Why is TB male-baised?
Is it an excess of cases among men because they have greater access to
health care than women?
Do men have more frequent opportunities for exposure?
In most countries, men smoke more cigarettes than women leading to
toxic lung injury and reduced immune cell function leaving them more
susceptible to infection.
Alcohol use is also identified as a risk factor for TB disease as it may
have immunosuppressive effects.
Social roles men fill and social roles influence mixing with others in
rel = relapse
sn = negative
sp = positive

What happened around 1995?
By October 31, 500,000 cases of AIDS have been reported in the US.
How many in the world?
Was there a TB awareness drive?
The reason for less cases in USA + declining cases could be good health care system and health infrastructure.
The reason of spread of TB in developing countries could be increase in pollution because a lot of goods are manufactured in India, China etc. and the working conditions are poor for example low ventilation, long working hours, poverty, malnutrition and weak health infrastructure.
