Hi Zaini,
Gving a break is a good idea. We stop Exjade everytime there is fever, vomiting or nausea. In simple words, HSC has advised that everytime when there is a suspicion of any type of virus, please stop exjade. The virus go crazy if exjade is administrated. Remember, Little Miss A went to hospital last year in November with severe vomiting and nauea (same scenario).
The only logical explanation I came up with that exjade will increase ferritin in blood as it chelates the iron from the organs, viruses love iron rich envoirnment and multiply fast (just my wild assumption). So giving a break is good.
