At what age must all deaths be reported?

In Texas, all deaths occurring in individuals younger than 6 years of age must be reported. This requirement is in place to monitor and investigate potential public health concerns and to track any patterns that may arise in infant and child mortality. The importance of promptly reporting these deaths allows relevant authorities to respond to and address any underlying issues, such as health risks or safety concerns.

Therefore, the correct answer reflects the law that mandates reporting of any deaths under 6 years of age to ensure appropriate oversight and intervention by public health officials and medical professionals.
