Communicable

Good conductors of heat are usually good conductors of electricity, but that puts the causal relation backwards. Conduction-band electrons can't help but transport kinetic energy, which--randomized--is heat. Putting heat before electricity is reasonable only because of the rarity of materials like diamond that conduct heat via the quasi-particles called phonons, which are communicable crystal-lattice vibrations.

An increased vaccination rate for children resulted in a concomitant decrease in communicable diseases.

In addition, progress has been made in reducing deaths from communicable diseases and maternal, newborn and nutritional disorders.

Gender dysphoria isn't communicable.

(but the last two are not interchangeable in formal registers)
