unfortunately this is the time of year where viral infections are very common.
the best thing to do is repeated thorough hand washing for your entire family.
lysol on the common surfaces is completely safe
wash sheets and linens
what about bleach
as for you being pregnant....it's important for you to stay hydrated
bleach is perfectly fine
in the wash or dilute to wash with
you don't want to mix bleach with any other cleaning chemicals as that can produce a potentially toxic fume.
is water ok to rehydrat with
yes...but you also need to incorporate gatorade or something along that lines to make sure your electrolytes replenish.
potassium goes with diarrhea....so you need to replace it.
good luck and take care
