People who live, study, work together or have close contact with a case, such as face-to-face working, sharing the same classroom or living in the same household;2. Medical staff who provide direct care, family members or others who have similar close contact with case, such as visiting or staying at the same hospital ward;3. People who have close contact with the case on the same public?transportation, including the caregivers, other passengers and crew members whose peers (family, colleagues, friends, etc.) have been found to have close contact with the case after investigation and evaluation. See Guidance for identification of close contacts on different public transportations for further information specific to identify close contacts on different public transportations.4. People who are evaluated as meeting other close contact definitions by the field investigators.Guidance for identification of close contacts on different public transportations1. Aircraft1.1 Generally, all passengers sitting in the same row and three seats in any direction of the case, crew members serving in the section where the case was seated are regarded as close contacts. Other passengers on the same flight are considered general contacts.1.2 All persons in the cabin of an aircraft not equipped with a high-efficiency particulate filter on.1.3 Others have close contact with the case.2. Railway and train2.1 All the passengers and crew members in the same hard seat or hard sleeper carriage, in the same soft sleeper compartment with the case in the fully enclosed, air-conditioned train.2.2 Passengers and the crew members in the same soft sleeper compartment, or in the same hard seat (hard sleeper) in the same or neighboring grid of the case carriage with the case in the partly enclosed train.2.3 Others have close contact with the case.3. Automobile3.1 All passengers included, when take the same fully sealed, air-conditioned bus with the cases.3.2 The passengers and drivers with three rows of seats in the front and rear of the case in a well-ventilated passenger car.3.3 Others have close contact with the case.4. ShipAll the passengers and crew members in the same cabin with the case.Contacting with the case who showed symptoms such as high fever, sneezing, coughing or vomiting regardless of time.Appendix 2: COVID-19 Confirmed Case Investigation FormQuestionnaire number: Identity number: Basic InformationName: (Please fill in guardian’s name if the case was a child)Gender: □Male □FemaleDate of birth: / / (D, M, Yr.), age: (If the date of birth is unclear, the chronological age is Years Months)Place where the case was diagnosed: Province Prefecture District/County Township/Street Village/CommunityTelephone: Date of Initial Symptom Onset: / / (D, M, Yr.)Date of laboratory confirmation test: / / (D, M, Yr.)Types of case definitions: □Suspected case □Confirmed case □Positive test caseClinical severity: □Asymptomatic infection □Mild cases□General pneumonia □Severe pneumonia □Critical pneumoniaOnset and Hospitalization InformationClinical Signs and Symptoms:□Fever: If yes, highest temperature is ℃□Chill □Cough □Sputum production □Nasal congestion □Rhinorrhea □Sore throat □Headache □Fatigue □Myalgia □Arthralgia □Shortness of breath □Difficulty breathing □Chest tightness □Chest pain □Conjunctival congestion □Nausea □Vomit □Diarrhea □Stomach ache □Others: Complications: □No□YesIf yes, tick an answer (multiple-choice): □Meningitis □Encephalitis □Bacteremia/Sepsis □Myocarditis □Acute lung injury/ARDS □Acute kidney injury □Epilepsy □Secondary bacillary pneumonia □Others: Did the case take an blood routine examination: □No □YesIf yes, date of test: / / (D, M, Yr.)
