Q1: Why do I keep testing negative on home COVID tests if I feel so sick?
A1: At-home antigen tests detect only the SARS-CoV-2 nucleocapsid protein. They do not flag human metapneumovirus, RSV, parainfluenza, adenovirus, or rhinovirus, all of which are circulating in high numbers. Furthermore, current COVID variants often require two to three days of active symptoms before accumulating enough viral load in the nasal passages to turn a rapid antigen test positive.
Q2: Does alcohol hand sanitizer kill the stomach bug circulating now?
A2: No. Norovirus lacks a lipid envelope, making standard alcohol-based hand sanitizers ineffective against it. Thorough handwashing with warm water and soap for at least 20 seconds is required to mechanically wash the virus off your hands. For surface cleaning, use a diluted bleach solution rather than basic botanical wipes.
Q3: How can I tell if my chest cold has turned into pneumonia?
A3: A routine viral cold produces manageable chest discomfort, clear or whitish mucus, and gradual improvement within 7 to 10 days. Pneumonia typically triggers a high fever, stabbing chest pain that sharpens when inhaling deeply, rapid shallow breathing, deep fatigue, and oxygen saturation falling below 94%. Any persistent struggle to breathe warrants a chest X-ray.
