    Deficiency of vitamin (b) A causes keratomalacia. Keratomalacia is a severe condition characterized by the softening and degeneration of the cornea, leading to visual impairment and potentially irreversible blindness. Vitamin A plays a crucial role in maintaining the health of the cornea and promoting vision. Its deficiency can result from inadequate dietary intake, malabsorption disorders, or conditions that increase demand, such as pregnancy. To prevent keratomalacia and other vitamin A deficiency-related conditions, ensuring an adequate intake of foods rich in vitamin A, such as liver, dairy products, eggs, and orange-colored fruits and vegetables, is essential for overall eye health.

    DTP (Diphtheria, Tetanus, Pertussis) vaccine is administered intramuscularly to immunize children against (d) Whooping cough, also known as pertussis. Alongside protection from whooping cough, the DTP vaccine also guards against diphtheria, a bacterial infection causing severe respiratory symptoms, and tetanus, a potentially fatal disease characterized by muscle stiffness and spasms caused by bacterial toxins. Immunization with the DTP vaccine is crucial for preventing these serious infectious diseases in children, reducing morbidity and mortality rates, and promoting overall public health by minimizing the spread of these pathogens within communities.

    Malaria is primarily transferred from one person to another by (c) Anopheles mosquito. These mosquitoes are the main vectors of malaria parasites, transmitting them to humans through their bites. While Aedes mosquitoes (a) are vectors for diseases like dengue fever and Zika virus, and Culex mosquitoes (b) transmit diseases such as West Nile virus and lymphatic filariasis, they are not the primary vectors for malaria. Therefore, malaria transmission predominantly occurs through the bite of infected Anopheles mosquitoes, making them crucial in the spread of this infectious disease.

  4. Jaundice primarily affects the (b) Liver. It occurs due to an accumulation of bilirubin, a yellow pigment, in the bloodstream. The liver normally processes bilirubin, but when it's unable to do so effectively, often due to liver disease or obstruction of the bile ducts, jaundice develops. While theRead more

    Jaundice primarily affects the (b) Liver. It occurs due to an accumulation of bilirubin, a yellow pigment, in the bloodstream. The liver normally processes bilirubin, but when it’s unable to do so effectively, often due to liver disease or obstruction of the bile ducts, jaundice develops. While the liver is the primary organ affected by jaundice, other organs like the spleen (c) and gallbladder (d) can be impacted indirectly, as jaundice may result from conditions affecting these organs, but the liver’s dysfunction is typically the underlying cause of jaundice. The heart (a) is not directly involved in jaundice.

  5. Hemophilia is a (c) hereditary disease. It is a genetic disorder caused by mutations in genes that control blood clotting factors, particularly factors VIII or IX. These mutations result in insufficient clotting proteins, leading to prolonged bleeding and difficulty in blood clot formation. HemophilRead more

    Hemophilia is a (c) hereditary disease. It is a genetic disorder caused by mutations in genes that control blood clotting factors, particularly factors VIII or IX. These mutations result in insufficient clotting proteins, leading to prolonged bleeding and difficulty in blood clot formation. Hemophilia is typically inherited from one’s parents through an X-linked recessive pattern, meaning it primarily affects males. While viral (a), bacterial (b), and fungal (d) diseases result from infections by viruses, bacteria, and fungi respectively, hemophilia is specifically a genetic disorder characterized by abnormal clotting protein production rather than an infectious agent.
