The process by which a pathogen transfers from one individual to another, leading to the development of an illness in the new host.
The phenomenon where negative behaviors or trends spread from one person to others, similar to how an infectious disease might propagate.
Example:
我々は病気の伝染をくいとめなければならない。
A category of diseases caused by the infection of microorganisms such as bacteria, viruses, or fungi, which spread between individuals in a way that can lead to widespread outbreaks within populations. Preventative measures are critical for public health.
Diseases that are easily transmitted from one person to another, often leading to significant public health challenges and requiring monitoring and control measures.
A type of disease characterized by its ability to propagate through direct or indirect contact among individuals, resulting in clusters of illness that can overwhelm healthcare systems.
Illnesses that are not only infectious but also result in community-wide health concerns, necessitating interventions by health authorities to contain their spread.
Example:
伝染病が発生した。
The characteristic of being capable of spreading from one individual to another, often used in the context of diseases that can be transmitted between people or organisms.
The quality or attribute of an illness that allows it to be passed on to others through direct or indirect contact.
The propensity of a pathogen to cause an infection in multiple hosts, indicating its ability to transfer and establish itself in new environments.
Example:
湿疹も伝染性だって。
A skin condition caused by a viral infection, characterized by the appearance of small, painless, raised lesions that can spread through direct contact.
A contagious skin disease primarily affecting children, manifested by round, wart-like growths that may resolve spontaneously over time.
An infectious dermatological condition caused by a poxvirus, which results in localized nodules on the skin, often requiring no medical treatment for resolution.
