Question

Which portal of entry is associated with the transmission of anthrax, tetanus, and rabies?

Options

• Respiratory tract

• Urogenital tract

• Digestive tract

• Skin

Answer 1

The skin serves as the portal of entry for anthrax, tetanus, and rabies. These pathogens enter through abrasions or wounds in the skin. Tetanus spores enter through puncture wounds, anthrax spores through skin lesions, and the rabies virus typically enters through bite wounds, demonstrating how these diverse pathogens share the skin as their common route of entry.
