▫️No carrier: Influenza(no chronic carrier) virus,measels,varicella Zoster
▫️ Incubitory carrier : Rubella,Mumps
▫️Milk borne infection : Streptococcal pharyngitis , Diphtheria ,TB (Tubercle mastitis (intestinal TB) )
▫️Chemoprophylaxis : Streptococcal pharyngitis,Pertussis , meningitides(Rifampacin),TB
▫️Animal reservoir: Influenza, Diphtheria (udder),TB(mainly extrapulmonary)
▫️Latent reactivation :TB,Varicella Zoster
🔹Swine influenza (pandemic)
🔹Measles (endemic)
🔹Mumps (Epidemic parotitis)
🔷 Monkey 🐒 pox IA an (out break in 2022-2023)
📍Incubation period:
1- Influenza virus & Common cold 1-2days
2-Avian Influenza:2-8 days and possibly as long as 17 days.
3-Measles : 10-12 days
4-Rubella,Mumps&Varicella Zoster :2-3 weeks
5-Corona:5-6 days, but can be as long as 14 days
6-Streptcoccal pharyngitis:1-3days
7- Pertussis : 7-10days
8- Diphtheria : 2-7days
9- Neisseria meningitides :2-10 days
10-TB:4-6weeksI.p for monkey 🐒 pox 1_21 day
Period of communicability بيلزق في الشخصUntil after all scalps fall+++Replaced by intact skin
📍Period of infectivity:
1-Influenza:Viral shedding begins 1 to 2 days before onset of symptoms and lasts about 1week.
2-Measels: throughout the course of the disease (about 8days), 4 days before appearance of rash and 4 days after appearance of rash.
3-Rubella:Adults: from 5 days before appearance rash (during incubation period) to 5 days after appearance of the rash. - Newborn with congenital rubella: discharge the virus for months after birth till 1 year (about 90 % of them have the virus in most of their oropharynx & extravascular fluids (e.g cerebrospinal fluid, tears, and urine).
4-Mumps: 3weeks
- 1 week before salivary enlargement.
- 2 weeks after salivary enlargement(till it disappears)
5-Varicella Zoster:extends from 1 day before onset of rash to 4 -5 days after rash appears, or until lesions have formed crusts.
♦️Notes ▫️Measels : Usually affects children after the age of 6 months (after the decrease in the transferred maternal immunity).
▫️Rubella: typical rash and cervical lymphadenopathy.
▫️Mumps: life-long immunity-Complications: Orchitis, oophoritis, pancreatities,meningoencephalities, congenital anomalies (1st trimester).-Seroattenuation(Cases)
▫️Corona : -Typical chest imaging findings suggestive of COVID -19 include the following:
- Chest radiography: hazy opacities ,often rounded in morphology ,with peripheral and lower lung distribution
Chest CT: multiple bilateral ground glass opacities(GGO),often rounded in morphology, with peripheral and lower lung distribution
▫️Pertussis: spasmodic coughing, with inspiratory whoop,Begins at birth (no maternally acquired immunity) highest in schoolage.
▫️Diphtheria: Notice the -Pseudomembrane in the posterior pharynx, It can become very large and may Obstruct the airway-For Susceptibility: - Schick test: - It is Cutaneous test to determine whether the circulating antitoxin is sufficient for protection or not. {If (+)… Susceptible, if (-) Immuned}-Culture on Loffler's or Tellurite medium.
▫️Haemophilus influenza:1- Meningitis: Caused by type B encapsulated types . 2- Acute Epiglottitis: It is a rapidly fatal disease because of respiratory obstruction. 3- Acute Otitis media and pneumonia: in children less than 5 years, in adults it causes pneumonia and chronic bronchitis.
▫️Neisseria meningitides:Carriers are the Main source of disease spread in the community.-Episthotonus. - Positive Kerning's and Brudzinsky signs.
▫️BCG vaccine of TB (Intradermal)
