Argentine President Cristina Kirchner confirmed on her Twitter account Wednesday that she has resumed official duties after 20 days of medical leave for surgery on her thyroid.
"Today (Wednesday) we resume activities. Beginning at 7 pm, at Government House, we will sign agreements for public works with the provinces ...", says the president's message.
It was her first message since January 7, when she thanked supporters for concern over her health problem.
The president, 58, underwent surgery to remove her thyroid gland after a cancer diagnosis, which later tissue analysis tests showed was an inaccurate diagnosis.
Kirchner plans to attend a ceremony at the Casa Rosada government headquarters to sign agreements for public works projects valued at ê275 million and hold videoconferences with several districts.
After spending most of her convalescence at her official residence in Olivos in the northern suburbs of Buenos Aires, she spent last weekend with her children, Max and Florencia, at their summer home in the resort of
Chapadmalal, 430 kilometers (267 miles) south of the capital.
The president underwent surgery less than a month after her inauguration on December 10. She won reelection to a second term during the October election with 54.11% of the vote.
During her medical leave, Vice President Amado Boudou officially assumed her executive duties.
Kirchner is Argentina's first elected female president. She succeeded her husband, Nestor Kirchner, who died of a heart attack in October 2010.
