Close Contact with COVID-19 Cases in Singapore: A Comprehensive Guide to Understanding, Managing, and Mitigating Risks

As the COVID-19 pandemic continues to evolve, understanding and managing close contact with infected individuals remains crucial in preventing its spread. Singapore, known for its robust healthcare system and effective public health measures, has established clear guidelines and protocols to address close contact situations. This article provides a comprehensive guide to close contact with COVID-19 cases in Singapore, covering its definition, testing protocols, isolation requirements, and risk mitigation strategies.

Definition of Close Contact

According to the Singapore Ministry of Health (MOH), a close contact is defined as an individual who has been in close proximity with a confirmed or probable COVID-19 case for an extended period. Specifically, this includes:

• Spending more than 15 minutes within 2 meters of an infected person
• Coming into direct physical contact with an infected person (e.g., touching or hugging)
• Having face-to-face interactions with an infected person for more than 30 minutes without wearing a mask
• Traveling in the same vehicle with an infected person for more than 30 minutes (excluding taxi or ride-hailing services)

Testing Protocols for Close Contacts

When an individual is identified as a close contact, they are immediately advised to undergo COVID-19 testing. The testing protocols vary depending on the individual's vaccination status and exposure circumstances.

Vaccinated Individuals:

• As of May 23, 2022, fully vaccinated asymptomatic close contacts of COVID-19 cases are generally not required to undergo testing unless they are deemed to be at higher risk of severe disease (e.g., elderly, immunocompromised).
• If symptoms develop, individuals should self-isolate and get tested immediately.

Unvaccinated or Partially Vaccinated Individuals:

• Unvaccinated or partially vaccinated close contacts are required to undergo a polymerase chain reaction (PCR) test within 24 hours of exposure.
• Additional testing may be required based on individual circumstances.

Isolation Requirements for Close Contacts

Close contacts of confirmed or probable COVID-19 cases are required to isolate for a specific period to prevent further transmission. The isolation period depends on the individual's vaccination status and exposure circumstances.

Vaccinated Individuals:

• Vaccinated close contacts who are asymptomatic are required to isolate for 5 days.
• During this period, they should stay home and avoid contact with others.

Unvaccinated or Partially Vaccinated Individuals:

• Unvaccinated or partially vaccinated close contacts who are asymptomatic are required to isolate for 10 days.
• If symptoms develop during the isolation period, individuals should immediately contact their healthcare provider.

Risk Mitigation Strategies

In addition to testing and isolation requirements, close contacts should implement risk mitigation strategies to minimize the spread of COVID-19. These strategies include:

• Wearing a mask in public places and crowded settings
• Avoiding close contact with others (maintaining a distance of at least 2 meters)
• Practicing good hand hygiene (washing hands regularly with soap and water or using hand sanitizer)
• Monitoring for symptoms of COVID-19 (e.g., fever, cough, shortness of breath) and getting tested immediately if symptoms appear
• Getting vaccinated and boosted when eligible

Common Mistakes to Avoid

To effectively manage close contact with COVID-19 cases, it is important to avoid common mistakes that can increase the risk of transmission. These mistakes include:

• Ignoring the isolation requirements
• Failing to wear a mask in public places
• Neglecting proper hand hygiene
• Not getting tested if symptoms develop
• Failing to cooperate with public health authorities

Step-by-Step Approach for Close Contacts

Following a step-by-step approach can help close contacts navigate the process effectively. This approach includes:

Step 1: Get Tested

• Undergo COVID-19 testing within 24 hours of exposure, as per the recommended protocols.

Step 2: Isolate

• Isolate for the required period (5 days for vaccinated asymptomatic individuals; 10 days for unvaccinated or partially vaccinated asymptomatic individuals) to prevent further transmission.

Step 3: Monitor for Symptoms

• Monitor closely for symptoms of COVID-19, such as fever, cough, and shortness of breath.

Step 4: Seek Medical Advice if Symptoms Appear

• If symptoms develop during isolation, contact a healthcare provider immediately and get tested.

Step 5: Cooperate with Public Health Authorities

• Cooperate with public health authorities, such as the Ministry of Health, and provide accurate information about your exposure and contacts.
