Explanations:Malaria is a significant global health issue that affects millions of people worldwide. The disease is caused by Plasmodium parasites, which are transmitted to humans through the bites of infected female Anopheles mosquitoes. Malaria is particularly prevalent in tropical and subtropical regions, where the climate is conducive to the survival and reproduction of the mosquitoes that carry the parasite.
The impact of malaria is most severe in developing countries, where healthcare infrastructure may be limited and resources for disease control and prevention are often scarce. However, it is important to note that malaria is not confined to developing countries alone. Even in some developed countries, there are occasional cases of malaria, often due to travelers returning from endemic regions or through local transmission in areas where the mosquito vectors are present.
Despite significant efforts by global health organizations and national governments to control and eliminate malaria, the disease remains a major public health concern. Factors such as climate change, urbanization, and the emergence of drug-resistant strains of the parasite have complicated efforts to eradicate the disease. Additionally, the socio-economic conditions in many affected regions can hinder the implementation of effective control measures.
Therefore, the statement "Malaria is still a major disease in part of the world" is true. It reflects the ongoing challenges in controlling and eliminating malaria, particularly in regions where the disease is endemic and where the necessary resources and infrastructure for effective disease management are lacking.
