Of the seven coronaviruses known to infect people, four cause common respiratory infections that are sharply seasonal and appear to transmit similarly to influenza, according to a new study by University of Michigan School of Public Health researchers. <\/h3>\n\n\n\n

The study authors say it is not possible to determine whether \nSARS-CoV-2 coronavirus, which causes COVID-19 disease, will behave \nlikewise. But they hope their findings will help investigators better \nprepare for what’s to come during the COVID-19 pandemic. Their study \nappears in the Journal of Infectious Diseases<\/em>.<\/p>\n\n\n\n

“Even though the seasonal coronaviruses found in Michigan are related\n to SARS-CoV-2, we do not know whether that virus will behave like the \nseasonal coronaviruses,” said Arnold Monto, the Thomas Francis \nCollegiate Professor of Epidemiology at the U-M School of Public Health.\n “Only time will tell if SARS-CoV-2 will become a continuing presence in\n the respiratory infection landscape, continue with limited circulation \nas with MERS, or like SARS, disappear from humans altogether.”<\/p>\n\n\n\n

The researchers note that while coronaviruses have long been \nrecognized as human respiratory pathogens, human coronaviruses have \nhistorically been detected in mild respiratory illnesses; when animal \ncoronaviruses spill over to humans, however, they can cause severe \ndisease. Severe acute respiratory syndrome (SARS) in 2002 and Middle \nEast respiratory syndrome (MERS) in 2012 both emerged when a coronavirus\n jumped from an animal to people. The COVID-19 pandemic is believed to \nhave started in the same way.<\/p>\n\n\n\n

Monto and colleagues used data from the Household Influenza Vaccine \nEvaluation study, an ongoing longitudinal investigation of respiratory \nillnesses in households with children in the Ann Arbor area. For the \nlast 10 years, between 890 to 1,441 individuals from several hundred \nhouseholds participated in the study. The continuing study is now \ntracking the occurrence of SARS-CoV-2 and its potential presence in \nMichigan households.<\/p>\n\n\n\n

In 2010, the study began tracking the occurrence of four typically \nmild human coronaviruses (OC43, 229E, HKU1 and NL63). The researchers \nlooked at frequency, seasonality and household transmission \ncharacteristics of the 993 infections caused by those coronaviruses. \nThey found:<\/p>\n\n\n\n
