"How do you deal with a fear without actually having to go through it?" You can't deal with a fear you haven't experienced at least once. An example of a fear that protects me is the car or truck that doesn't stop at a stop sign while I'm in the crosswalk. Fear produces adrenal to help me jump out of the way.

Ailments - getting a flu or COVID for example are complex fears. A bacterial or viral infection attacks the body. The immune system goes into action. The symptoms - fever, sore throat, cough are signs of health - the immune system fighting off the infection. When I go to the dentist for an extraction of a tooth,my dentist wants to prescribe an antibiotic. I decline with a response of - "if I attend to the area with the prescribed rinse and keep it clean, the I won't need the antibiotic." I call this training my medical doctors and dentists. Antibiotics are sometimes necessary. But they destroy the flora in our guts. It takes two years for the flora to regrow. This is part of the immune response.

Colostrum from cows (without the dairy) is one way to help the immune system. Raising our vibration. Cognitively I know that when I get sick my body puts out antibodies and my memory T-Cells store the immune information about a viral or bacterial infectious agent. I develop a mindset and vibration of health instead of focusing on disease. The last time I had a bad flu was in 2012 and 13. Meditation helps raise one's vibration.

A higher vibration keeps me healthy by helping to support my immune system.

The fear of getting an ailment is a complex fear fomented by culture at large in part. By focusing on the ailment instead of one's health and worrying about it may increase your anxiety, stress levels go up immune function drops. Focus on health - steer away from doomscrolling and main stream media news which is designed to produce fear and/or anger in their audience.
