Surely it is easier to spread through a living host?
In: 3
more often than not these pathogens are NOT trying ot kill their host. the fact they end up dead is a sideffect of how they operate, in fact some of the more dangerous pathogen either will actively not kill its host, or if that is unavoidable will be able to spread evne after the host expires.
for viruses this is because they are hijacking Cells to take over their replication systems ot multiply and will do so until the cell outright bursts with the copies. now this isnt an intentional thing its just that viruses are extremely simple structures that only have one goal and wont care bout anythnig else ot accomplish it : multiply.
for parasites the issue is that the parasite is leeching something the body needs to function, in order for them to grow and spread. for instance a tapeworm that gets itself in your GI will literally steal food from you , and if not for the fact this gets extremely painful later on it will happily kills its host by starving them, or perforating the GI tract ot infect other organs(most likely spilling the contents of the GI into the body killing you with Sepsis)
for some pathogens the issue isnt the pathogen itself even, but how the body is gonna rect to it. you can legitimately die from your own immune system gonig overboard.
