ALL 14 regions of the country will on Monday migrate to stage 3 of the lockdown exit strategy for the next 28 days - except for Walvis Bay, which will go back to stage 1 until 8 June.
Case number 21 is a truck driver (43) who had allegedly contravened quarantine regulations and visited various businesses.
Health minister Kalumbi Shangula said Walvis Bay is a major destination for travellers from high-risk countries.
He said stage 1 regulations will include the closure of schools and higher education institutions, the prohibition of public gatherings of more than 10 people, the banning of travelling without a permit as well as the sale of alcohol, and the restriction of movement.
Shangula said stage 3 involves the relaxation of some regulations, such as gatherings of not more than 50 people being allowed.
