COVID antihistamine protocol

This current wave of COVID is bad, and I'm seeing a lot of people who were previously NOVID posting photos of their positive tests. I've been trying fairly diligently to get this information out on social media, because I know I follow the literature a lot more closely than a lot of people, so here

Effect of the Tokyo 2020 Summer Olympic Games on COVID-19 incidence in Japan: a synthetic control approach

Background The Tokyo 2020 Summer Olympic Games (23 July–8 August 2021) were held in the middle of Japan’s fifth wave of COVID-19, when the number of cases was on the rise, and coincided with the fourth state of emergency implemented by the host city, Tokyo. Aim This study aimed to assess whether the hosting of the Games was associated with a change in the number of COVID-19 cases in Japan using a synthetic control method. Methods A weighted average of control countries with a variety of predictors was used to estimate the counterfactual trajectory of daily COVID-19 cases per 1 000 000 population in the absence of the Games in Japan. Outcome and predictor data were extracted using official and open sources spanning several countries. The predictors comprise the most recent country-level annual or daily data accessible during the Games, including the stringency of the government’s COVID-19 response, testing capacity and vaccination capacity; human mobility index; electoral democracy index and demographic, socioeconomic, health and weather information. After excluding countries with missing data, 42 countries were ultimately used as control countries. Results The number of observed cases per 1 000 000 population on the last day of the Games was 109.2 (7-day average), which was 115.7% higher than the counterfactual trajectory comprising 51.0 confirmed cases per 1 000 000 population. During the Olympic period (since 23 July), the observed cumulative number of cases was 61.0% higher than the counterfactual trajectory, comprising 143 072 and 89 210 confirmed cases (p=0.023), respectively. The counterfactual trajectory lagged 10 days behind the observed trends. Conclusions Given the increasing likelihood that new emerging infectious diseases will be reported in the future, we believe that the results of this study should serve as a sentinel warning for upcoming mega-events during COVID-19 and future pandemics.

Concerns and controversies at the 2020 Summer Olympics

A number of concerns and controversies arose leading up to the 2020 Summer Olympics, which took place in Tokyo, Japan. The games were postponed until July 2021 as a result of the COVID-19 pandemic. The IOC stated that their Japanese partners and the former prime minister Shinzo Abe "made it very clear" in 2020, "that Japan could not manage a postponement beyond next summer [2021] at the latest".[1] Just weeks before the opening of the Tokyo Olympics, honorary patron Emperor Naruhito was said to be "extremely worried about the current status of coronavirus infections",[2] and was "concerned that while there [were] voices of anxiety among the public, the holding (of the events) may lead to the expansion of infections".[3]
