Media reports up to 54 people have been hospitalized in an outbreak of acute watery diarrhoea (AWD) in Mekelle city, 783 km (about 486 miles) north of Addis Ababa. Local health officials say the outbreak is linked to poor food and personal hygiene practices.
Prevention depends mainly upon practising good hand hygiene and effective food and water precautions.
Diarrhoea may occur even in travellers who stick strictly to food and water precautions in many destinations the risk is determined by local food hygiene and sanitation practices.
In certain circumstances prophylactic medication or vaccination may be considered, see chemoprophylaxis.
