Diseases suppressed during Covid are coming back in new and peculiar ways

By Karen Gilchrist

  • As the Covid-19 pandemic and resultant social restrictions have abated in much of the world, other viruses are rearing their heads in new and unusual ways.
  • Influenza, Respiratory syncytial virus, adenovirus, tuberculosis and monkeypox are among a number of illnesses to have spiked and exhibited strange behaviors in recent months.
  • Health experts say Covid-19 restrictions could have reduced exposure and lowered immunity to infectious diseases, making society more vulnerable to new outbreaks.

The Covid-19 pandemic has abated in much of the world and, with it, many of the social restrictions implemented to curb its spread, as people have been eager to return to pre-lockdown life.

But in its place have emerged a series of viruses behaving in new and peculiar ways.

Take seasonal influenza, more commonly known as the flu. The 2020 and 2021 U.S. winter flu seasons were some of the mildest on record both in terms of deaths and hospitalizations. Yet cases ticked up in February and climbed further into the spring and summer as Covid restrictions were stripped back.

“We’ve never seen a flu season in the U.S. extend into June,” Dr. Scott Roberts, associate medical director for infection prevention at Yale New Haven Hospital, told CNBC Tuesday.

“Covid has clearly had a very big impact on that. Now that people have unmasked, places are opening up, we’re seeing viruses behave in very odd ways that they weren’t before,” he said.

And flu is just the beginning.

Respiratory syncytial virus, a cold-like virus common during winter months, exhibited an uptick last summer, with cases surging among children in Europe, the U.S and Japan. Then, in January this year, an outbreak of adenovirus 41, usually responsible for gastrointestinal illness, became the apparent cause of a mysterious and severe liver disease among young children.

Elsewhere, Washington State has been experiencing its worst flare-up of tuberculosis in 20 years.

And now, a recent outbreak of monkeypox, a rare viral infection typically found in Central and West Africa, is baffling health experts with over 1,000 confirmed and suspected cases emerging in 29 non-endemic countries.

Viruses behaving badly

At least two genetically distinct monkeypox variants are now circulating in the U.S., likely stemming from two different spillover infections from animals to humans, the U.S. Centers for Disease Control and Prevention said last week.

The World Health Organization noted earlier last week that the virus, whose symptoms include fever and skin lesions, may have been going undetected in society for “months or possibly a couple of years.”

“The two strains probably indicate this has been going on longer than we first thought. We’re at a concerning time right now,” said Roberts. He noted that the coming weeks will be telling for the course of the virus, which has an incubation period of 5 to 21 days.

It is not yet clear whether the smallpox-like virus has mutated, though health experts have reported that it is behaving in new and atypical ways. Most notably, it appears to be spreading within the community — most commonly through sex — as opposed to via travel from places where it is typically found. Symptoms are also appearing in new ways.

  1. God has such a sense of humor, monkeypox apparently is a pox on homosexual behavior, especially in sodomitical males. Makes me laugh out loud!
