NTD can refer to different things depending on the context. Here are some possible meanings:

• New Tang Dynasty Television: NTD Television is a multilingual American television broadcaster founded by adherents of the Falun Gong new religious movement and based in New York City. The station was founded in 2001 as a Chinese-language broadcaster, but has since expanded its language offerings; in July 2020, it launched its 24/7 English channel which now broadcasts nationwide in the U.S. and UK. NTD has a regular focus on the promotion of traditional Chinese culture and western classical arts, and devotes extensive news coverage to Chinese human rights issues, scrutinizing abuses of power by the Chinese Communist Party.

• Neural tube defects: Neural tube defects (NTDs) are birth defects of the brain and spinal cord. They happen to developing babies in the first month of pregnancy, often before a woman even knows she is pregnant. NTDs can cause serious problems for babies. To help prevent NTDs, women who are capable of becoming pregnant should take a vitamin supplement that has 400 micrograms (mcg) of folic acid every day.

• Neglected tropical diseases: Neglected tropical diseases (NTDs) are a diverse group of 20 conditions that are mainly prevalent in tropical areas, where they mostly affect impoverished communities and disproportionately affect women and children. These diseases cause devastating health, social and economic consequences to more than one billion people. The epidemiology of NTDs is complex and often related to environmental conditions. Many of them are vector-borne, have animal reservoirs and are associated with complex life cycles. All these factors make their public-health control challenging. NTDs include diseases such as dengue, leprosy, river blindness, and sleeping sickness, among others.

In summary, NTD can refer to a television broadcaster, a type of birth defect, or a group of tropical diseases.
