Swine flu is suspected in at least 149 deaths and 1,995 cases, with nearly all states reporting infections. Officials look at what is thought to be the first case, near a pig farm in Veracruz. With the death toll climbing, Mexican authorities at the center of an international swine flu epidemic struggled Monday to piece together its lethal march, with attention focusing on a 4-year-old boy and a pig farm.
