TUNIS, Jan. 10 (Xinhua) -- A senior Tunisian health official on Sunday warned of the exponential spread of the COVID-19 in Tunisia, saying the pandemic has reached Stage Four, Tunis Afrique Presse (TAP) reported.
"During this stage, contracting COVID-19 within a family exposes all members to the risk of infection, which is likely to worsen the number of cases across the country," said Chokri Hammouda, director general of National Authority for Assessment and Accreditation in Healthcare, in a statement quoted by TAP.
The COVID-19 vaccine actually offers individual but not collective protection, Hammouda noted.
He also warned people who have recovered from coronavirus not to ignore prevention measures, saying they could be infected again.
Given the critical situation in Tunisia, "it is imperative to put in place an integrated plan to fight the spread of the virus and to conduct a vaccination campaign," Hammouda said.
"Anyone showing symptoms of a seasonal flu is called upon to behave as a person with COVID-19," he added.
Tunisia reported 2,611 new COVID-19 cases on Saturday, raising the total number in the North African country to 157,514, including 5,153 deaths.
