Could be an asterisk. The asterisk in front of the health code name may be because the first word in the name is not a common word, while the asterisk in the travel code indicates that you have been to the middle-high risk area in the previous 14 days. This asterisk is mainly a travel reminder and does not represent your health.
Health, a Chinese word, means that a person is in good physical, mental and social condition. Health is the basic right of people and the first wealth of life. The traditional concept of health is "disease-free health", while the modern concept of health is overall health. The World Health Organization puts forward that "health is not only the absence of physical diseases, but also mental health, good social adaptation and morality".
