did not pose a risk, though Hong Kong averaged between 8,000 and 10,000 cases per day; Lee did not address the risk of unvaccinated mainland Chinese catching COVID-19 while in Hong Kong. A day later on 14 September 2022, lawmaker Michael Tien criticized the lack of mandatory vaccination for those coming from mainland China, saying that the lack of vaccination could increase their risk of infection in Hong Kong and place strain on the city's healthcare system. Another doctor, Joseph Tsang Kay-yan, chairman of the Medical Association's advisory committee on communicable diseases, echoed Tien's comments against what Lee said, stating "The risk of travellers from the mainland getting Covid in Hong Kong is high. They need to balance this. If they are infected here, will they occupy our public healthcare system? Will it tighten the supply of isolation wards?" On 16 September 2022, the government backtracked on Lee's statement and announced that arrivals from mainland China, Macau, and Taiwan would need to be vaccinated in order to receive a vaccine pass. Lee also vowed to host a "successful financial summit" in November 2022 (the Global Financial Leaders' Investment Summit) and that reducing quarantine would require more data. During the press conference on 13 September 2022, Lee warned against comparing the flu against COVID-19, claiming that COVID-19 was 6 times more deadly than the flu, and stating that the situation was still "critical". A day later, medical experts disagreed with Lee's data and estimated COVID-19's fatality rate at 0.098%, lower than the 0.1% recorded for the flu. Dr. Joseph Tsang Kay-yan also mentioned that the death rate of 0.098% could be even lower in reality, due to citizens not reporting their infections, plus an accounting difference, where people who die with COVID-19 are counted as a COVID-19 death, even if the underlying cause of death was not due to COVID-19. In September 2022, the Hong Kong Association of Athletics Affiliates, organizer of the Standard Chartered Hong Kong Marathon 2022 issued an ultimatum to the government, stating that they would have to cancel the marathon if there were no government approval by 16 September 2022. The date passed without government approval and the event was cancelled; Lee later said "we feel disappointed that the organizer made the decision before the government's reply." On 20 September 2022, Huang Liuquan, an official at the Hong Kong and Macau Affairs Office, made a speech which
