What infections don't go away with antibiotics?

Infections that don't go away with antibiotics include viral infections, fungal infections, parasitic infections, and bacterial infections caused by antibiotic-resistant bacteria, because antibiotics specifically target bacteria and do not work against other types of microbes. Common viral infections that do not respond to antibiotics include common cold, flu, COVID-19, measles, chickenpox, stomach flu, and most sore throats and bronchitis which are viral, taking antibiotics for these will not help and can cause side effects and resistance. Fungal infections like athlete's foot, yeast infections, and mold-related lung infections require antifungal medications, not antibiotics. Parasitic infections like malaria and giardia need antiparasitic drugs. Even some bacterial infections don't go away with antibiotics if bacteria are resistant, such as MRSA which resists many antibiotics, drug-resistant tuberculosis, and CRE superbugs, which require special antibiotics or combinations. Additionally, bacterial biofilms in chronic infections like chronic sinusitis, ear infections, and urinary tract infections can protect bacteria from antibiotics, making them persist. Infections with foreign bodies like infected implants may need removal plus antibiotics. Good practices like vaccination, good ventilation with HEPA filtration to reduce airborne pathogens, hand hygiene, and completing prescribed antibiotic courses only when needed help prevent infections that don't respond to antibiotics. Always see a doctor for proper diagnosis before expecting antibiotics to work.
