Impact of HIV/AIDS on patterns of population growth and/or population decline
HIV/AIDS: HIV (Human Immunodeficiency Virus) is a virus which initially remains inactive in animals before causing AIDS (Acquired immunodeficiency Syndrome) which affects the immune system. Since it damages the immune system, people with this virus succumb to other life threatening diseases and infections which eventually cause their death. HIV/AIDS has become a global pandemic due to illiteracy, lack of healthcare, insufficient awareness about contraception etc. Since this virus is mostly transmitted through sexual contact, curbing sexual activities, taking tests and increasing awareness seem to be the only ways of preventing this virus from spreading further.
Sub – Saharan Africa is the most effected region. 66% of all deaths caused by HIV occurred in this region. The overall life – expectancy of individuals is lowered due to this infection. Widespread epidemics have made this disease one of the most vicious or damaging health crisis of modern time.
Countries with epidemics have witnessed an increase in mortality or death rates. Population growth slows down or stops due this disease. This virus has had a devastating effect on the populations all over the world. This disease has become one of the major causes of death globally. Child mortality rates and other demographic attributes like age and sex structure have also been affected by this pandemic.
Patterns of population growth:
Countries with growing population patterns suffer heavy losses to human life, especially in underdeveloped or developing countries where healthcare in inadequate and inefficient. However growing population patterns sustain or endure these losses due to being characterised by high fertility rates.
Patterns of population decline:
Areas or regions where the population is decreasing are severely affected by this disease and the loss of life that ensues. If death rates are left unchecked the overall size of the population deteriorates. Economic and social stability are also compromised. Due to low fertility being one characteristics of patterns to population decline, the overall size of the population decreases significantly. Underdeveloped or developing countries face shortage of labour and basic man – power required to carry out daily agricultural and economic activities or processes which in turn contribute to the stability and overall growth of regions.
Containing the epidemic:
No cure or vaccine has been discovered for this virus (Infection) to date. Hence, for the time being people need to become more aware and learn about the preventive measures which can be implemented to curb the spread of this disease. Although scientists have recently started using supercomputers to improve their understanding this virus and how it interacts with its host. They are also trying to develop patient – specific treatments that could combat the ill-effects of this virus. However, for now the only ways of preventing yourself from contracting such a disease is being aware, making sure your sexual habits don’t expose you to this disease in any way, utilisation of contraception and going through regular medical tests and check – ups. Staying safe and aware are the only methods of preserving ourselves.
