Webchat with Dr Jenny Harries, Deputy Chief Medical Officer for England, Wednesday 25 March at 11.30

What are the symptoms of a mild CV infection? I've had a weird cough and sore throat but it's not all the time. This has been on and off for the last week or so. I have also partially lost my sense of taste which I read today may also be a symptom. My husband has no chest/throat symptoms but is very tired all the time, has pains across his shoulder blades and his chronic lower back pain is much worse for no apparent reason. Are these the signs of a mild CV infection? We're isolating but it's confusing because we don't know what mild CV looks like.

I understand that epilepsy is not a pre-existing neurological condition that makes the person who has it more vulnerable. However, I am concerned by this messaging since some people with epilepsy can stop breathing when they have a seizure and Covid-19 affects the respiratory system. Is it not the case then that some people with epilepsy could be more vulnerable if they catch the virus?

The corona virus currently has a disproportionately detrimental effect on older people, particularly those with underlying health issues. What are the possibilities that, as it continues to spread, the corona virus might mutate into a form that will have a more serious effect on the health of younger people?

Is it known yet if it is possible to contract Covid-19 more than once or does one exposure to it offer immunity?

Firstly, congratulations on your TV appearances. We appreciate your clear and concise approach and your easily understood explanations.

My question is this.

Existing drugs are being currently tested to treat this infection. How long do you think it will be before scientists come up with one or more that will relieve the condition?

Thank you for all your hard work and clear advice during this emergency.

I know people who are going to very great lengths to clean/sanitise their shopping deliveries whilst others say they're just unpacking it and storing it as usual. What is your advice?

Also, (apologies if this is a stupid question, have googled unsuccessfully)... can the virus survive frozen? For example, if I were to put a pack of frozen food into my freezer that had just been sneezed on by a delivery person incubating Covid-19, could the virus be reactivated in the future when the item was defrosted?

Thank you for all you are doing to keep us safe.

My partner is in the financial services and his office is on the side of our house. He normally has 2 staff members but one went home yesterday to self isolate because she felt a bit off. However the other one is still working in the office with my partner and I am worried sick about him and quite frankly myself. I am auto-immune and he has a heart condition. He says I am over-reacting. What do you think?

Will this self-isolating make any difference if you have a brick layer in the family?
