Distinguishing and Preventing COVID-19 for Workers in Japan

1. Common Symptoms of COVID-19

COVID-19 can cause a range of symptoms, from mild to severe, which may appear 2 to 14 days after exposure to the virus. Common symptoms include:

• Fever: A prevalent symptom, often with a body temperature above 37.8°C.
• Cough: Usually dry and persistent, which may worsen over time.
• Shortness of Breath: Difficulty breathing or feeling breathless is a significant warning sign, especially when accompanied by chest pain.
• Loss of Taste and Smell: A unique symptom of COVID-19, with reduced or lost ability to taste or smell.
• Fatigue: Prolonged fatigue, muscle weakness, and sometimes body aches.
• Sore Throat and Headache: May feel similar to a cold or flu, with a sore throat and headaches.
• Runny or Congested Nose: Though less common, these symptoms may occur in some cases.
• Nausea, Vomiting, and Diarrhea: These digestive symptoms may appear, especially in children.

2. Distinguishing COVID-19 from Common Flu

During the cold season, it’s easy to confuse COVID-19 symptoms with those of the common flu. While both can cause fever, cough, and fatigue, some differences include:

• Loss of taste and smell is a distinct symptom of COVID-19, rarely seen in the flu.
• COVID-19 often leads to difficulty breathing, which can escalate quickly.
• COVID-19 symptoms tend to last longer than the flu and may cause serious complications like pneumonia and respiratory failure.

3. Causes of COVID-19 Transmission in Japan

Japan, with its dense population and extensive public transportation system, can be a high-risk environment for COVID-19 transmission. Key causes include:

• Close Contact with Infected Individuals: The virus primarily spreads through respiratory droplets from an infected person’s cough, sneeze, or conversation.
• Touching Virus-Contaminated Surfaces: The virus can survive on surfaces, spreading when someone touches the surface and then touches their face.
• Gathering in Crowded Areas: Events, enclosed spaces, and public transport can increase the risk of virus spread.

4. Effective COVID-19 Prevention Measures

To protect yourself and the community, especially for Vietnamese workers in Japan, it’s important to follow strict prevention measures:

• Get Vaccinated: Vaccination is the most effective way to reduce the risk of infection and severe complications. Ensure you receive all recommended vaccine doses.
• Wear a Mask: Always wear a mask when going out or interacting with others, particularly in enclosed spaces or crowded areas.
• Wash Hands Regularly: Use soap and water for at least 20 seconds or hand sanitizer with at least 60% alcohol.
• Maintain Physical Distance: Keep at least 2 meters away from others, especially in high-risk areas.
• Avoid Crowded Places: Refrain from attending events or gatherings unless necessary, and adhere to social distancing regulations.
• Ensure Proper Ventilation: If indoors, ensure good ventilation to reduce the risk of viral transmission.

5. Special Considerations for Vietnamese Workers in Japan

• Regular Health Monitoring: Check your health daily, particularly for respiratory symptoms. Report any signs of illness to your supervisor and seek medical advice if needed.
• Follow Workplace Safety Measures: Adhere to occupational safety regulations, including wearing masks and protective gear.
• Stay in Contact with Family and Health Authorities: In case of illness, keep in touch with family and health authorities for timely support.
• Understand Japan’s Health Regulations: Stay informed about Japanese government regulations and guidelines regarding COVID-19 to ensure compliance.

Conclusion

COVID-19 poses a significant global health threat, and understanding its symptoms, distinguishing it from other illnesses, and following preventive measures is key to protecting yourself and your community. For Vietnamese workers in Japan, taking proactive steps to safeguard your health and adhering to prevention guidelines will reduce the risk of infection and ensure a safe and effective working and living environment.
