heart, nervous system
Rubella

– Feces of an infected person, urine, blood, cough or speak,
when saliva is spread. symptom doesn't appear to the faces.
Contagion is strong, and incidence in a group is high.
– family from 50-60% are infected. If pregnant women become

Mumps
• Overview
– Mumps virus belong paramyxovirus lesson is a RNA virus of 90 ~
300nm.
– Mumps virus infections of the ether, 0.1% formaldehyde,propiolactone, ultraviolet, or 50°c ~ 60°c (20min) with no heat, in 4°c
few days, -20°c days the order will remain infectious.

tenderness, swelling after starting 1-3 days to reach a peak within 3 to
7 broaching the skies.
• cause / pathophysiology
Mumps
– Pathogens
• paramyxovirus (RNA virus)
• This is only one host
– Epidemiology
• Are infected with the respiratory droplets.
• Worldwide trend in winter and 30% have subclinical infection, after receiving
immunity.
– before infection
• Summer dyeing sex virus (Mumps virus), or direct contact with a small parcel
(droplet)
• ,or other contaminated material entering the nose or mouth infection (infection
splash) and, for children 5-15years old are most common.
– incubation

after 9days.

rapid heartbeat, @sweating, and an anxious appearance)
Diphtheria
• prevented
– Preventhing diphtheria depends almost completely on immunizing
children with the diphtheria/ tetanus / pertussis (DTP or DTaP)
vaccine and non -immunized adults with the diphtheria/ tetanus
vaccine.
– for example>>
• DTaP vaccines at 2,4 and 6months of age
• booster doses given at 12 to 18 months
• booster doses given again at 4 to 6 years
• booster shots given every 10years after that to maintain protection
Swine influenza A(H1N1)

Plague
• Symptoms
– Bubonic plague — This form of plague is transmitted by the
bite of an infected rat flea, and it takes its name from the
swollen, infected lymph nodes called buboes that are found
within the lymph system draining the area of the flea bite
– Septicemic plague — This form of plague can develop as a
complication of untreated bubonic plague, when Y. pestis
bacteria spread to the bloodstream and cause a blood infection
called septicemia.
– Pneumonic plague — This form of plague develops when a
victim has inhaled contaminated airborne droplets from an
animal or human whose plague infection has spread to the
lungs, or from spread of the bacteria to the lungs in patients
with bubonic or septicemic plague.
Plague
• Prevention
– Avoid contact with sick or dead animals.
