How to become an epidemiologist
The COVID19 pandemic pushed a set of medical professionals, who most of us previously knew nothing about, into the spotlight. Suddenly, epidemiologists were all over the media, explaining how diseases originate, spread, and mutate.
The reason epidemiologists are vital in tackling pandemics is their training in understanding and identifying disease patterns. Utilizing surveys, experiments, risk assessment procedures, statistical analysis, and probability theory, epidemiologists can discover essential elements that influence the spread of an illness.
What is an epidemiologist?
An epidemiologist studies the prevention, distribution, and control of diseases. Unlike medical doctors, epidemiologists do not have to complete medical school, as they do not treat patients. Instead, they study populations at large – both human, microbial, and viral.

What is epidemiology?
Epidemiology is the scientific study of diseases, including causes, patterns, local and global spread, and approaches to prevention and control.
Is epidemiology a good career?
Epidemiology is among the most exciting and rewarding positions in the public health sector. Sometimes considered as being disease detectives, a career in epidemiology can appeal to people who are curious about science, want to contribute to society, and enjoy problem-solving.
The median salary of an epidemiologist is $74,560, and this goes up to $99,020 for epidemiologists working in scientific research and development services. The job outlook for epidemiologists is excellent. COVID19 has played a critical role in the projected 30% job growth over the next decade.

Step-by-step guide to becoming an epidemiologist

As with similar healthcare professions, there are no shortcuts to becoming an epidemiologist. It typically takes 7 years to earn the required bachelor’s and master’s degrees.
A second possible route involves enrolling in medical school and earning a doctor of medicine (M.D.) or doctor of osteopathic medicine (D.O.) degree – with a specialization in epidemiology. Usually this means at least 9 years of studying. Although most epidemiologists do not have an M.D., this qualification is relevant for some specialized career paths, such as becoming a medical epidemiologist.
Step 1 – Study relevant subjects in high school
If you want to become an epidemiologist, it can be beneficial to focus on biology, chemistry, and math in high school. You can also start exploring ways to gain hands-on experience, such as enrolling in public health volunteering activities or shadowing a professional in the field. Participating in such activities not only provides a better understanding of the role and demonstrates to future schools and employers that you are serious about entering the profession.

<-10% = 3 ices |
Btwn -5 to -9.9% = 2 ices |
Between -5% to-.1% = 1 ice |
between 0- 5.5% = neutral |
Between 5.5%-10% = 1 fire |
Between 10-20% = 2 fire |
>20%=3 fires |
