MICROPARA 3. EPIDEMIC PATHOLOGY AND EPIDEMIOLOGY - Also known as outbreak. - Number of cases above than what is expected in a Ø EPIDEMIOLOGY given period of time. - Study of pattern of disease. Example: EPIDEMIOLOGICAL PATTERN Diarrhea diseases GI diseases 1. SPORADIC Food contaminants - Singly on and off or no specific pattern. Note: Infectious Disease: Dengue Note: pasulpot- sulpot. (incubation in the body is one week) Example: Infectious disease that requires a 4. PANDEMIC vector. - word wide in distribution Tetanus, Rabies - simultaneous epidemic Meningococcemia: inaatake around the world ‘yung blood vessels. (Sporadic by nature) Example: COVID19 Note: Spanish Flu of 1918 Words end with “itis” - Influenza inflammation Tuberculosis (Number 1: China) Words end with “enia”- related to blood 5. HERD IMMUNITY Septicemia: bacteria sa blood. ⁃ because of the repeated exposure, the population is 2. ENDEMIC already immune. - Always present but with low number of susceptible. Pathology: Father of pathology is Note: RUDOL VIRCHOW Hindi nawawalan ng cases pero nabibilang lang sa daliri. Epidemiology: father of epidemiology Reason: People are aware and is JOHN SNOW has a solution. Ø PATHOLOGY Example: - Study of disease Malaria - Rudolf Virchow Schistosomiasis (worm in the blood stream inside the liver) INFECTION – entry and Filariasis (elephantiasis) - multiplication of an agent kumakapal ‘yung balat (pathogen) to a potential host. Note: - Chancre: lumalabas sa Why potential? Possible you’re not an syphilis na may spots. ideal host or you have a strong immune - Rheumatic Disease: one of system. the complications kapag madalas magka-tonsillitis STAGES OF ILLNESS - Erisypelas: parang sand - Also known as Spectrum of paper ‘yung skin the disease. - Pathogomonic Signs INCUBATION PERIOD CONVALESCENT - By definition, it is the time - Road to recovery or period of interval between the recovery acquisition of pathogen and appearance of signs and Note: symptoms. - If there’s a complication - Asymptomatic stage of magkakaroon ng permanent infection sequela (hindi na mababalik). Note: DEFERVESCENT - Pumasok na ‘yung pathogen - Onset of complication and nagmu-multiply na. leading to death. - Clueless pa ‘yung may sakit. PRODROMAL CHAIN OF INFECTION ⁃ appearance of the foremost or initial of signs and symptoms. Note: ⁃ Una mong mafe-feel kapag magkakasakit ka. ⁃ Koplikspots sa measles ⁃ Forsheimers Spots ⁃ Enanthem: inside ⁃ Exanthem: outside AGENT - It is the pathogen that causing ILLNESS the disease. - All signs and symptoms associated with the disease appear. RESERVOIR - Gives provision for the Note: survival of the agent. Dito lumalabas ‘yung pathognomonic sign - classic/ specific characteristic of Example: illness. - Inanimate objects (fomites), - Herman Sign of Dengue: yung animals, plants, human pamumula  4 HUMAN RESERVOIR vaginal fluids, vomitus, pus, debridement (burn body) 1.
