The reason why probability got significantly bigger than in the past is that more and more countries implement new policy concerning sexual upbringing. The age of sexual initiation has been reduced substantially and consequently, in a lot of countries inter alia of eastern Europe there is improving percentage of complications such as for example increasing number of young parents. One of other popular complications referred to increasing risk of catching HIV virus is related to the fact that many people are unaware of the fact they may have problem with it (website). Nonetheless, if they would have made free HIV test just for their own even though they may have discovered that they are ill, they would save their partners from such drama.
Hence, exceptionally in those countries, where the probability is quite high, appropriate social campaigns should be implemented. Their target would be to promote options such as free HIV test and to convince people to check themselves in order to stop this virus from further
growth. If this kind campaigns would be introduced sufficiently the probability of catching this kind virus would be considerably minimized. What is more, if that would be done by everyone, maybe it would be even possible to get rid of this virus on an international scale.
