After conducting its investigation, the CDC attributed the source of the outbreak to the use of contaminated raw green onion. The restaurant was purchasing its green onion stock from farms in Mexico at the time. It is believed that the green onions may have been contaminated through the use of contaminated water for crop irrigation, rinsing, or icing or by handling of the vegetables by infected people. Green onion had caused similar outbreaks of hepatitis A in the southern United States prior to this, but not to the same magnitude. The CDC believes that the restaurants use of a large communal bucket for chopped raw green onion allowed non-contaminated plants to be mixed with contaminated ones, increasing the number of vectors of infection and amplifying the outbreak. The restaurant was closed once it was discovered to be the source, and over 9,000 people were given hepatitis A immune globulin because they had either eaten at the restaurant or had been in close contact with someone who had. Special populations
HIV co-infection
Persons infected with HIV have a particularly high burden of HIV-HCV co-infection. In a recent study by the WHO, the likelihood of being infected with hepatitis C virus was six times greater in those who also had HIV. The prevalence of HIV-HCV co-infection worldwide was estimated to be 6.2% representing more than 2.2 million people. Intravenous drug use was an independent risk factor for HCV infection.
Blood pressure is also higher in those with android obesity which leads to cardiovascular disease.Women who are infertile and have polycystic ovary syndrome show high amounts of android fat tissue. In contrast, patients with anorexia nervosa have increased gynoid fat percentage  Women normally have small amounts of androgen, however when the amount is too high they develop male psychological characteristics and male physical characteristics of muscle mass, structure and function and an android adipose tissue distribution. Women who have high amounts of androgen and thus an increase tendency for android fat distribution are in the lowest quintiles of levels of sex-hormone-binding globulin and more are at high risks of ill health associated with android fat High levels of android fat have been associated with obesity  and diseases caused by insulin insensitivity, such as diabetes. Insulin responsiveness is dependent on adipose cell size. The larger the adipose cell size the less sensitive the insulin. Diabetes is more likely to occur in obese women with android fat distribution and hypertrophic fat cells. It is not just general obesity that is a consequence of android fat distribution but also other health consequences. There are connections between high android fat distributions and the severity of diseases such as acute pancreatitis - where the higher the levels of android fat are, the more severe the pancreatitis can be. An increase in android fat distribution is positively correlated with foot pain and disability associated with foot pain.
