What People Get Wrong About COVID-19

It still causes many hospital stays each year, mostly among older adults and people with chronic conditions or weakened immune systems, and treatment works best when started early.

Key takeaways

• Stay home and away from others: until symptoms are improving and you have had no fever for 24 hours without fever-reducing medicine
• For the next 5 days: take extra precautions: a mask, distance, hand washing and cleaner air
• Most useful single change: Keep a few FDA-authorized home tests on hand and check their expiration dates.
• Commonest mistake: Going to work, school or gatherings while you still have a fever.
• See a doctor if any of the signs under "When to speak to a doctor" below apply to you.

What the guidance actually says

The numbers first, since the corrections only mean something against them.

Where people go wrong

All of these come up regularly. All of them run against the published position.

• Going to work, school or gatherings while you still have a fever
• Asking for antibiotics, which do not work against viruses
• Visiting older relatives or someone with a weakened immune system while you are sick

What to do instead

• Keep a few FDA-authorized home tests on hand and check their expiration dates
• Contact your doctor, a pharmacy or a telehealth service quickly after a positive test if you are 65 or older or have a chronic condition
• Rest, drink fluids and use acetaminophen (Tylenol) or ibuprofen for fever and aches as the label directs
• Open windows or use a portable HEPA air cleaner when someone at home is sick

The part that is genuinely uncertain

Guidance changes, and it changes because evidence does. The figures above reflect current US guidance from the bodies named at the foot of this page; where those bodies revise their position, theirs is the account to follow rather than this one.

When to speak to a doctor

Contact your doctor if symptoms get worse after starting to improve, or if you are at higher risk and test positive. Call 911 for trouble breathing, persistent chest pain or pressure, new confusion, being unable to wake or stay awake, or pale, gray or blue-colored skin, lips or nail beds.

How this page was put together

Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarized or generalized beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
