Responding to the main allegation in this thread is just hopeless, I will let illuminati wing that one.

As for Helpjava's question, let's ask that question:

Were you keeping track of what deadly diseases have appeared in last 20-30 years and years before that? Your question suggests your concern that the deadly diseases are just appearing now and not in the past. Please check the records, this is not a new problem that "suddenly" occurred.

Sounds like legit question doesn't it? After all, we keep hearing various strains of diseases starting from Africa. Is it just a coincidence that Africa is poor, and allegedly many of the vaccines are tested there first, and the diseases actually start there?

This speculation is not baseless. Large drugs corporations & conglomerates have displayed casual attitude towards the poverty stricken African region; cases of diseases erupting in "test zone" have also been reported. But before we jump to conclusion, perhaps a little bit of research would help.

The link below lists geographical origin of major human pathogens:

Six major diseases are listed and except for Cholera, all five diseases share common origin somewhere in Africa. Are we now saying that these vaccines operations were going on since centuries ago when these cases were first reported? 

So why Africa then? Perhaps this link will shade some light on origin and transmission of diseases in Temperate vs Tropic environment:

http://www.ncbi.nlm.nih.gov/books/NBK114494/

"A higher proportion of the diseases is transmitted by insect vectors in the tropics (8/10) than in the temperate zones."

"A higher proportion (P = 0.009) of the diseases conveys long-lasting immunity (11/15) in the temperate zones than in the tropics."

Those are just the nature of the diseases and insect vectors affected by climates (most part of Africa falls in Tropics zone). What else is unique about Africa? Poverty perhaps? Lack of clean water and food? Don't you think these could be the bigger reason why diseases start there?
