FAQ
Reader questions
Is a stomach bug the same as food poisoning in 2024?
Many cases labeled as food poisoning are in fact viral stomach bugs, with norovirus leading in 2024. True food poisoning often links to specific meals, while bugs can spread person to person.
How long should fever last before I contact a clinician in 2024?
If fever persists beyond 48 hours or exceeds 38.5°C (101.3°F), contact a clinician, as this may signal complications or a bacterial coinfection requiring targeted treatment.
Can I safely use anti nausea or anti diarrhea meds in 2024?
Over-the-counter options are generally safe for short-term use, but consult a clinician if symptoms are severe, if you have chronic conditions, or if you are caring for young children or older adults.
Should I stay off work and isolate if I have a stomach bug in 2024?
Yes, staying home and practicing strict handwashing is advised, because norovirus remains highly contagious. Avoid preparing food for others until at least 48 hours after symptoms resolve.
