Which of the following is true regarding reportable poultry diseases among the options?

• A. Fowl Cholera And Virulent Newcastle Disease
• B. Newcastle Disease And Highly Pathogenic Avian Influenza
• C. Marek's Disease And Highly Pathogenic Avian Influenza
• D. Highly Pathogenic Avian Influenza And Infectious Laryngotracheitis

Answer: (B)

Reportable diseases are those that must be reported to animal health authorities because they can spread quickly, cause high mortality, and affect trade. Among the options, Newcastle Disease when caused by a virulent/velogenic strain and Highly Pathogenic Avian Influenza are the ones typically mandated for reporting. Their severe impact on poultry health and the potential for rapid regional or international spread makes notification and rapid response essential. The other diseases listed—Fowl Cholera, Marek’s Disease, and Infectious Laryngotracheitis—are important poultry pathogens but are not broadly designated as reportable in the same way, so they do not fit the standard definition of reportable diseases as strongly.
