BIOL10003 Lecture Notes - Lecture 12: Viral Hemorrhagic Fever, Wolbachia, Yellow Fever
Lecture 12 risk that exotic zoonoses will enter australia and new technologies for parasite control. Incubation period (before symptoms appear) is long e. g. rabies red fox common in australian cities: they live close to us. Korean haemorrhagic fever virus in rats, spread via urine. Yellow fever mosquitoes in australia; spreading south with climate change. Epidemics r = pcd r intrinsic rate of infection (a constant); if r<1 no exponential increase, if r=0 no spread. P probability of passing on the disease. C average effective contacts in a year. D duration of infectious period someone with many contacts = hub. An enzyme pumps chloroquine out of vacuoles. A chemical is being designed to block the responsible gene. Using known biology to target pests e. g. juvenile hormone in insects - used as an insecticide, preventing the larvae from developing into adult insects.
