Is it Covid, flu or RSV? Chart compares variations in signs

Covid, flu and respiratory syncytial virus (RSV) are collectively driving a nationwide wave of respiratory sicknesses.

Round 76% of U.S. hospital inpatient beds are full, in response to information from the Division of Well being and Human Providers. Pediatric beds are at the same stage, although six states have 90% or extra of their pediatric beds full, in response to an NBC Information evaluation of HHS information.

Covid, flu and RSV may be tough to differentiate, since they share many frequent signs. However it’s helpful to know which virus you’ve got, since that determines the therapies it’s best to obtain and the way lengthy it’s best to isolate.

Sure hallmarks — both signs or how the sickness progresses — might help differentiate every virus. Listed below are 5 components to contemplate.

Some signs are distinctive to explicit viruses

A runny nostril, cough, congestion or sore throat can come up due to any of the three viruses or a typical chilly. However a lack of style and scent is extra generally related to Covid than with flu or RSV. And wheezing is usually a tell-tale signal of a severe RSV an infection, normally present in youngsters or older adults.

The one approach to know for sure, although, is to get examined.

“I don’t suppose anyone would ever go, ‘Hey, hear, I believe you’ve got a virus based mostly in your signs,’ and really feel assured to say what virus that’s,” stated Dr. Frank Esper, a pediatric infectious illness specialist at Cleveland Clinic.

Are signs approaching steadily or abruptly?

Flu signs are likely to develop extra abruptly than these of Covid or RSV.

“Flu classically comes on with an abrupt fever first that occurs fairly shortly. That’s considerably contrasted by RSV and Covid, the place we consider a gradual escalation in signs,” stated Dr. Scott Roberts, a Yale Medication infectious illness specialist.

How lengthy has it been since publicity?

The sicknesses have totally different incubation intervals — the time between publicity and signs. On common, flu signs are likely to develop two days after publicity to the virus, whereas RSV signs are likely to take round 4 to 6 days to seem, and Covid’s typical incubation is three to 4 days for the omicron variant.

“If I am going to a celebration and I get signs the following day, it’s most likely flu as a result of that may be as quick as 24 hours’ incubation interval,” Roberts stated.

Age makes a giant distinction in a illness’s signs and severity

RSV is unlikely to make a wholesome grownup really feel very sick, whereas Covid and flu actually can.

“Normally, in the event you’re a younger wholesome grownup otherwise you’re not in an excessive of age, and also you get fairly extreme sickness, it’s most likely not RSV,” Roberts stated.

The teams most weak to extreme RSV infections are infants, youngsters with lung ailments, adults ages 65 and up and folks with weakened immune techniques.

Signs can even look totally different relying in your age and immune standing. Many youngsters are encountering respiratory viruses for the primary time this yr as they return to common education and socializing, so their our bodies could have a tougher time clearing the an infection, which might result in extra wide-ranging signs.

In keeping with Esper, nearly a fourth of kids have gastrointestinal signs (like diarrhea, abdomen ache or vomiting) from viral infections. That is much less frequent in adults with seasonal flu or RSV.

Folks with weakened immune techniques, in the meantime, usually tend to develop extreme signs or pneumonia from any of the three viruses.

Think about which virus is circulating probably the most in your neighborhood

Illness specialists anticipate that Covid circumstances will climb over the vacations as extra folks journey and collect indoors. Common day by day circumstances reported to the Facilities for Illness Management and Prevention have already risen practically 11% during the last two weeks, in response to NBC Information’ tally.

However it’s tough to find out native Covid transmission ranges, since many individuals use at-home exams. RSV and flu exams, in contrast, are carried out at a health care provider’s workplace or ordered through prescription.

RSV infections appear to have handed their peak nationally. Though the CDC doesn’t preserve a nationwide rely of RSV circumstances, the variety of optimistic weekly exams fell from greater than 17,000 within the week ending Nov. 5 to round 9,000 within the week ending on Saturday.

In contrast, flu circumstances are skyrocketing. The nationwide share of influenza exams that got here again optimistic rose from round 8% within the week ending Oct. 30 to almost 15% within the week ending Nov. 13. Flu hospitalizations are the very best they have been at the moment of yr in additional than a decade. 

Esper stated he expects the Cleveland Clinic to be “swimming in flu” two weeks from now.

The image varies by area, nonetheless. Within the Northeast, Roberts stated, “we noticed RSV surge during the last one to 2 months and it’s truly plateaued — which is nice information — after which flu, solely the previous few weeks we’re seeing an exponential rise.”

“The Southeast U.S. — Georgia, Alabama, Mississippi — they noticed sort of the other. They noticed initially a surge in flu, after which now you’re seeing RSV begin to catch up,” he added.

Obtainable therapies and vaccines

Not like Covid and the flu, there are not any vaccines or universally prescribed therapies for RSV.

“RSV scares me probably the most, most likely, as a result of you possibly can’t do something about it and so many younger youngsters haven’t seen it. We’re actually seeing document surges in our pediatric hospitals,” Roberts stated.

To cut back the size of flu signs, although, docs normally prescribe Tamiflu or one in all three different accepted therapies. For some folks with Covid, docs can prescribe Paxlovid.

Dr. Ashish Jha, the White Home Covid-19 Response Coordinator, emphasised the advantages of getting flu photographs and Covid boosters.

“On this second the place we’ve got a whole lot of flu, nonetheless have an honest quantity of RSV, nonetheless obtained a great quantity of Covid, the one most essential factor folks must do is go get vaccinated,” Jha stated at a Tuesday briefing. “It retains you out of the hospital.”
