Transmission
The foot-and-mouth disease virus can be transmitted in a number of ways including close contact animal to animal spread, long-distance aerosol spread and fomites or inanimate objects, typically fodder and motor vehicles. The clothes and skin of animal handlers such as farmers, standing water, and uncooked food scraps and feed supplements containing infected animal products can harbo
Yellow fever (YF) is a viral haemorrhagic fever transmitted by infected mosquitoes.
Sylvatic (or jungle) yellow fever occurs in tropical rainforests where monkeys, infected by sylvatic mosquitoes, pass the virus onto other mosquitoes that feed on them
The intermediate cycle of yellow fever transmission occurs in humid or semi-humid savannahs of Africa, and can produce small-scale epidemics in ru

Incubation period, serial interval 추정
*serial interval:
Mood is affected by the release of monoamine neurotransmitters including serotonin and norepinephrine.
Lack of neurotransmission at central serotonergic or noradrenergic synapses causes depression.
CRF and depression
Hyperactive HPA axis enhances CRF transmission in the hypothalamus.
Increased arousal, decreased appetite, decreased sexual behavior, and increased heart rate and blood pre
viral genome enters the cytoplasm.
: The viral DNA forms supercoiled mini-chromosome structures upon
entering the host nucleus.
The viral DNA is transcribed into polyadenylated RNA
: terminally redundant because of transcription occurring twice
for some parts of the DNA
3. Newly transcribed RNA enters the cytoplasm once more
& It has two roles.
