1
give a person or animal a disease
to make a person, animal, or body part sick by putting germs, a virus, or bacteria into it
Vzorec užití:
to infect [someone/something] with [a disease]
Častá chyba:
Learners sometimes say *"He was infect by the virus"* instead of *"He was infected by the virus"* (past participle needed). Another common mistake is confusing *infect* with *affect*; *infect* is only about disease or something spreading like a disease, while *affect* is about causing any kind of change.
Synonyma
contaminate (can refer to making something dirty or unsafe in general; less specific to organisms growing inside the body)
|
transmit (focuses on passing a disease from one person to another, not on what happens inside the body after)
|
infectious (adjective form; describes the disease or agent rather than the action)
Antonyma
cure (means to remove a disease from someone, the opposite of causing disease)
|
vaccinate (means to protect someone against infection rather than cause infection)

contaminate things with germs
to put germs or harmful bacteria into water, food, air, or other things so that they can make people or animals sick
Vzorec užití:
to infect [something] with [germs/disease]

Synonyma
contaminate (very close in this sense; can also include non-biological pollution like chemicals or dirt)
|
pollute (focuses on making the environment dirty or unsafe, not necessarily with living organisms)
Antonyma

spread a feeling or attitude
to make other people feel or think the same way as you do, in a strong way that spreads quickly like a sickness
Vzorec užití:
to infect [someone/a group] with [an emotion/attitude]

Learners may overuse this figurative sense and say things like *"The news infected me"* when *"The news upset me"* is more natural. Use *infect* when a feeling or idea spreads from one person or group to many others, not just for a single reaction.
Synonyma
inspire (usually positive; focuses on encouraging or motivating, without the negative or uncontrollable feeling of 'infect')
|
poison (strongly negative; suggests harming thoughts or relationships, similar to a very harmful infection)
|
permeate (more formal and neutral; describes something gradually spreading through a group or space)
