What recent health issue was declared by the Department of Health in the U.S.?

The declaration of the human case of the flesh-eating parasite known as the New World Screwworm is significant as it highlights a rare but serious health concern. The New World Screwworm is a parasitic fly whose larvae can infest the wounds of living animals, including humans. While it was historically a severe issue in livestock, recent cases in humans have raised alarms regarding its potential spread and the implications for public health.

In certain instances, individuals infected with this parasite require medical attention to address the resultant severe infections. The health community's focus on this issue underscores the importance of surveillance and rapid response to emerging health threats, particularly those that can lead to severe outcomes if left unaddressed. This situation is notable given the rarity of such infections in humans and reflects ongoing challenges in managing zoonotic diseases, which transmit between animals and humans.

The other options, while also concerning health issues, do not encapsulate the recent developments surrounding the New World Screwworm as prominently.
