The increasing trend of Non-Communicable Diseases among young adults may invite multiple public health challenges in the future.

ObjectiveTo compare the burden of communicable and non-communicable diseases (NCDs) in the USA and globally, particularly among 15-45 years old. MethodsThe imported data from the WHO Mortality Database portal was analyzed by SPSS. ResultsThe study shows the percentage of death from NCDs out of total death in the USA in 2010 and 2019 were 86.7% and 86.8% which are higher than global rates of 78.1% and 80.2%. Despite a similar death percentage out of total death, the death rate due to NCDs increased from 601.04/100,000 (2010) to 687.99/100,000 (2019) and 790.29/100,000 (2020) globally; and from 693.60/100,000 (2010) to 753.35/100000 (2019) and 795.78/100000 (2020) in the USA. On the other hand, the death rate from communicable diseases were 56.57/100000, 55.52/100000, and 129.47/100000 globally; and 44.63/100000, 43.20/100000, and 151.99/100000 in the USA in the respective years. Young adults of 15-45 years show a higher NCD death rate in the USA with an increasing trend. ConclusionThe USA has a higher NCDs dependent mortality rate relative to the global mortality rate, particularly among the 15-45 years age group. During the COVID-19 pandemic, the relative raising in the communicable disease death rate indicates an interplay between communicable and NCDs.
