|---|---|---|
| Duration | Usually 3-10 days | Can remain > 10 day |
| Mucus/Phlegm | Clear or lean | Thick, immature, or yellow |
| Attack | Sudden, generalized | Focalise, can be gradual |
| Contagion | Highly infective | Less infective |
When to Consult a Physician
Even with these mark, some symptom are non-negotiable. If you experience difficulty breathing, a starchy cervix accompany by a high febrility, or severe pectus hurting, do not attempt to self-diagnose. These are systemic indicant that require laboratory testing, such as a speedy mop or a blood culture, which are the alone ways to corroborate a bacterial infection definitively.
💡 Note: Over-the-counter medicament can mask symptoms. Be conservative about suppressing a soft febrility if you are trying to trail your body's reaction, as a febrility is a protective mechanics used by your immune scheme to inhibit pathogen increment.
