I am currently in Egypt (Cairo) right now, and i have been bitten three times on my arms by mosquito's. I was adviced before coming here that injections were not a MUST so due to lack of time i didnt have any...now im worried as what if i have catched any diseases, especially because where im staying theres very poor hygiene and just outside my hotel theres dirt, pollution, wild dogs etc. Is there anything i can do to be cautious once i get back to Britain? Is it possible for me to catch something later? I must stress that the bite marks have gone now, and no reaction from me apart from itchiness, which i applied Salvon For Bites on at that time... Im absolutely fine.
