, and to inform control activities.

How does John Snow’s work relate to our Co2 monitors?

John snow aided in controlling and neutralising the spread of a virus. This is what the CO2 monitors are helping with too.

Every day these devices are aiding people to help neutralize the spread of this modern and dangerouse virus.

John Snow helped with the birth of the fresh water revolution - our CO2 monitors help do the same for fresh air.

CO2 ppm - what does it mean?

Water pump water pump ppm stands for parts per million. This number tells how many parts of carbon dioxide there are in one million parts of air. For example if the carbon dioxide is at 546 parts per million (or ppm), that means in one million particles of air there are 546 particles of carbon dioxide.OSHA (Occupational Safety and Health Administration) has established a Permissible Exposure Limit for CO2 of 5,000 ppm averaged over an 8-hour work day.Green is 450 -800Blue - CO2 below 800ppm Yellow - CO2 800 to 1000ppm Orange - CO2 1000 to 1500ppm (a double beep will alarm at 1000 and 1200ppm) Red - CO2 greater than 1500ppm (a continuing beep will alarmAny alarms have a high chance of getting covid.
