To the Editor—To date, there are no reported outbreaks of coronavirus disease 2019 (COVID-19) among traditional Chinese medicine (TCM) practitioners and their patients. Traditional Chinese medicine is popular globally, especially in Asian populations such as in Hong Kong. The concept of integrative medicine is appreciated by members of the public.1 2 Patients who do not want to be treated by Western medicine often seek TCM herbal remedies instead. Practitioners of TCM are confronted with infection control issues when they treat patients with mild and vague symptoms. Some TCM practitioners wear personal protective equipment, including mask and gown, to protect themselves during consultations. However, several routine TCM manoeuvres are high-risk. In TCM, the tongue is considered to have many relationships and connections in the body, both to the meridians and the internal organs. It is therefore considered essential and important to inspect the tongue for confirming TCM diagnoses. Pulse diagnosis also provides TCM practitioners with information about the health of their patients. In terms of treatment, many TCM procedures such as acupuncture, cupping, and moxibustion are considered high-risk. Various issues are encountered by TCM practitioners (Table3 4 5).
There are currently over 10 000 TCM practitioners in Hong Kong, compared with 14 600 doctors of Western medicine. These TCM practitioners have an important role to contribute in sharing the health burden in the current COVID-19 pandemic, at least in diagnosing and treating mild cases. The role of TCM is now well established and the dispensation, storage, and labelling of Chinese herbal medicines has been regulated since 2003. In addition, TCM practitioners are regulated and there are plans for a Chinese Medicine Hospital in Tseung Kwan O.6 Although there is ongoing research into TCM treatment of COVID-19, the role of the discipline is limited and needs deliberation and recognition.3 4 5
In mainland China, the treatment protocol for diagnosis and treatment for novel coronavirus pneumonia has confirmed the integrative role of TCM in the management of COVID-19.7 Treatment is offered based on stages of disease, namely, pre-diagnosis, confirmed (mild, moderate, severe, and critical), and rehabilitation.7 As with many treatment strategies worldwide, trials are ongoing and there has been no current evidence to support or refute many of the novel treatments, neither in Western nor TCM.
The current policy of the Hong Kong SAR government is that all cases are centralised and managed in the public Hospital Authority system, exclusive of private sector or TCM partners. It is recommended that the Hong Kong SAR government may follow the policy in mainland China to provide TCM as a complementary treatment for in-patients with milder disease as part of the healthcare team responding to COVID-19. In addition, TCM can be offered to patients in the pre-diagnosis and rehabilitation periods for health promotion. There is nothing to lose when patients and citizens see that holistic or integrative medicine is provided by the public system. When further evidence of efficacy is established, TCM can be promoted in the other TCM clinics to serve the public.
The TCM practitioners in Hong Kong have important roles in treating patients with suspected COVID-19 in the community.
