RIO DE JANEIRO, Oct. 17 (Xinhua) -- Brazil's Health Ministry on Wednesday confirmed 2,192 cases of measles, of which 12 have died.

Most of the cases occurred in the northern region, in the states of Amazonas and Roraima, with 1776 and 330 cases respectively. In addition to the confirmed cases, 7,894 suspected cases are pending confirmation in these two states.

The health ministry highlighted that a large vaccination campaign is being carried out in the states where cases of measles were registered, with 13.2 million doses of vaccines shipped to those states since the beginning of the year.

Brazil received a measles-free certification from the Pan-American Health Organization (PAHO) a few years ago. If the country does not manage to control the outbreak before February 2019, the certification may be rescinded.
