The reason why probability got considerably higher than in the past is that improving percentage of countries introduce new policy regards sexual upbringing. The age of sexual initiation has been reduced a lot and therefore, in plenty countries for instance of eastern Europe there is more and more difficulties such as inter alia increasing percentage of young parents. One of other influential complications related to increasing risk of catching HIV virus is referred to the fact that a variety of people are unaware of the fact they may have problem with it (here). Nonetheless, if they would have done free HIV test just for their own even though they may have observed that they are ill, they would save their partners from similar drama.
That’s the reason why, especially in those countries, where the probability is quite high, appropriate social campaigns should be implemented. Their purpose would be to promote solutions such as free HIV test and to convince people to check themselves in order to stop this virus from further
development. If similar campaigns would be implemented appropriately the risk of catching similar virus would be substantially minimized. Furthermore, if that would be done by everyone, maybe it would be even possible to get rid of this virus on a worldwide scale.
