1. Apply for health code for the first time or reapply. If the health code is black, it means that the health code applied by the user is under review. When the review is completed, the green code, yellow code and red team will be displayed.
2. The mobile phone has no network data, resulting in the health code image not being refreshed, and the background color of the health code is black. At this point, you can open the network data and click the refresh button to try to change it to the normal color of the health code.
3. If the user fails to authenticate or verify the health code after application, the health code will be displayed in black and needs to be re-verified, and the color of the health code will not be displayed until it is approved.
4. If the health code is displayed in black for a long time after taking the above measures, you can contact the customer service hotline on the health code page to explain the situation and solve it through transcoding.
2 Do you want to isolate the health code black? No need for isolation.
At present, the people who need to be isolated during the epidemic are:
1, COVID-19 cases and asymptomatic infected persons must be concentrated in medical institutions for isolation treatment.
2. Close contacts between patients and asymptomatic infected persons, as well as close contacts, need to be isolated at centralized isolation points.
3. People designated as medium-risk areas need to be isolated at home.
Black health code is neither an infected person in COVID-19 nor an early warning of medium risk, so there is no need for isolation. However, it should be noted that the black health code cannot go to public places, because it is necessary to show the green health code when entering and leaving public places during the epidemic.
3 health code black can be used as nucleic acid? No nucleic acid.
When doing nucleic acid testing, it is required to provide a green health code. If it is black, it cannot be tested. If it is yellow, it is necessary to go to the place designated by the yellow code for nucleic acid testing, while the red code will be tested by a special person. Therefore, the black health code personnel should turn to the green code as soon as possible before they can go to the nucleic acid point sampling and nucleic acid detection.
4 Can health code black be vaccinated? number
When you go to the hospital for vaccination, whether it is COVID-19 vaccine or other vaccines, you need to show the green information of health code, but you are not allowed to enter the black health code, so you can't vaccinate with the black health code.
At the same time, all vaccines in COVID-19 are registered in real-name registration system, and you need to carry your ID card for identity authentication. After residents are vaccinated with COVID-19 vaccine, the staff will directly print the vaccine-related information on the vaccination record page, including vaccine name, manufacturer, vaccine batch number, expiration date, vaccination location, vaccination date, vaccination location or display it on the mobile phone health code page.
