As for the question, we have to explain how infectious disease progresses including infectivity, invasiveness and portals of entry or exit.
00:12
Infectious disease mainly caused by microorganisms such as bacteria, viruses, fungi, parasites, in which pathogens invade their hosts, and for nutrition or completing their life cycle and then get transmitted to the other healthy horse.
01:28
The transmission of these disease make them more infectious which mainly occurs by vectors which includes flies and mosquitoes.
01:43
The rate of infected person, animals or by contaminated food and water.
02:01
The transmission rate of pathogen is highly ineffective which means the pathogen causing infection very fast and vice versa.
02:12
The invasiveness also defines the rate of infection of any pathogen.
02:34
It tells that how potentially the pathogen is invading the other healthy horse if the potential is high, the invasiveness is high and the infection rate is also high for the pathogen...
