TUNIS, June 22 (Xinhua) -- Tunisia risked a new wave of COVID-19 infections as the positivity rate has risen to 21.75 percent over the past week from about 7 percent at the beginning of June, the Tunis Afrique Presse (TAP) reported on Wednesday.

       "The rebound of infections is mainly due to waning vaccine protection after four months of people's injections as well as their reluctance to receive the third and fourth boosters," TAP quoted Riadh Daghfous, a member of the Tunisian scientific committee for the fight against the coronavirus, as saying.

       From June 13 to 19, Tunisian Health Ministry reported 2,277 new COVID-19 cases, raising the total tally of infections in the North African country to 1,046,703.

       Meanwhile, the death toll from the virus rose by 14 to 28,670 in the country.

       Since the start of the national vaccination campaign on March 13, 2021, a total of 6,376,006 Tunisians have been fully vaccinated against the virus.
