will be at high risk of getting coronavirus in his surgery
I think it would be smart, particularly since he is a GP (I'm assuming GP means general practitioner there the same as it does in the states). If he worked in specialty, I think it would be less of a concern. In the states, depending on the specialty, people are pretty good about canceling if they are sick so they don't spread it. The GP is who go to if your ARE sick.
Without knowing more about his practice, I am going to guess that he may become very busy in the coming future? Again, depending on the practice, this is likely to be a very emotionally and physically draining time, potentially making him more susceptible.
For the most part, other than work, I have not gone out much. I went to the grocery store last week and, for the first time, I was "afraid". The store was out of things to wipe the cart down and it wasn't keeping people separated very well in the check out, the cashier wasn't wearing gloves and they didn't clean anything between people. (I did go to another grocery store and TOTALLY different experience, they cleaned everything between each person checking out, they kept distance, there were clerks, cleaning the carts with some solution before you took one) Anyway, I couldn't get out of the first grocery store fast enough. All I
could think of was, I would be crushed if I inadvertently brought germs to my parents or other people I have may have "contact" with.
I am going to go out on a limb and guess your husband may feel the same way. It's stressful worrying about bringing home this infection to someone vulnerable. I read something on the American Diabetes Association website, it said it isn't just about having a higher risk for catching this virus (or other viral infections). If your diabetes is well controlled and you don't have other complications, you may not have an increase risk factor however, if you DO get it, the outcomes can be so much more severe (than the general population).
This is the one thing that keeps running through my head through all this:
Back when I was in elementary school and up, AIDS was a big focus. One of the things they taught that has always stuck in my head was: if you had unprotected sex with someone, you weren't just sleeping with that single person but were also sleeping with everybody else they had sex with before you. With the coronavirus, all I can think of is: When you "socialize" with someone, you are not just socializing with that person but are socializing with everyone they have socialized with before you.
There is a family in New Jersey that has been hit particularly hard. The first New Jersey death was a gentleman who work at a harness race track in New Jersey, I believe it is about four miles out of the New York's earliest epicenter. Before he got sick, he was in contact with a friend of his who was a member of a big Italian-American family (whom he was also friends with). That person, person A came into contact with went to a big family gathering on March 3rd. That family consisted of a matriarch who had eleven children and 27 grandchildren. The matriarch and six of her eleven children got the coronavirus. Her oldest daughter died about March 13th, her second child (and oldest son) died March 18th, the mother died a few hours after her son, also on March 18th, another son died March 19th. They had 1 in stable condition and two others in critical condition as of last week. Just the other day, another of her daughters (who had been in quarantine) tested positive along with that daughter's daughter. So, again, it isn't just about who you come into contact with but whom that person has also been in contact with.
Since your husband's job is going to put him at high risk of coming into contact with people with the virus, technically that would mean that you are also at high risk of coming in to "contact" with people with the virus.
Just my opinion.
