1. National Regulations on Epidemic Prevention and Control

China's epidemic prevention and control system is governed by several national laws and regulations. Key policies include:

a. Infectious Disease Prevention and Control Law (传染病防治法)

• This law categorizes infectious diseases into three classes (Class A, B, and C) based on their severity and transmissibility.
• Class A diseases (e.g., plague, cholera) require the strictest control measures, including quarantine and isolation.
• Class B diseases (e.g., COVID-19, SARS, tuberculosis) require reporting, monitoring, and targeted control measures.
• Class C diseases (e.g., influenza, mumps) require basic prevention and control measures.

b. Emergency Response Law (突发事件应对法)

• This law outlines the government's responsibilities during public health emergencies, including epidemic outbreaks.
• It mandates the establishment of emergency response plans at national, provincial, and local levels.

c. Health QR Code System

• Introduced during the COVID-19 pandemic, the health QR code system (健康码) is a digital tool used to track individuals' health status and travel history.
• It is integrated into apps like Alipay and WeChat and is often required for entry into public spaces, transportation, and workplaces.

d. Vaccination Regulations

• Vaccination is a key component of epidemic prevention. China has a National Immunization Program (NIP) that provides free vaccines for certain diseases.
• Additional vaccines, such as those for COVID-19, may be offered for free or at a subsidized cost during outbreaks.

2. Standard Procedures for Epidemic Prevention and Control

China has a well-defined set of procedures for managing epidemics. These include:

a. Entry and Exit Requirements

• Health Declaration Form: All international travelers must complete a health declaration form before entering China. This can be done online or via a paper form at customs.
• Quarantine Measures: Depending on the current epidemic situation, travelers may be required to undergo health screenings, nucleic acid tests (NATs), or quarantine upon arrival.
• Vaccination Records: Proof of vaccination (e.g., for COVID-19) may be required for entry during certain periods.

b. Testing and Reporting

• Nucleic Acid Testing (NAT): NATs are widely used to detect infectious diseases like COVID-19. Testing is available at hospitals, clinics, and designated testing centers.
• Reporting Symptoms: Individuals experiencing symptoms of infectious diseases are required to report to local health authorities or visit a hospital immediately.

c. Isolation and Quarantine

• Home Quarantine: For mild cases or close contacts, home quarantine may be mandated.
• Centralized Quarantine: In more severe cases or for international arrivals, individuals may be required to stay in government-designated facilities.

d. Public Health Measures

• Mask Mandates: During outbreaks, wearing masks in public spaces is often mandatory.
• Temperature Checks: Temperature screening is common at airports, train stations, and public venues.
• Disinfection: Public spaces, transportation, and facilities are regularly disinfected during epidemics.

e. Vaccination Campaigns

• During outbreaks, mass vaccination campaigns are organized. Vaccines are administered at hospitals, community health centers, and temporary vaccination sites.

3. Associated Costs

The costs of epidemic prevention and control measures in China vary depending on the service and the individual’s circumstances:

a. Testing Costs

• Nucleic Acid Tests (NATs): The cost of a NAT ranges from 16 to 50 RMB (approximately $2–$7 USD), depending on the location and provider. Some local governments may offer free testing during outbreaks.
• Antigen Tests: Rapid antigen test kits are available for purchase at pharmacies for around 5–20 RMB ($0.70–$3 USD) per kit.

b. Quarantine Costs

• Centralized Quarantine: Costs for government-designated quarantine facilities (e.g., hotels) are typically borne by the individual. Prices range from 200 to 600 RMB ($30–$85 USD) per day, including meals.
• Home Quarantine: Generally free, but individuals are responsible for their own living expenses.

c. Vaccination Costs

• Vaccines under the National Immunization Program are free for residents, including some immigrants with valid residency permits.
• Non-NIP vaccines (e.g., certain travel vaccines) may cost between 100 and 600 RMB ($15–$85 USD) per dose.

d. Medical Treatment

• Treatment for infectious diseases in public hospitals is subsidized, but costs vary based on the severity of the illness and the individual’s insurance coverage.
• Foreigners are advised to have health insurance that covers infectious diseases.

4. Country-Specific Considerations

Visitors and immigrants should be aware of the following unique aspects of China’s epidemic prevention and control system:

a. Health QR Code System

• The health QR code is a critical tool for daily life during epidemics. Ensure you have a smartphone with access to Alipay or WeChat to generate and display your code.
• Green code: Normal health status; Yellow or Red code: Restrictions on movement and mandatory testing or quarantine.

b. Community-Based Management

• Local communities (社区) play a significant role in epidemic prevention. Community workers may conduct health checks, distribute supplies, and enforce quarantine measures.
• Visitors and immigrants should register with their local community office upon arrival.

c. Language Barriers

• Most epidemic-related information is provided in Chinese. It is advisable to use translation apps or seek assistance from bilingual individuals.

d. Cultural Norms

• Compliance with public health measures is highly emphasized in China. Wearing masks, following quarantine rules, and cooperating with health authorities are expected behaviors.

e. Travel Restrictions

• During outbreaks, domestic travel may be restricted. Check local regulations before planning trips within China.

5. Tips for Visitors and Immigrants

• Stay Informed: Follow updates from the National Health Commission (NHC) and local health authorities.
• Carry Essentials: Keep masks, hand sanitizer, and your health QR code accessible at all times.
• Purchase Insurance: Ensure your health insurance covers epidemic-related costs, including testing, treatment, and quarantine.
• Follow Local Rules: Regulations may vary by city or province, so always check local guidelines.
