What is the infectious period of a disease?
Communicability: Period of communicability is the time during which an infectious agent may be transferred directly or indirectly from an infected person to another person, from an infected animal to humans, or from an infected person to animals. Also known as the 'infectious period'.When is Covid most infectious?

Available data indicate that adults with mild to moderate COVID-19 remain infectious no longer than 10 days after symptoms begin.THE INFECTIOUS DISEASE PROCESS/STAGES OF INFECTION
What is the final stage of the infectious process?
– As the host immune system and/or treatments effectively reduce the number of pathogens, symptoms decrease (also called the convalescence stage). – Ultimately, symptoms disappear and the individual returns to health.What are the three phases of infection process?
The different phases in infections include: Infective period. Communicability period.What does the prodromal stage mean?
The term "prodrome " refers to the early stage and symptoms of any condition. Here, a person might notice changes in the way they feel, think, or behave. However, they won't experience symptoms such as disorganized thought or behavior, hallucinations, or delusions.What are the 6 chain of infection?
The 6 points include: the infectious agent, reservoir, portal of exit, means of transmission, portal of entry, and susceptible host. The way to stop germs from spreading is by interrupting the chain at any link. The host is any carrier of an infection or someone at risk of infection.What is the convalescent stage of infection?
Convalescence is the gradual recovery of health and strength after illness or injury. It refers to the later stage of an infectious disease or illness when the patient recovers and returns to previous health, but may continue to be a source of infection to others even if feeling better.What is the example of prodromal stage?
Prodromes may be non-specific symptoms or, in a few instances, may clearly indicate a particular disease, such as the prodromal migraine aura. For example, fever, malaise, headache and lack of appetite frequently occur in the prodrome of many infective disorders.What is a primary and secondary infection?

What is the first stage of an infectious disease?
1. Incubation. The incubation stage includes the time from exposure to an infectious agent until the onset of symptoms. Viral or bacterial particles replicate during the incubation stage.What is the acute period?
Acute illnesses generally develop suddenly and last a short time, often only a few days or weeks. Chronic conditions develop slowly and may worsen over an extended period of time—months to years.What is the convalescent stage?
Convalescence is the period in which the body recovers from a serious illness, injury or surgery. Changes to your lifestyle may be needed to make sure the body has enough time and rest to allow a complete recovery.What is the second level of infection control?
Transmission-Based Precautions are the second tier of basic infection control and are to be used in addition to Standard Precautions for patients who may be infected or colonized with certain infectious agents for which additional precautions are needed to prevent infection transmission.How are infectious diseases spread?
Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn't infected.What are the 4 routes of transmission in infection control?
Diseases can spread in many ways
- Airborne transmission. Airborne transmission occurs when infectious agents are carried by dust suspended in the air. ...
- Respiratory (droplet) transmission. ...
- Sexually transmitted diseases (STDs) ...
- Animal or insect transmission. ...
- Food or water transmission. ...
- Health care transmission.
What is primary infection?
Definition of primary infection: the initial infection of a host by a pathogen that has completed a resting or dormant period.
What are the 4 types of infections?
The four different categories of infectious agents are bacteria, viruses, fungi, and parasites. When studying these agents, researchers isolate them using certain characteristics: Size of the infectious agent.What is secondary infection?
A secondary infection is an infection that occurs during or after treatment for another infection. It may be caused by the first treatment or by changes in the immune system. Two examples of a secondary infection are: A vaginal yeast infection after taking antibiotics to treat an infection caused by bacteria.What is an acute infection?
