(CNN) -- Venezuelan President Hugo Chavez was gradually recovering and handling more presidential duties, a government official said Tuesday.
"He's constantly thinking, making decisions, in meetings he's been giving out orders," the Minister of Science, Technology and Innovation Jorge Arreaza, said on Venezuela state TV.
Chavez, 58, has not made a public appearance since undergoing a fourth cancer surgery in Havana more than a month ago..
The government has not released any photographs of the ailing leader, and Chavez hasn't spoken on state television.
His long absence from the airwaves is not typical. And his lengthy stay in Cuba has sparked growing concerns from political opponents about who is running Venezuela while he's gone.
Arreaza's statement follows a chorus of other government officials who have made announcements recently about the improving state of the longtime president's health.
Last week Information Minister Ernesto Villegas stressed that Chavez was still very much in charge of the country, meeting with leaders and making key decisions.
That same sentiment was expressed the same day by Vice President Nicolas Maduro, who recently returned from visiting Chavez in Cuba.
"(He) is in the best moment that we've seen him in all these days of struggle," Maduro said.
