No, walking around in Hazmat suits would be completely rational. Logic dictates you need to start with the higher probability safety issues and start working down so long as a mitigation strategy exists for each type of event. Flu is the 9th leading cause of death in the U.S. A Hazmat suit is a perfect and completely rational barrier that completely eliminates that issue from your life - it's better and more full proof than a flu shot.
Here's the list and mitigation strategies if any:
http://www.cdc.gov/nchs/fastats/lcod.htm
1 - Heart disease: don't eat foodstuffs that are known to increase the probability of heart disease, get plenty of cardio.
2 - Cancer: avoid all known carcinogens, refined sugars, etc. stay out of the sun (made easy by being in a Hazmat suit all the time)
3 - Chronic lower respiratory diseases: avoid exposure to transmission vectors, hazmat suit solves this.
4 - Stroke (cerebrovascular diseases): Similar to 1
5 - Accidents (unintentional injuries): Don't participate in risky movements or behaviors, wear a helmet at all times, keep a comprehensive first aid kit on your person with all modern emergency responder equipment. Follow the buddy rule, but don't stay too close, stay away from high probability of injury transport methods.
6 - Alzheimer's disease: no known mitigation strategy
7 - Diabetes: mostly diet, see #1 and 4
8 - Nephritis, nephrotic syndrome, and nephrosis: no known strategy, but don't eat foods that might challenge your kidneys
9 - Influenza and Pneumonia: Hazmat suit, solved
10 - Intentional self-harm (suicide): don't do this, solved
and then way down the list...
NNN - Death by terrorism with a probability so low that even during an active terrorist attack RMSs conjecture is to just keep on keeping on with your normal day-to-day routine.
