Husband working while I’m vulnerable

hello, can anyone help! 
if you are in the vulnerable category has your partner any rights to stay off work during this period. My husband has taken unpaid leave for a week and 2 weeks holiday to get us thru this “stay at home” period and my 2nd chemo cycle. 
work has told him as he has no symptoms and no one in the house has, he can only do unpaid and holiday. Which I feel is unfair as others are getting full pay if someone in the house has slight symptoms. I know this sounds very selfish but he works in a huge food distribution centre and I am so scared of him bringing the virus home.
