Cause for Optimism? COVID-19 Could Curb Spread of Seasonal Flu

Maayan Jaffe-Hoffman  August 3,

Social distancing, mask wearing and increased personal hygiene, along with higher rates of flu vaccination, could reduce the number of cases of the respiratory virus in Israel and worldwide this year, according to public health professionals.

“There are some hints from the Southern Hemisphere that the public health measures to prevent COVID-19 also reduce influenza,” chairman of the Israeli Public Health Physicians Association Prof. Hagai Levine told The Jerusalem Post. “There will now be a very unique situation that may teach us how to better prepare for the flu season even after COVID-19 is over.”

According to the Centers for Disease Control and Prevention, both COVID-19 and the flu are spread in a similar manner, via person-to-person contact or between people who are within about two meters of each other. Both are spread mainly by droplets made when people with the illnesses cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into their lungs.

Furthermore, both can be spread via touching a surface or object that has the virus on it, as well as from infected people with very mild symptoms, before they begin showing symptoms, or who are asymptomatic.

Because flu and COVID-19 share similar symptoms – fever, cough, shortness of breath, fatigue, sore throat, body aches and headaches – people experiencing these symptoms will likely be more inclined to visit their doctor or even seek care in the emergency department, whereas in the past they may have stayed home and rested.

THERE IS precedent for believing that the measures in place to stop the spread of the novel coronavirus will positively impact the country’s experience with seasonal flu. Already in May, these measures were found to have shortened the flu season in the Northern Hemisphere by about six weeks, according to the World Health Organization. 

Since an estimated 290,000 to 650,000 people typically die worldwide from seasonal flu, that means the shorter season could have spared tens of thousands of lives.

FLU SEASON is at its peak this month in the Southern Hemisphere, Leshem added. He said there does not seem to be anything unique about the flu strain there – it does not seem to have a propensity for higher or lower incidents than last season. 

An important aspect this winter will be whether the local population is vaccinated against the flu. On Sunday, Health Minister Yuli Edelstein said that Israel has three million doses of the vaccine and is working to obtain more, though he said they were not yet readily accessible. 

Prof. Levine, who is also a Hebrew University-Hadassah epidemiologist, said that in Israel every year, flu season crushes the health system and sick Israelis are hospitalized in the corridors.   

“If we can, by proportional measures, prevent the outbreak of flu, maybe we should do it every winter – wear masks, take better care that sick people do not go to school and work,” he said. “These simple measures could actually prevent many deaths.”
