LIMA, Feb 26 (Reuters) - Peru declared a health emergency across most of the country on Monday as a heat wave and heavy rains have led to a spike in dengue fever cases.
The South American nation's death toll due to the virus has risen to 32 so far this year, Health Minister Cesar Vasquez said on Monday.
Total cases also climbed to 31,300 in the first eight weeks of the year, Vasquez said, up from 24,981 in the first seven weeks.
