Lo Chung-mau (Chinese: 盧寵茂, born 7 August 1961) is a specialist in liver transplant and is currently the Secretary of Health of the Government of Hong Kong.

[12] On 13 August 2022, Lo admitted that the previously-mandated seven days of hotel quarantine had failed to meet the government's expectations and came at a high cost.

[20] On 12 September 2022, SCMP reported that the government's Covid-19 Expert Advisory Panel, composed of six medical specialists, had several members who suggested gradually lifting COVID-19 restrictions (including removing hotel quarantine by November 2022), with Lo and Ko Wing-man expressing their doubts about their suggestions and preferring a cautious approach.

"[22] 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.

[22] On 15 September 2022, Lo supported Lee's assertion that COVID-19 was 6 times more deadly than the flu, and accused the experts of misleading the public and using faulty reasoning.

[24] On 25 September 2022, Lo said that the "0+0" policy of no quarantine and no self monitoring was not appropriate for the city, and said the reason was that people flying in were 3x more likely to be infected than local residents.

[27][7] On 29 September 2022, Lo emphasized that Hong Kong's anti-epidemic policy was based on the dominant need to protect mainland China, stating "This is our obligation: to make sure that we won't cause a major outbreak in the rest of China," and that the city could not follow other countries in anti-epidemic measures, saying "I don't think Hong Kong can just look at the international thing and follow the rest of the world.

"[28] On 5 October 2022, legislative council member Doreen Kong criticized the government and Lo for invalidating 20,000 COVID-19 vaccine exemption passes, stating that he had no legal authority to do so, with Koon asking "Who is destroying the rule of law now?

"[29][30] On 7 October 2022, Kwok Cheuk-kin filed a judicial review to the High Court, challenging Lo's decision to invalidate the vaccine exemption passes.

[33] After losing the case, the government set to change the law to give them the legal authority to invalidate the vaccine exemption passes.

[36] On 6 October 2022, the Trail Runners Association of Hong Kong requested an urgent meeting with Lo, asking why trail running was subject to stricter restrictions than other activities, saying current policies had "inconsistent, illogical, unfair restrictions" and "This undermines the credibility of Hong Kong's decision-making process on these issues, not only locally, but also globally.

"[46] Two days later on 13 December 2022, it was announced that LeaveHomeSafe QR codes could be removed from venues and people will no longer have to check in with the app.

[48] On 29 December 2022, Lo said that the government's move to drop the vaccine pass and other restrictions were not sudden, but planned, and that the healthcare system was now capable of handling outbreaks of Covid.

[56] In February 2023, Lo agreed that there should be no independent investigation into the government's handling of the pandemic, and said "We have constantly reviewed, improved and adjusted our policies, just like what other countries have done.

[59] In August 2022, Lo held a meeting to discuss Chinese leader and CCP general secretary Xi Jinping's "important speech" given on 1 July 2022, stating "Xi Jinping's important speech reflects in full his care, attention and support for the Hong Kong SAR as well as the country's staunch and firm commitment to the full and faithful implementation of the principle of "one country, two systems".

"[60] Lo also asked coworkers in the Department of Health to "grasp the core essence of Xi's speech and build it into their own work".

"[62] On 29 October 2022, Lo said that the government may implement a minimum period of time in which healthcare professionals must work at a public hospital before they can leave.

[66] Lawmaker Shiu Ka-fai criticized the decision, saying that government was already planning minors' lives, that it would reduce freedom of choice, and potentially stop talent from coming to Hong Kong.

"[69] In September 2023, Henry Fan said of the plan "Regrettably, we have not been able to hire people with high professional achievements, as they have already established their careers overseas.
