CHain of infection
The chain of infection is a crucial concept in understanding and preventing the spread of infectious diseases. It outlines the sequential events necessary for an infection to be transmitted from a source to a susceptible host. In this mind map, we will explore the components of the chain of infection, including the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. By visualizing this interconnected chain, we can better comprehend how infections propagate and identify key points for intervention and control.

This infographic offers an in-depth analysis of epidemiological study designs, essential for public health research. It categorizes and describes various methodologies including experimental, cohort, case-control, and cross-sectional studies. It further delves into each type's specific approaches, such as selection of cases, control matching, and the calculation of statistical measures like risk and odds ratios. This visual guide is ideal for students, researchers, and public health professionals seeking to understand or conduct epidemiological research.

- Chemical Mediator Inflammation and Information about it
The role of chemical mediators in inflammation is a complex and essential aspect of the body's immune response. This mind map will delve into the various chemical mediators involved in the inflammatory process, including cytokines, prostaglandins, leukotrienes, and histamine. By visually mapping out the interactions and functions of these chemical mediators, this mind map aims to provide a comprehensive overview of how they contribute to the initiation, propagation, and resolution of inflammation.

Chain of infection
Chain of infection
Infectious agent
An infectious agent is a microorganism, such as bacteria, viruses, fungi, or parasites, that causes disease.
Different types of infectious agents have specific modes of transmission and characteristics.
These agents can enter the body through various routes, such as respiratory, digestive, or skin.
Reservoir
A reservoir is a place where infectious agents can survive, grow, and multiply.
Reservoirs can be living organisms (humans, animals) or inanimate objects (water, soil).
Ex: C.b in soil but the source of infection from canned food
Animal resrvoirs - Zoonosis
Brucellosis - cows and pigs
Anthrax - sheep
Plague - rodents
Trichinellosis - swine
Tularemia - rabbits
Rabies - bats - raccons - dogs
NA
West nile encephalitis - birds
Monkeypox - dogsor prairie
NEW IN HUMANS
HIV/AIDS
Ebola
SARS
Enviromental reservoirs
Histoplasmosis - in the soil - fungal agents
Legionnaires - water supplies
Portal of exit
The portal of exit is the route through which infectious agents leave the reservoir.
EX
Influenza + TB - RST
Schistosomes - urine
cholera vibrio - feces
scabiei - skin lesions
Rubella - syphilis - toxoplasmosis - Hepatits B - malaria - BLOODborne agents
Malaria - Athropods
Modes of transmission
Modes of transmission are the ways in which infectious agents are transferred from one host to another.
Direct contact
Mononucleosis - kissing
Gonorrha - person to person contact
Hookworm - contaminated soil
Droplet spread
>5 microns
Pertussis - meningococcal
Airborne dust
Droplet nuclie - <5 microns
Measles
Vehicles
Passive carring - HAV
C.b in canned food
Vectors
Biologic transmission - malaria or guinea worm
Mechanical means -
Flies - Shigella in their appendages
Fleas - Yersinia pestis( plaque) in gut
Portal of entry
The portal of entry is the route through which infectious agents enter a susceptible host.
Influenza use RST as enetery and exit
Gastroenteritis - fecal-oral entery --> feces( and no washed hands) --> vechicle --> oral
Hookworm - skin
Syphilis - mucous membrane
HBV and HIV - blood
Susceptible host
A susceptible host is an individual who is at risk of acquiring an infection from an infectious agent.
Toxoid - toxin that been deactivated but retains its capacity to stimulate production of toxin
