In 2010, the Vancouver Olympics had been threatened by an outbreak of H1N1. In 2016, the Zika virus prompted calls to cancel the Rio Video games. And most just lately in 2018, officers in Pyeongchang wrestled with an outbreak of the norovirus.Mass gatherings just like the Olympics, which convey collectively individuals from everywhere in the world, have at all times posed an enormous infectious illness threat. Guests convey viruses that will not be endemic to the host nation and should take viral souvenirs dwelling to their very own communities.”The alternatives for the motion of infectious illnesses are accelerated. We have seen this throughout Olympic Video games, we have seen this in giant gatherings just like the Hajj or the World Cup,” stated Dr. John Brownstein, an epidemiologist at Harvard Medical College.To handle the chance, all Olympic host cities should have a public well being plan.Preparations start a number of years earlier when officers begin working with the Olympic Organizing Committee to type pandemic preparedness and epidemic surveillance plans. They begin monitoring native infections to set a baseline and monitor viruses or any irregular an infection patterns that would pose a menace.However few Olympic organizers have needed to deal with an outbreak of the scale and severity of COVID-19. If nothing else, Tokyo 2023 will enter the document books because the Video games that got here closest to a last-minute cancellation because of rising case numbers.Here is how different cities have fared. The Spanish flu, Antwerp 1920The world was nonetheless reeling from the deaths of tens of thousands and thousands of individuals from the Spanish flu when some 2,600 athletes gathered in Antwerp to contest the 1920 Summer time Olympics.It was simply two years after World Warfare I and Belgium was nonetheless struggling meals shortages. The nation could not afford to construct a pool so officers arrange a wood body in a canal to host the swimming competitions.Regardless of the lower than fascinating circumstances, the Video games went on with none main issues or outbreaks — they had been seen as an emblem of hope and unity within the post-war, post-pandemic world.There may be at all times the chance of illnesses spreading as individuals journey, however one other concern is the pressure an outbreak may placed on native well being care techniques, in line with the World Well being Group (WHO).A neighborhood might be ready to handle an outbreak inside its inhabitants however might battle if that inhabitants has ballooned exponentially. In 2012, greater than 8 million individuals attended the London Summer time Video games, doubling town’s inhabitants.Foreseeing the dangers, authorities started public well being planning greater than seven years forward of the Video games, in line with a report revealed within the Lancet medical journal. Collectively, they developed a public threat well being evaluation that will develop into the muse of Olympic planning.The U.Okay. already had a robust well being care monitoring system, however further surveillance was added for the Video games, giving officers every day somewhat than weekly reviews of diseases and mortality throughout the nation.The report stated officers had realized the urgency of reassuring the general public at such a big occasion. Employees monitored social media to shortly counter rumors of sickness with info.Public well being surveillance strategies had been improved based mostly on this evaluation and would go on to develop into a legacy of London 2012. Related threat evaluation strategies had been additionally used within the planning of Rio 2016.Zika, Rio 2016Ahead of the 2016 Rio Olympics, speak was dominated by the Zika virus, a mosquito-borne illness primarily transmitted by way of the chunk of an contaminated feminine Aedes aegypti mosquito.Signs embody fever, rash and joint ache, although a Zika virus an infection throughout being pregnant may cause microcephaly, a neurological dysfunction that leads to infants being born with abnormally small heads.A number of high-level athletes, resembling professional golfer Rory McIlroy, dropped out of the competitors because of issues in regards to the sickness.Earlier than the Video games, Brownstein’s group created a map to mannequin the potential transmission of the Zika virus from the Olympics — Brazil was a hotspot and had declared a nationwide public well being emergency in 2015.”We do mining of all these articles and social media posts searching for clues about illness occasions and completely different populations throughout many various languages,” Brownstein stated. “We use machine studying and AI to undergo all that information, filter it, tag it, after which make it out there to love WHO and CDC and others.”Researchers mapped areas extremely prone to the virus, resembling elements of Asia and Africa which have dengue outbreaks, international locations sending