How immigration from Africa is bleeding the NHS dry

Even the UK government now has to admit that HIV-infected Africans are costing the British taxpayer (in Britain, your taxes finance the health system, it's not some sort of health insurance system) a whole lot of money:

Nevertheless, in 2013, an estimated 38,700 black-Africans were HIV positive and this group constitutes two- thirds (65%, 38,700) of all heterosexual people living with HIV.

And importing Africans, either through legal immigration or the asylum pathway, carries a high probability of getting a HIV patient:

The HIV prevalence rate among black-African heterosexuals is 56 per 1,000 population aged 15-59 years (41 per 1,000 men and 71 per 1,000 women).

And this is a few times higher than the British average, especially when looking at the raw numbers:

In 2013, there were an estimated 107,800 people living with HIV infection (PLHIV).

Which means that 35% of all HIV infected people in Britain are black, but only approximately 3% of the British population are black, i.e. the incidence of HIV is 11 times higher than in the general population.

And each and every of these officially reported HIV cases costs the British tax payer more than 20000 GBP in anti-retroviral medication alone, which means that the unfettered immigration into the British medical system - under what pretense whatsoever (being gay and African makes you get asylum almost automatically, and if you can't get treatment for HIV in your home country, you are almost guaranteed asylum as well), costs the British tax payer some 774 million GBP a year, and these are only the offically reported numbers in that governmental publication. This of course excludes all these cases of costly co-infections, which are extremely common with HIV-infected people.
