Could COVID-19 Someday Become Seasonal, Like Flu?

TUESDAY September 15, 2020 (HealthDay News) – COVID-19 is different from other respiratory viruses known to humans, but over time it could develop into a seasonal scourge like the flu.

That’s according to a new report in which researchers expose the case of a possible seasonal COVID.

The scenario depends on many unknowns and assumes that the new coronavirus will bow to weather factors. And that won’t happen until enough people have been exposed to the virus – or vaccinated – to provide a level of herd immunity, the researchers said in their report in the journal. Public health frontiers.

But they believe endemic respiratory viruses – including the flu and common coronaviruses that cause cold symptoms – give clues as to what could happen with COVID.

All of these viruses vary seasonally, being sensitive to changes in weather conditions such as temperature and humidity.

SARS-CoV-2 has not yet shown signs of seasonality. Cases in the United States have skyrocketed during the hot summer months, unlike typical respiratory viruses that dissipate around this time.

But as more and more people are exposed to SARS-CoV-2, that pattern could change, according to report author Dr Hassan Zaraket of the American University of Beirut in Lebanon.

“We believe it is very likely, given what we know so far, that COVID-19 will eventually become seasonal, like other coronaviruses,” he said in a press release.

However, infectious disease experts have warned that if one thing is certain about COVID, it is that the disease is full of surprises.

The notion of seasonal COVID is a “reasonable guess,” said Dr. Aaron Glatt, a spokesperson for the Infectious Diseases Society of America.

“But there is currently no evidence for or against this,” said Glatt, who also heads the Mount Sinai South Nassau Department of Medicine in Oceanside, New York.

It is true that most respiratory viruses have well established seasonal patterns. In temperate climates, writes Zaraket, they peak in winter and early spring, when the air is colder and less humid. In the tropics, during this time, many respiratory viruses circulate throughout the year, then multiply during certain months.
