All students operate under the supervision and instructions of an Instructor. Unless they willfully act in contravention of their instructor they cannot be blamed. With the current requirement that aircraft are disinfected between each flight then clear unambiguous instructions: what, when, with and how the aircraft should be cleaned must be detailed by the organisation. Their instructions are those that are put into practice, and in the case of a student they must be overseen by their instructor. Don't ever blame the student they are signed up to learn.
I've lost count on how many times in the media that it is stated, Coronavirus spreads: in water droplets (increasingly it is believed they could be spread airborne dry) exhaled by coughing, sneezing and from speech projection. If a person sneezes into their hands it is believed the virus can also be spread by touch. Whether the virus can be found on surfaces from coughing/sneezing, spit or touch is anyone's guess. Just clean, clean and clean. Theory can come later when all has calmed down and a lot more has been learned.
