The scenario mentioned here is one of the shortcomings of staying in the hostel... But taking note of this at the initial stage of staying in the hostel should not be ignored... For instance, during my stay in the hostel, I made sure I boil water before taking my bath, I do drink sachet water, if I have no money to buy water, my mom (now late) bought me a water bottle that could keep water warm for long, I took my hygiene so serious because I new I will fall sick if I don't take care.
And I made it through without ill-health. I'm very happy with the friends I made then in the hostel, in fact, it was through one of my friends that I get to know about steemit.com.

This is why any student reading this article should please prioritise his/her health while in the hostel.

Thanks so much for this comment brotherly.
