Swine Flu

In 2009, the world experienced a new pandemic of swine-origin influenza virus (S-OIV), which initially began in Mexico. We obtained an administrative supplement from NIDA to study the following aims:

  1. To establish a rapid surveillance protocol for monitoring the incidence of S-OIV among injection drug users (IDUs) and female sex workers (FSWs) participating in our ongoing NIDA-funded studies and other members of these marginalized communities in Tijuana and Ciudad Juarez.
  2. To determine clinical attack rates (i.e. incidence rates) and mortality rates in confirmed S-OIV cases among IDUs and FSWs in Tijuana and Ciudad Juarez.
  3. To characterize risk factors for S-OIV infection, such as poor living conditions, exposure to known/suspected cases, mobility within Mexico, cross-border mobility, prevalence of TB and HIV, and barriers to health care utilization and antiviral treatment adherence.
  4. To assist public health officials in Mexico, the US and internationally in the detection, characterization, and treatment of S-OIV cases among disenfranchised IDU and FSW populations in Tijuana and Ciudad Juarez.

This study is a rapid-response monitoring and mitigation project that is being conducted in collaboration with well-established local and state public health partners in Mexico, as well as the Border Infectious Disease Surveillance team from San Diego, California and the Divisions of Global Public Health and Infectious Disease at UCSD.
