But they might agree that the United States serves as a world marketplace for ideas and experimentation, and that is a very high and central position for us to hold. But it is not a divine right, nor is it a position that is uncontested. The Congress and the people must answer these questions and make this decision over the next several months and years as they decide how much wisdom is thrift, and how much thrift is wisdom. I hope that the following information will be helpful to workers who may be interested in investigating the phenomenon of malaria. Conventional malaria control methods have included vector control using chemical pesticides, mosquito nets, chemotherapy, and, in some cases, a combination of all these methods.
Immunization is still a long way off due to problems of developing an effective vaccine.
Of all the methods used, the most effective and long-lasting solution is the eradication of the vector mosquito Anopheles . Where mosquito control has relied on chemical pesticides, there has been a problem with the mosquito developing resistance to the pesticides as well as environmental side effects stemming from pesticide use. The poor economies of most developing countries such as Zambia have led to breakdown of vector control programs because there are no budget allocations for these programs. In Zambia, mosquito populations actively follow seasonal changes, which implies that malaria transmission follows seasonal patterns. Global climatic changes in Zambia and southern Africa have put a lot of stress on humans and higher vertebrates because of severe, prolonged droughts, which mean less food and less water.
