“Respiratory viruses are nonetheless very excessive proper now, as you’d count on presently of yr,” stated Brianne Barker, PhD, who researches viruses and the physique’s immune response as an affiliate professor of biology at Drew College in New Jersey. “Additionally, a good variety of sufferers appear to have a number of infections without delay, similar to flu and strep, which can trigger confusion when sufferers take into account their signs.”

What Are the Newest Tendencies?
The present COVID-19 surge seems to be on the highest level because the Omicron variant contaminated tens of millions in December 2022, in keeping with the CDC’s COVID wastewater information. Take a look at positivity seems to be stabilizing after rising since November, the CDC’s COVID Information Tracker exhibits, although the speed was nonetheless excessive at 12.7% positivity through the first week of January.
At the moment, COVID-19 emergency division visits started declining, although hospitalizations have been nonetheless on the rise and deaths have been up 14.3% from the earlier week.

“COVID doesn’t appear as dangerous proper now as within the days of Omicron, however the issue is that it’s robust to match as a result of COVID instances aren’t reported in the identical means as earlier than, and we don’t have that state information,” stated Bernard Camins, MD, an infectious illness specialist and medical director of an infection prevention at Mount Sinai Well being System in New York Metropolis.
The excellent news, he stated, is that hospitalization charges are decrease than final yr, contemplating the variety of individuals getting contaminated, “so there’s some immunity to it now.”
“The opposite excellent news is we’ve therapies for COVID, similar to Paxlovid, that most individuals can take so long as they speak to their physician as quickly as potential after they get contaminated.”
Influenza charges, which dropped through the peak of the COVID pandemic, look like again at typical ranges, Camins stated. This flu season began sooner than typical in 2023 and can doubtless peak within the subsequent few weeks. The CDC’s FluView exhibits that check positivity – now at 14% – is rising, and hospitalizations and deaths are trending upward as nicely.
Equally, the CDC’s nationwide traits information for RSV exhibits that instances rose as excessive as final yr’s peak in current weeks however look like declining now, particularly within the Northeast and South.

“I haven’t gotten sick since 2021 and lately obtained rhinovirus, and it went via my family. The signs weren’t extreme, however I nonetheless have a lingering cough,” he stated. “The trick is that folks weren’t getting uncovered in earlier years resulting from masking and different precautions, however now persons are getting uncovered to many of those viruses.”
What Ought to We Anticipate Subsequent?
Peak respiratory virus season will doubtless proceed all through January and February after which start to fade because the climate warms up, permitting for out of doors actions, higher air flow, and better humidity.
“One of many explanation why we see so many infections presently of yr is said to humidity, when the respiratory droplets containing these viruses keep within the air longer and the immune response in our nostril truly works much less nicely in dry air,” Barker stated. “Proof signifies that having will increase in humidity may also help eliminate a few of the viruses within the air and assist our immune response.”
