Transmission of communicable diseases can occur in several ways:
Direct contact: This includes person-to-person contact, such as touching, kissing, or sexual intercourse. Indirect contact: This involves the transfer of pathogens via inanimate objects, like doorknobs, utensils, or medical instruments. Droplet spread: Pathogens are spread through respiratory droplets expelled during coughing, sneezing, or talking. Vector-borne spread: Insects or animals transmit pathogens to humans, such as mosquitoes spreading malaria. Airborne transmission: Pathogens are carried in the air and inhaled by susceptible individuals, such as in the case of tuberculosis.
