Which stage of infection is most severe?
Following the prodromal period is the period of illness, during which the signs and symptoms of disease are most obvious and severe.
The period of illness is followed by the period of decline, during which the number of pathogen particles begins to decrease, and the signs and symptoms of illness begin to decline..
What happens during the incubation part of the disease?
In a typical infectious disease, the incubation period signifies the period taken by the multiplying organism to reach a threshold necessary to produce symptoms in the host.
What stage of infection is most communicable?
In some cases, a person is contagious during the incubation period, while in others the person is not contagious until the illness begins. The amount of time a child remains contagious depends on the infection and the child. Young children are often contagious for longer than older children.
What is the incubation stage of infection?
What Is an Incubation Period? The incubation period is the number of days between when you’re infected with something and when you might see symptoms. Health care professionals and government officials use this number to decide how long people need to stay away from others during an outbreak.
What are 5 ways diseases are transmitted?
Five common ways germs are spread:Nose, mouth, or eyes to hands to others: Germs can spread to the hands by sneezing, coughing, or rubbing the eyes and then can be transferred to other family members or friends. … Hands to food: … Food to hands to food: … Infected child to hands to other children: … Animals to people:
What are the 4 types of diseases?
There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic diseases and non-genetic hereditary diseases), and physiological diseases. Diseases can also be classified in other ways, such as communicable versus non-communicable diseases.
How do diseases cause symptoms?
Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. Disease occurs when the cells in your body are damaged as a result of infection and signs and symptoms of an illness appear.
What are the four stages of natural history of disease?
Events that occur in the natural history of a communicable disease are grouped into four stages: exposure, infection, infectious disease, and outcome (see Figure 1.6). We will briefly discuss each of them in turn.
What can I expect from an infectious disease doctor?
The role of an infectious disease specialist is to review a patient’s medical data, including records, X-rays and laboratory reports. They may perform a physical examination, depending on the type of problem. Laboratory studies are often necessary and may include blood studies and cultures of wounds or body fluids.
What are the 4 stages of communicable illness?
The natural history of an untreated communicable disease has four stages: stage of exposure, stage of infection, stage of infectious disease, and stage of outcome.
What is the clinical stage of a disease?
Clinical disease: A disease that has recognizable clinical signs and symptoms, as distinct from a subclinical illness, which lacks detectable signs and symptoms. Diabetes, for example, can be a subclinical disease for some years before becoming a clinical disease.
What is the acute stage of infection?
An acute viral infection is characterized by rapid onset of disease, a relatively brief period of symptoms, and resolution within days. It is usually accompanied by early production of infectious virions and elimination of infection by the host immune system.
Is there any disease caused by kissing?
Kissing can transmit many germs, including those that cause cold sores, glandular fever and tooth decay. Saliva can transmit various diseases, which means that kissing is a small but significant health risk. It’s not all doom and gloom. Research into passionate kissing has uncovered many valuable health benefits.
What is the infection process?
The Infectious Disease Process. [last update 11/24/03] The infectious disease process includes the following components: (1) agent (2) reservoir (3) portals of entry and exit (4) mode of transmission (5) immunity. Types of agents range from the submicroscopic to the large parasites.
