The Mexican government closed most of Mexico City's public and private facilities in an attempt to contain the spread of the virus; however,it continued to spread globally,and clinics in some areas were overwhelmed by infected people. The new virus was first isolated in late April by American and Canadian laboratories from samples taken from people with flu in Mexico, Southern California and Texas. Soon the earliest known human case was traced to a case from 9 March in a 5-year-old boy in La Gloria, Mexico, a rural town in Veracruz.In late April the World Health Organization (WHO) declared its first ever "public health emergency of international concern," or PHEIC,and in June, the WHO and the U.S. CDC stopped counting cases and declared the outbreak a pandemic
