NEW DELHI, Oct. 23 (Xinhua) -- The number of Zika virus outbreak cases has reached 120 in western Indian state of Rajasthan, with more people been diagnosed with the infection over the past 48 hours, the state's health chief has said.

"Till now, 120 people have been tested positive for Zika virus in the state, 105 of them have been treated," Rajasthan's Health Minister Kalicharan Saraf told the media here on Monday evening.

The Indian Health Ministry has already sent a special team to the state and set up a control room at National Centre for Disease Control to undertake regular monitoring of the situation in Rajasthan and take necessary measures.

Zika virus disease is spread by daytime-active Aedes mosquitoes. Its symptoms include fever, skin rashes, conjunctivitis, muscle and joint pain, and headache.

This is the third Zika virus outbreak in India since January 2017.

The first outbreak of Zika was reported in India in January 2017 in western state of Gujarat, while the second outbreak was reported in the southern state of Tamil Nadu in July 2017. Both outbreaks were contained.
