As a precautionary measure the government has banned gatherings of more than 50 people and the entry of people from countries deemed high-risk.[2][3] On March 24, the government announced that borders would be closed. Citizens of Botswana are permitted to return but must be quarantined for 14 days. There is concern, however, that people may still enter Botswana illegally from Zimbabwe by avoiding official border crossings.[4]
