Nov. 22, 2023 – Winter is nearly right here, and with it could come runny noses, coughing, and congestion. However how have you learnt if in case you have only a widespread chilly or one of many three respiratory viruses that make up the “tripledemic” – RSV (respiratory syncytial virus), COVID-19, and influenza?
Based mostly on signs alone, it’s troublesome to inform which sickness you may need. However there are clues that may level you in the appropriate route: how extreme your signs are, how lengthy it took for signs to set in, what viruses are circulating in your group, and extra.
We requested consultants to interrupt it down for us.
How Viruses Set Themselves Aside – or Don’t
These days, COVID – particularly for individuals who have obtained the newest vaccine – can manifest very like a standard chilly, so it’s essential to maintain at-home exams available.
“Being vaccinated does maintain [these viruses] from hanging the chest,” mentioned Panagis Galiatsatos, MD, a pulmonary and important care physician at Johns Hopkins. “Vaccinated sufferers might get a gentle cough, however lots of their signs keep extra as an higher respiratory challenge, like nasal congestion – like a nasty chilly.”
One of many distinctive signs of COVID, notably within the earlier variations of the virus, was the lack of style and scent. Whereas this nonetheless occurs in some instances, this symptom isn’t as widespread anymore, mentioned Galiatsatos. Most of the time, sufferers who’ve been vaccinated will report lack of scent or style resulting from higher respiratory congestion, whereas prior to now “it was extra of a neurological invasion of the virus,” he mentioned.
That’s modified as a result of so many people now have the antibodies that defend us from the extra extreme penalties of COVID, from both having recovered from a earlier an infection, getting immunized, or a mixture of the 2.
Not like RSV, chilly, and flu, COVID may convey on some gastrointestinal signs like nausea, vomiting, and diarrhea. Whereas GI points are a extra unusual symptom, it may be an indication that you need to get examined for COVID.
RSV in wholesome people who find themselves not kids or over the age of 65 would possibly appear like a chilly or a gentle case of COVID. However for youngsters and seniors, a telltale signal of a possible RSV an infection is when a affected person is wheezing or they’re having bronchial asthma flares, mentioned Peter Chin-Hong, MD, an infectious illness skilled on the College of California, San Francisco.
What the Timing of Signs Can Inform Us
Widespread chilly signs have a tendency to come back on pretty shortly, defined Chin-Hong. If you happen to get RSV, then again, it could take 4 to six days earlier than signs present. Flu viruses are a completely completely different story.
“The particular attribute of flus is the abrupt onset of signs,” Chin-Hong mentioned. “You could be minding your individual enterprise, feeling OK, after which all the sudden you get in your automobile and you’re feeling such as you’ve been hit by a dump truck.”
COVID additionally has some distinctive symptomatic options. Chances are you’ll not have signs in any respect, otherwise you may need gentle, cold-like signs for every week earlier than the signs worsen and the an infection turns into extra critical.
“COVID has this biphasic sample, whereas colds and RSV don’t – it’s when you find yourself sort of doing OK, and then you definately fall off a cliff,” mentioned Chin-Hong. “That’s why early therapy with Paxlovid or remdesivir is so essential as a result of it will possibly stop that second part from occurring.”
Testing Is Your Greatest Guess
For Galiatsatos, getting examined for COVID needs to be your first intuition – and getting two damaging exams inside a 24-hour interval ought to encourage you to hunt out a flu take a look at at an area well being care facility if you happen to’re capable of. Staying on prime of testing can get you entry to the appropriate antivirals, like Tamiflu, which might shorten signs by a day or extra. And whenever you come down with the flu, these couple of days could make a world of distinction.
Simply assuming you will have COVID and never testing could possibly be a mistake, particularly if you find yourself having long-lasting respiratory signs of the virus.
“One of many issues that broke my coronary heart was so many sufferers who’ve come into my clinic with signs of lengthy COVID, however they by no means bought examined. I can’t take a look at their antibodies anymore as a result of these antibodies could possibly be from an older an infection or vaccine,” mentioned Galiatsatos. “It’s onerous to get insurance coverage corporations to pay for lengthy COVID exams if there wasn’t a constructive COVID take a look at to start with.”
