Personal & Environmental Hygiene
A. Personal hygiene
1. Keep hands clean, wash hands frequently with liquid soap and water, especially before touching the mouth, nose, or eyes, before handling food or eating, and after going to toilet, touching public installations or equipment such as escalator handrails, elevator control panels or door knobs, or when hands are dirtied by respiratory secretion after coughing or sneezing.
2. Cover the mouth and/or nose with tissue paper when coughing or sneezing. Dispose of the soiled tissues properly into a lidded rubbish bin, and then wash hands thoroughly.
3. Wear a mask if developing fever or respiratory symptoms, going to a hospital or clinic, or if caring for a patient with fever or respiratory symptoms.
4. If flu-like symptoms develop, stay at home and avoid going to crowded or poorly ventilated places.
5. Build up good body immunity by having a balanced diet, regular exercise and adequate rest, do not smoke and avoid alcohol consumption.
