Summary:

- The article discusses a study that found a link between the decline of bat populations due to white-nose syndrome and an increase in infant mortality rates in some counties in the United States.
- White-nose syndrome is a fungal disease that has devastated bat populations across North America, leading to significant declines in the number of bats.
- The study suggests that the loss of bats, which play a crucial role in controlling insect populations, has led to an increase in the number of insects that can transmit diseases to humans, including those that can affect infant health.
