2. All the diseases which come out of the nose or throat are being received in handkerchief which can be well washed by soap and anti-infectious substance.

(i) Viruses lack any cell well of their own.They enter our cells and use our machinery for their life processes.
(ii) They do not have cytoplasm and cell organelles.To multiply they enter the cell of living organism.They use cellular resources of the host to reproduce.
(iii) As viruses lack cells, biochemical process are missing in viruses.Since these biochemical processes are targets of antibiotics, antibiotics do not work on viruses.

(i) common cold
(ii) dengue fever
(iii) influenza
(iv) AIDS

Three most common diseases are:-
(i) Tuberculosis
(ii) Typhoid
