criticism over efficiency

Unlike China tried to hide seriousness of the SARS virus back in 2003, Mexican government responded to the emergence of the swine flu virus promptly and efficiently to keep virus under control. They quarantined infected and shut down schools, restaurants and other public places where large crowds gather to limit spread of the swine flu virus. Through news, I have seen the Mexican government even distributed breathing masks to curtail the disease’s spread.
However, the Mexican government also received criticism for taking long times (7-8 weeks) for the dead from the swine flu virus to seek medical attention to receive earlier treatment and prevent further victims. Also Mexicans depends on outside resources to diagnose/identify the strain of virus domestically.
As the swine flu virus has unfolded, the Mexican health system has come under increasing pressure. I believe Mexico has universal health insurance but they at same time face overcrowded and understaffed clinics and hospitals. Mexicans have everything from a small, private system to huge universal health insurance programs that mix private, public and employer funding. Despite the array of services, it's a more likely to be an unequal system because of limited resources (Health care professionals and equipments) and lack of infrastructure/management within the system. Mexico is one of the countries who spends the least % of their GDP on health care budget. but it is surprising to me that even Mexico has universal health care which US doesn’t have.
