Question

anna has been diagnosed with poliovirus. what most likely caused this virus? (1 point)
she shared a dirty needle when injecting drugs with an acquaintance.
she didnt thoroughly wash her hands after using the restroom.
she consumed food that wasnt cooked to a safe temperature.
she inhaled droplets from a nearby strangers cough.

Explanation:

Polio is mainly transmitted through the fecal - oral route. If a person doesn't wash hands thoroughly after using the restroom (where fecal matter may be present in a contaminated environment), they can ingest the poliovirus. Sharing a dirty needle is more associated with blood - borne viruses like HIV or hepatitis. Consuming under - cooked food (if related to polio) is less common as polio transmission is more about fecal - oral (not just general food safety in the sense of cooking temperature for bacteria etc. in a typical context). Inhaling droplets from a cough is more for respiratory viruses.

Answer:

She didn't thoroughly wash her hands after using the restroom.
