The Zika outbreak in Brazil hasn't dampened Chinese enthusiasm for the 2016 Summer Olympic Games in the South American country, according to an authorized ticket reseller in China.

Since tickets for the Rio Games went on sale in China on January 19, nearly 1,000 tickets have been booked, and tickets for events where Chinese athletes are favored sell best, such as gymnastics, diving, table tennis and badminton, Chinese tour operator Caissa Touristic told the Global Times on Sunday.

"Although the Chinese economy has slowed down, preparation for the Rio Games has drawn criticism, and the Zika virus has spread in Brazil, Chinese continue to show great interest in going to the Games," Caissa replied in an e-mail.

However, some people said the Zika virus would have an impact. A 20-year-old college student from Zhuzhou, Hunan Province said she remains undecided. She applied as a volunteer at the Rio Games in August 2014, and in December 2015 was informed she was ­accepted. "But since the Zika ­virus broke out in Brazil, my parents advised me not to go," she said. "I am also worried about Zika."

But to others, the cost of going to Brazil, instead of Zika, is the obstacle. "Zika is a small problem compared to the trip's cost," a fan surnamed Zhang in Tianjin told the Global Times, adding that the cost would equal his annual income.

Caissa have also launched tour packages, such as 10-day trips to Brazil, including ­tickets to the table tennis final, which costs about 60,000 yuan ($9,170).

"Inquiries about tickets and packages are increasing," said Caissa, which helps provide ticketing and hospitality services for the Games.

Caissa said the tickets most in demand by the Chinese are those for the opening ­ceremony, men's swimming, women's volleyball, diving and badminton.

In an effort to attract Chinese spectators, Brazilian President Dilma Rousseff on Friday opened an account on Sina ­Weibo, a Chinese microblogging website.

In a 96-second video, she invited Chinese to visit Brazil during the Olympic Games (August 5-21) and Paralympic Games (September 7-18).

Official figures show 7.5 million tickets are available for the Rio Olympic Games, 70 percent of which have been earmarked for Brazil residents. Non-residents can only buy tickets at agents in their home country or region.

The first round of ticket sales in China will end on March 31, with the next round yet to be decided, Caissa said. Tickets to the opening and closing ceremonies remain unavailable in China.
