Hi, I'm writing a short research paper about poverty and illness in sub-Saharan Africa as an assignment. I'd like you to proofread and review it. It's about 900 words long. Thank you in advance.

Poverty and Illness in Sub-Saharan Africa
How would you make a living if you did not have enough money to live off? Money is an essential object for mankind to live on this planet. It is spent on necessary items for people’s lives such as foods, drinks, and clothes. Therefore, in case one did not own any money, it would mean that death is imminent. This notion is based on the fact that there is a significant connection between poverty and illness. Sub-Saharan Africa is an example of a region that is extremely affected by the combination of the two. According to statistics by the World Bank (2016), Sub-Saharan Africa has a population of one billion, and approximately 43 percent of the population is below the poverty line of the possession of less than $1.90 a day. This indicates that 430 million people in the region live with a paucity of money, and no other region is in a worse financial condition in fact (United Nations International Children’s Fund, 2015). Moreover, this social complication may cause people to develop health issues such as pneumonia, diarrhoea, malaria, HIV, and depression, and these health impairments culminate in the patients’ deaths in many cases. Of these health issues, depressive diseases and HIV infection are extremely prevalent in Sub-Saharan Africa and have a strong correlation with poverty.
First, poverty can be a direct cause of depression. Canadian Mental Health Association (2007) explains about the connection between poverty and mental health that people who suffer mental illness often live in chronic poverty; conversely, poverty can be a direct cause for people who live in the adverse financial environment to develop poor mental health. Moreover, Dr. Woldetsadik, an assistant policy analyst at the non-profit, nonpartisan RAND Corporation, examines this phenomenon and states in her article released in 2015 that 75 percent of the people who suffer from depressive diseases do not have access to mental therapy they need due to their inadequate possession of money, which is the cause of the high patient ratio in the region. Therefore, the poor living environment where people have to grapple with their household ledgers may lead them to developing depressive diseases. In addition, most of the patients cannot afford to undergo necessary treatments and there is no way to cure their mental impairments, and this exacerbates their symptoms. Poverty and depression have a strong connection with each other in which the former one intensifies and aggravates the latter one, leading inexorably to a worsening of the situation. In addition to the adverse relationship between poverty and depression, poverty also shows an unfavourable connection with and poses a risk of HIV infection.
A number of Sub-Saharan Africans suffer from HIV infection, also because they live in an indigent environment. According to the article “Global HIV and AIDS Statistics” by AVERT (2015), an international AIDS charity headquartered in England, it is estimated that 36.9 million people are living with HIV across the world, and 26.8 million out of them, accounting for 70 % of the global total, are those who live in Sub-Saharan African region. The organization also mentions that the majority of the patients out of the entire number live in low- and middle- income countries, including many of those in Sub-Saharan Africa. Moreover, the U.S. Department of Health & Human Services (2015) explains about HIV on its official website that HIV infection occurs mainly through sharing needles on drug injection, and having an intercourse without using a condom. In Sub-Saharan Africa’s case, the latter is the one that leads to the region’s high patient number of HIV infection. Health Poverty Action, an international development organization working to strengthen poor and marginalized people in their struggle for health, reports in 2015 that poverty encourages women to engage in sexual activities for money, the environment of which is deleterious to the workers because they have to have an intercourse without a condom used in many cases, which increases the risk of HIV infection. Therefore, being poor is, sad to say, directly related to the increasing number of victims of HIV infection in Sub-Saharan Africa.
In conclusion, poverty and the diseases, depression and HIV infection, are strongly connected with each other, and their relationship is a factor that inceases the number of the illnesses’ patients in Sub-Saharan Africa. The factors that lead to this condition are that the patients do not have easy access to necessary treatments, and some people have to choose to work in a situation where no harm on their health is guaranteed, merely for a little better pay. In order to provide those patients with easy access to necessary treatments, one could donate to NPOs or NGOs that handle medical issues in poor countries. However, while this is relatively simple, it is very difficult to ameliorate the situation of those “pink-collar” works, because the workers do it on their will. An organization could host a campaign where it distributes condoms to inhabitants, consuming funds for charities, so that the number of patients of HIV infection will decline. Eventually, it is the one and only solution for Sub-Saharan Africa to receive some aids from other regions to enhance the quality of the living environments of its inhabitants. Therefore, people who live with sufficient money to make ends meet should participate in whatever campaign that aims to improve the quality of lives of people who live in poverty. People are dying even at this moment, so an immediate action should be implemented by individuals.
