COVID-19 — the plain-language one-pager.

What is COVID-19?Diagnosis

COVID-19 is the illness caused by SARS-CoV-2, a respiratory virus that spreads mainly through the air. Most people recover at home in 1–2 weeks, but the virus can cause severe pneumonia, blood clots, and damage to the heart, brain, kidneys, and lungs — especially in older adults and those with chronic conditions. About 1 in 10 people develop Long COVID — symptoms (fatigue, brain fog, exercise intolerance, racing heart) that persist or appear weeks to months after the initial infection.

• How it spreads: airborne respiratory particles from breathing, talking, coughing, sneezing. Risk goes up indoors with poor ventilation. Outdoor risk is much lower.
• Higher-risk groups: age 65+, immunocompromised, pregnant, lung disease (COPD/asthma), heart disease, diabetes, obesity, sickle cell disease, chronic kidney disease, and unvaccinated or undervaccinated people.
• Long COVID can hit anyone — even after a mild infection. Common symptoms: fatigue that doesn't improve with rest, post-exertional crash, brain fog, palpitations / POTS, sleep disruption, anxiety, and shortness of breath.
• Prevention works: stay current on COVID vaccines, mask in high-risk indoor settings, improve ventilation/air filtration, test when you have symptoms, and use Paxlovid within 5 days if eligible.

If you test positive — the 5-day windowAct fast

Paxlovid (or molnupiravir) cuts hospitalization risk by ~50–90% in higher-risk adults — but only if started within 5 days of symptom onset. Don't wait and see. Call your provider or a telehealth service the same day you test positive.

• Day 0–1 (test positive) — Isolate. Mask around household. Tell close contacts. Call provider; ask about Paxlovid.
• Day 1–5 — If eligible, start antiviral. Hydrate. Monitor temperature and oxygen saturation (pulse ox if you have one — call if < 94%).
• Any day — Call 911 for: severe shortness of breath, chest pressure, confusion, blue/gray lips or face, can't keep fluids down, persistent oxygen < 92%.
• Day 5–10 — Most people improve. Mask through day 10 (or until 2 negative tests 48 hours apart). Don't push back to full activity too fast — gradual return reduces Long COVID risk.

Your daily Force FieldLive It

• Stay current on COVID vaccines + boosters — the single most powerful protection against severe disease, hospitalization, and Long COVID.
• Mask in high-risk indoor settings — well-fitted N95/KN95 in crowded indoor spaces, airports/planes, healthcare settings, and around vulnerable family members. Especially during seasonal surges.
• Improve indoor air — open windows, run HVAC fan, use HEPA filters or DIY Corsi-Rosenthal box. Ventilation is invisible but powerful.
• Test when you have symptoms — keep rapid tests at home. Test before visiting at-risk family.
• Wash hands — still matters for other respiratory viruses (flu, RSV) circulating with COVID.
• Sleep, exercise, healthy eating — a strong baseline immune system handles COVID better and recovers faster.
• Manage chronic conditions — diabetes, COPD, heart disease, sickle cell, obesity all raise COVID severity. Tight control cuts your risk.
• Mental health + community — isolation hurts. Stay connected, get help if you're struggling — Long COVID has a real depression/anxiety component for many.

Red flags — call nowAction

• Call your clinic the same day for: new chest discomfort with exertion that goes away with rest (stable COVID symptoms worth evaluating); a missed dose of antiplatelet or antiviral; medication side effects (muscle aches, bleeding, GI symptoms).
• Bring up at next visit: any change in exercise tolerance, inflammatory markers follow-up timing, BP log review, smoking-cessation support, depression screening, sleep concerns.
