The virus can only reproduce inside(a) living cells where it multiplies. Aids happen due to a virus called human immunodeficiency virus. This virus belongs to a virus screen out known as the retrovirus. Retroviruses atomic number 18 a type of viruses that are made of the ribonucleic acid or the ribonucleic acid. The RNA makes up for the genetic composition of the retroviruses. HIV first infects the cell. in one case the cell has been infected, HIV uses reverse transcriptase to transform RNA into DNA or deoxyribonucleic acid. The DNA keeps on replicating itself by making use of the cell and its machinery. Merk el also spoke about why symptoms of AID baffle time to show in humans. This is because HIV is a leaden virus. The subgroup of viruses that it belongs to is known lent viruses or slow viruses. Merkel like-wise elaborates on the biological background of terabit. The archetype has also been discussed in class.

Markels explains, rather elaborately six major infectious diseases i.e. tuberculosis plague, typhus, cholera, assist and bubonic plague. Most of the epidemics were due to bacteria. Typhus was caused by a bacterium called Ricktessia. The prevalent of epidemics due to bacteria was particularly emphasized.Merkel makes special reference to Koachs postulate for disease causation in his book. Pathogen is present in all
