Dear colleagues and students,

As Macau has entered the peak flu season, we would like to remind everyone to take personal protective measures. Please refer to Health Bureau’s infographics on “Wearing Masks to Prevent the Spread of Respiratory Diseases” to reduce the risk of transmission and infection below for your information.

Wearing Masks to Prevent the Spread of Respiratory Diseases

Why wear a mask when you have the flu, COVID-19, or other respiratory infectious diseases?

1. When you’re sick, your immune system is weakened. Wearing a mask helps prevent co-infection with other respiratory diseases, which could worsen or prolong your illness.
2. Wearing a mask helps reduce the spread of viruses to your family and friends.

When Should You Wear a Mask?

1. When experiencing flu-like symptoms such as fever, muscle aches, sore throat, cough, or runny nose.
2. When testing positive for respiratory viruses such as COVID-19.
3. When entering healthcare facilities, elderly care homes, or rehabilitation centers.
4. When there is a cluster of infections in workplaces, daycare centers, or non-tertiary educational institutions.

* In other situations, you may decide whether to wear a mask based on your personal health condition and risk.

Should You Wear a Mask When Travelling by Plane, Bus, or Other Public Transport?

Since it is usually crowded on public transport with many passengers, facilitating the spread of respiratory diseases:

1. It is recommended that individuals aged 3 and above wear a mask to protect themselves, especially during peak flu seasons.
2. If you experience flu-like symptoms such as fever, muscle aches, sore throat, cough, or runny nose, you should wear a mask to prevent spreading diseases.

Thank you for your attention.
