Do you have evidence for this assertion or is it just an assumption?

Never seen doctors and nurses wear masks in operating theaters etc.?  Not sure what point you are trying to make...

I absolutely do have evidence.

But maybe it's just all a sad costume party? :popcorn:

Well I'd be interested to see it, because I took the trouble to check the CDC recommendations for infection control (the CDC ones simply because they were easy to find, follow links here [url=https://www.cdc.gov/hai/prevent/ppe.html]https://www.cdc.gov/hai/prevent/ppe.html[/url]) and these do not recommend the routine wearing of masks by medical staff for infection control, only in specific circumstances. Next to each recommendation they call out the strength of the evidential basis for that recommendation. Folks here are treating masks as some kind of magic panacea, they are not. The CDC do recommend giving masks to patients who have or may have a infection that is airborne. They do recommend medical personnel to wear masks and face shields when undertaking some procedures vis: "procedures and patient-care activities that are likely to generate splashes or sprays of blood, body fluids, secretions and excretions" and "During aerosol-generating procedures (e.g., bronchoscopy, suctioning of the respiratory tract , endotracheal intubation) in patients who are not suspected of being infected with an agent for which respiratory protection is otherwise recommended (e.g., M. tuberculosis, SARS or hemorrhagic fever viruses), wear one of the following: a face shield that fully covers the front and sides of the face, a mask with attached shield, or a mask and goggles (in addition to gloves and gown)". They do recommend wearing masks when treating patients with certain respiratory diseases (partially called out above).

Masks are not called for in medical settings anywhere near as much as you'd imagine if you get your information from stock photography and film and television drama. I can't remember the last time I saw a real live doctor or nurse wearing a mask in real life - including lying on my back in A&E/resus/on wards watching other patients being treated around me.

In a pandemic situation I imagine that a lot of medical personnel are wearing masks as a routine precaution, but that doesn't necessarily imply that there's a good evidential basis for doing so - amazingly doctors and nurses are as susceptible to cargo cults as much as the rest of us. There is evidence to follow a recommendation to use one when actively treating a patient with a suspected or known serious respiratory infection.
