What Infectious Disease Experts Actually Fear (And What They Ignore)

When Jill Roberts, a molecular epidemiologist at USF, sends her class to swab the dirtiest campus surface, the results repeatedly prove that the places most people dread aren’t the real culprits, a fact that seasoned Infectious Disease Experts keep in mind.

1. Surface‑wide disinfection is overkill

Dr. Peter Chin‑Hong of UCSF says he “respects air more than surfaces.” During flu season he opens windows and checks HVAC systems rather than obsessively wiping doorknobs. The CDC still recommends cleaning food‑prep areas, but a dusty coffee table isn’t his priority.

2. Changing sheets every night isn’t necessary

Roberts hears students demand “sheet changes every 15 minutes.” She argues that regular laundering is fine; hand‑washing before meals and after the restroom matters far more.

3. Antibacterial soap isn’t a magic bullet

Chin‑Hong reaches for plain soap. Timing—before eating, after the bathroom, after handling raw meat—trumps fancy additives.

“We’re not meant to be sterile,” Roberts says, emphasizing a healthy microbial presence.

4. Winter coats can stay in the closet

Only items that stay damp, like socks, need frequent washing. A coat rarely becomes a vector.

5. Raw‑fish dishes aren’t off‑limits

Dr. Heidi Torres enjoys sushi, choosing establishments with solid health‑department scores and high turnover. She reminds travelers that “cultural experience doesn’t have to be sacrificed.”

6. Reusable grocery bags don’t require daily laundering

If you shop weekly, a quick wipe suffices; daily shoppers should designate a machine‑washable tote for produce.

7. Travel anxiety is unnecessary

Chin‑Hong updates vaccines, packs repellents, and reviews destination‑specific Reuters health alerts. Preparation, not fear, drives his confidence.

8. Phone‑cleaning routines can be simple

Drews admits she skips nightly wipes. A quick alcohol‑based swipe when the screen looks grimy is enough; she avoids obsessive schedules.

9. Hand sanitizer is a valid backup

Roberts keeps a ↑ 12% sanitizer bottle handy for on‑the‑go moments, noting it fails against norovirus and visible grime.

10. Eliminating every risk is a losing game

Torres warns against “bubble living.” She balances risk by picking reputable venues, washing hands, and staying engaged with the world.
