What aspect of medicine saw improvements from WW1 to WW2?

The improvements in public health initiatives from World War I to World War II are significant due to the changing understanding and needs of the population during this period. World War I highlighted the dire consequences of poor public health, which led to many countries reassessing their public health strategies.

During and after the war, there was a greater acknowledgment of the importance of sanitation, disease prevention, and health education. Governments began to invest more in public health infrastructure and initiatives, leading to the establishment of various health organizations and programs aimed at addressing issues such as tuberculosis, maternal health, and nutrition.

Furthermore, the experience gained during WW1 regarding the management of large numbers of injured soldiers contributed to advancements in emergency care and the organization of medical services, which further shaped public health approaches. Comparatively, the other options, such as herbal remedies, homeopathy, and alternative medicine, did not see the same level of systematic improvements or integration into mainstream medical practices during this time period, as public health became more science-based and focused on preventive measures and large-scale health campaigns.
