One, what are the criteria for determining close contacts?
Suspected cases and confirmed cases of symptoms began 2 days before the emergence of symptoms, or asymptomatic infected specimens sampling began 2 days before the start, with their close contact but did not take effective protection of the personnel. Epidemiological investigation professionals based on the results of epidemiological investigations, combined with the information provided by the relevant departments of the big data, based on the following principles to determine close contacts:
1. family members living in the same room *** together;
2. direct caregivers or provide diagnosis and treatment, nursing services;
3. implementation of the aerosol may produce diagnostic and therapeutic activities in the same space Health care workers;
4. In offices, workshops, shifts, elevators, cafeterias, classrooms, and other places with close contact with all the personnel;
5. Confined environment *** meal, *** with entertainment, as well as the provision of catering and recreational services;
6. Visiting cases of health care workers, family members, or other persons with close contact;
7. People who traveled on the same mode of transportation and had close contact, including caregivers and companions on the transportation;
8. People who were exposed to the environment and objects contaminated by the case or asymptomatic infected person;
9. People who were assessed by the on-site investigators as meeting the criteria for close contacts.
Two, what is close contact of close contact?
Closely contacted with the case 2 days before the onset of disease or asymptomatic infected specimens sampled 2 days before to be isolated before the management of the period of time from the beginning of the first contact to the close contacts were isolated before the management of the close contacts, and close contacts with the close contacts have *** with the living life, the same confined environment for work, gatherings and recreation, such as proximity contact, but did not take effective protection of the personnel.
Three, what is the general contact?
With suspected cases, confirmed cases and asymptomatic infected persons in the same transportation such as airplanes, trains and ships, *** with the same life, study, work and diagnosis and treatment process has been in contact with, as well as *** with the same exposure to shopping malls, farmers' markets, bus stops, subway, and other public **** place of personnel, but not in line with the principle of close contact determination of the person.
Four, if you receive notification from the CDC that you are a close contact/closely connected close contact, what should I do?
No need to panic, do not go out casually, do a good job of personal protection, in accordance with the requirements of the centralized isolation for medical observation, and actively cooperate with the isolation and control measures and the CDC department of the flow of work. For children aged 14 years and below, semi-autonomous and non-autonomous special groups can be taken home medical observation, and the strict implementation of home medical observation measures. Temperature and symptoms should be monitored daily during the period of isolation for medical observation. If fever, cough, sore throat, loss of smell and other symptoms should be promptly investigated, diagnosis and treatment.
V. How long does it take to keep close contacts/closely connected people under close isolation medical observation?
Based on the incubation period of the disease caused by the new coronavirus, the period of centralized isolation observation of close contacts is 14 days from the last contact with the case, asymptomatic infected persons without effective protection, and it is recommended that after the expiration of the quarantine period and then conduct home health monitoring of close contacts for 7 days to avoid the spread of a very small number of cases of excessively long incubation period. The duration of medical observation of close contacts in close centralized isolation is determined according to the nucleic acid test results of close contacts.
Six, worried about and confirmed, suspected patients with public **** transportation how to do?
Using the national government service platform and the National Health Commission to launch the "peer close contact self-check service", you can safely and quickly query their own whether the patient peer close contact. If the query is a close contact, you do not have to worry too much, fill out the page appeared on the "self-declaration", strengthen self-check, protection and isolation observation, to help do a good job in the prevention and control of new coronavirus pneumonia.
