What\u2019s an epidemiologist? \u2013 Vincent G, age 12, Arlington, Virginia<\/strong><\/p><\/blockquote>\n

\n

I\u2019m<\/a> an epidemiologist<\/a>.<\/p>\n

Unlike doctors and veterinarians<\/a>, who typically focus on treating one patient at a time, epidemiologists focus on big groups of people or animals. We try to prevent the spread of diseases.<\/p>\n

That means I study and teach students how to keep communities of people and clusters of animals<\/a> healthy.<\/p>\n

Epidemiologists need to know a lot about health and diseases. They also need to like math and working with numbers. Not all of us are doctors or vets.<\/p>\n

Like dominoes<\/h2>\n

Have you ever seen a big maze of dominoes? When one domino gets knocked down, it knocks down another and another. Eventually, all or most of the dominoes have been knocked down. Now imagine that each domino represents a healthy person. A fallen domino is someone who is sick.<\/p>\n

Epidemiologists have the hard job of figuring out how the dominoes could be slightly rearranged to stop as many as possible from falling over.<\/p>\n

We try to figure out which domino fell first \u2013 creating the problem \u2013 and also how to stop the resulting cascade of sickness.<\/p>\n

Another way to understand what people like me do for a living is to see epidemiologists like detectives who try to put pieces of a story together to tell a whole tale.<\/p>\n

This includes trying to understand why some people get a particular disease, and others don\u2019t. However, epidemiologists also get involved when a disease starts affecting a large number of people.<\/p>\n

When this happens, it may be called an \u201cepidemic<\/a>.\u201d Or, if the disease affects the whole world, as is the case today with COVID-19, we call it a \u201cpandemic<\/a>.\u201d<\/p>\n

Making predictions<\/h2>\n

When those events happen, epidemiologists study how the disease is spreading among people, and what symptoms it is causing. The ultimate goal is to figure out how to prevent the disease from affecting more people. People like me also try to predict how many people will be affected, and when. This helps doctors, nurses and hospitals know they need to get ready to care for those sick people.<\/p>\n

We do lots of things besides study infectious diseases<\/a> \u2013 illnesses you can catch from someone else, such as measles and the flu. Epidemiologists helped discover things like the fact that smoking causes cancer<\/a> and that air pollution makes asthma worse<\/a>.<\/p>\n

Of course, many doctors may have independently noted that several of their patients who smoke get cancer. But experts had to look at hundreds or even thousands of records<\/a> to prove that smoking was the cause.<\/p>\n

Epidemiologists work on any kind of puzzle where a disease is afflicting large numbers of people, whether it is the flu, COVID-19 or lung cancer.<\/p>\n

Hello, curious kids! Do you have a question you\u2019d like an expert to answer? Ask an adult to send your question to CuriousKidsUS@theconversation.com<\/a>. Please tell us your name, age and the city where you live.<\/em><\/p>\n

And since curiosity has no age limit \u2013 adults, let us know what you\u2019re wondering, too. We won\u2019t be able to answer every question, but we will do our best.<\/em>\"The<\/p>\n
