I read with concern that the nurse from my home town of Blantyre has now reached critical condition after contracting Ebola.

The situation clearly poses many questions as to how this has occurred, however I wonder about the state of her immune system at the time of contraction. I am aware that many Scots are known to have vitamin D deficiency, particularly at this time of year in the absence of sun.

Vitamin D I understand is very important in defending against viral infection and this may include Ebola. Prevention is much better than treatment and providing vitamin D by supplementation is cheap, easy and fairly quick in deficient cases. The are other natural supplements which can also be taken to raise immunity against viruses, such as olive leaf extract and oregano oil and I feel that for those in high risk situations such as this nurse, these immune boosting supplements should be seriously considered. This could reduce the risk of more tragedies like this...at worst there is nothing to lose.

Regarding the letter in Friday's Evening Times, does the driver who complained about flashing lights not realise that the lorry on his outside probably moved out to let him onto the motorway.

If he then moved up to 60mph the lorry would be left in limbo as it is restricted to 58mph.

The flashing of lights would be the lorry drivers asking you to let him in.

I could not believe my eyes when I went to my local store. Our finances have been seriously drained with Christmas and New Year and yet here they are selling Easter eggs ,jelly and chocolate bunnies. For a minute I thought it was April fool's day. It is about time measures were introduced to stop companies from exploiting the public and in particular children.

Regarding the anniversary of the Ibrox disaster, I was minutes in front of all this, having left before the equaliser, trying to catch the bus back to Pollok. I left stairway 13 and had no knowledge that anything had happened until I got home. I have always felt extremely lucky and I will never forget that day. My heart goes out to the families of those that were lost - they will never be forgotten.
