HIV/TB
HIV is preventable and TB is curable, but we haven't eradicated either because not everyone can be cured or afford to be cured and because preventing any type of disease is very expensive and is not a simple process. There are many ways to prevent getting HIV like using condoms and avoiding using dirty needles, etc. But HIV can't be eradicated because many people who have HIV don't know they have it until it's too late, and they may or may not have spread it to others. Also, HIV hasn't been eradicated because many of the people who are at risk for HIV don't care about getting the disease. HIV hasn't been eradicated also because TB and HIV are related to each other and they can been found in the same person. For example, in Why does evolution matter today? it explained very precisely the process of evolution which is about how TB and HIV are related to each other and how that relation really affects the person with the disease. It really affects the person because they have to take more medications which is very dangerous and they need to take more care of themselves so they won't infect anyone with HIV, TB or both. We haven't eradicated TB because two of the three types of TB are drug-resistant, making it very hard to cure. Also, a lot of the time, an infected person will not know that they have TB and will continue on infecting other people, until it's too late. People who are most susceptible to TB like sex workers and drug users are more likely to spread it and less likely to treat it properly. Something that I learned from the articles CDC-TB, MDR-TB CDC, and Tuberculosis NY Times was that bacteria mutates more frequently when people don't finish their doses of antibiotics, which can lead to a mutated form of TB such as MDR-TB. There are different forms of TB, which are MDR-TB (multidrug resistant TB) and XDR-TB (extreme drug resistant TB). Medication and treatment for MDR-TB and XDR-TB is extremely expensive and both are most common in poor