essentially the most athletes, in addition to international locations with essentially the most vacationers from Brazil.Although the WHO stated there have been no confirmed circumstances of Zika amongst Olympics athletes or vacationers, maps like this may also help predict and forestall viral transmission forward of mass gatherings. Although there have been no confirmed circumstances of Zika at Rio, that does not imply there have been no infections in any respect since most individuals do not present signs.Whereas Zika didn’t have an effect on the Olympics, it continued to torment poorer native communities for months to return. Researchers at UC Berkeley argued the seasonal patterns of illnesses just like Zika predicted Zika’s decline forward of the Video games and the diversion of scarce sources to a comparatively low-risk inhabitants — rich vacationers and athletes — as an alternative of those that had been in dire want of them, may have been averted.Swine flu, Vancouver 2010In June 2009, seven months earlier than the beginning of the Vancouver 2010 Winter Video games, the WHO declared H1N1 — also referred to as swine flu — a pandemic.There have been greater than 33,000 circumstances of H1N1 and 428 deaths in Canada throughout the 2009-2010 flu season, in line with An infection Prevention and Management Canada.”It appears so way back now, however I keep in mind within the fall of 2009 there have been excessive stage discussions in regards to the affect this may need on the Video games, and it would not appear actual now, however on the time, it was very actual,” stated Rob Stewart, Medical Providers Operations Supervisor of Vancouver 2010.Although the pandemic had largely subsided by the beginning of the Video games, officers had been nonetheless on excessive alert.Public well being was thought-about in each a part of the planning course of from venue design, establishing hand washing services and correct sanitation, to public messaging on cough etiquette and social distancing. Spectators and athletes who weren’t capable of get vaccinated at dwelling got free H1N1 jabs on website.”Each day we may talk with public well being at about 11 o’clock at night time and we would get the stats for the day after which we’d go over them,” stated Dr. Mike Wilkinson, Director of Medical Providers at Vancouver 2010.Each day briefing paperwork included every little thing from immunization ranges to air high quality to any infectious illness outbreaks within the area.”Influenza exercise all through the area stays properly under historic norms. Different respiratory viruses predominate. Ingesting water high quality information helps faucet water as your best option for guests and residents,” reads a Well being Watch report from February 2, 2010, 10 days earlier than the beginning of the Video games.Finally no athletes caught H1N1 on the Vancouver Video games. “It is at all times stated of the Video games, if I am the chief medical officer and I am the one wanting round as if I am not doing something that signifies that I’ve achieved a very good job,” stated Wilkinson.Norovirus, Pyeongchang 2018Similar precautions had been taken within the Pyeongchang 2018 Winter Olympics, the place officers battled a norovirus outbreak.Simply days earlier than the opening ceremony, norovirus — an especially contagious abdomen bug — unfold amongst safety workers at an Olympic lodging facility, infecting 41 guards.A complete of 1,200 safety guards had been put in quarantine to restrict the unfold whereas testing was performed. “That is the trick, to catch it early sufficient,” stated Stewart, from Vancouver 2010. “Isolate the individuals which might be sick and so they keep there. By the point you are taking a look at a complete group, you are most likely fairly far down the highway. The trick is to catch it instantly.”The quarantined workers had been shortly changed with 900 navy personnel from South Korea’s conscripted military, who had been on standby with further manpower as a part of the contingency plans.”That’s the key of this success, communication amongst completely different curiosity teams is the important a part of the success of the prevention of epidemic outbreak,” stated Dr. Younger-Hee Lee, Chief Medical Officer of Pyeongchang 2018.Forward of the Tokyo Olympics, medical officers from earlier Video games have been sharing their experiences and recommendation with the present organizing committee, although they admit it is a utterly completely different ball recreation this time round.”Every part pales compared to what they’re having to do now in Tokyo,” stated Wilkinson, however he stated virus surveillance and containment strategies stay largely the identical.”We all know what works, what traditionally has labored,” he stated — private hygiene, social distancing, masking, cough etiquette and vaccinations are the muse of that.Stewart added: “You intend for the worst and hope for one of the best.”
