What is the contagious period of a disease?
The contagious period is the amount of time during which a sick child can give the disease to others.
For major illnesses (such as hepatitis), a child will need to stay at home or in the hospital until all chance of spread has passed.
For minor illnesses (like the common cold) the guidelines are less strict..
Whats the difference between Flu A and Flu B?
Unlike type A flu viruses, type B flu is found only in humans. Type B flu may cause a less severe reaction than type A flu virus, but occasionally, type B flu can still be extremely harmful. Influenza type B viruses are not classified by subtype and do not cause pandemics.
What is the best way to prevent the spread of infection?
Preventing the Spread of Infectious DiseasesWash your hands often. … Get vaccinated. … Use antibiotics sensibly. … Stay at home if you have signs and symptoms of an infection. … Be smart about food preparation. … Disinfect the ‘hot zones’ in your residence. … Practice safer sex. … Don’t share personal items.More items…
What is the infectious disease 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.
What flu is going around 2020?
“Nationally, flu activity has been elevated … and continues to increase; this represents somewhat of an early start to the U.S. flu season,” said Scott Pauley, a press officer for CDC. “Flu activity is currently being caused mostly by influenza B/Victoria viruses, followed by H1N1 viruses and H3N2 viruses.
Are viruses contagious before symptoms?
You’re contagious before you have symptoms — during the incubation period, when the virus enters your system. And just because you feel better doesn’t mean those around you are safe. In fact, you’re still contagious after symptoms subside, carrying a bacterial or viral infection that can spread to others.
What does incubation period mean for a virus?
The incubation period is the time from exposure to the causative agent until the first symptoms develop and is characteristic for each disease agent.
Why do viruses have incubation periods?
The infection of multiple cells in the body and subsequent replication of the virus takes time. While the virus remains at low levels, it can neither be detected nor transmitted. This is why this time is known as the virus’ incubation period.
What is a Fomite * 5 points?
A fomite (/ˈfoʊmaɪt/) or fomes (/ˈfoʊmiːz/) is any inanimate object that, when contaminated with or exposed to infectious agents (such as pathogenic bacteria, viruses or fungi), can transfer disease to a new host.
What are the 5 stages of infectious disease?
The five periods of disease (sometimes referred to as stages or phases) include the incubation, prodromal, illness, decline, and convalescence periods (Figure 2).
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 disease has the longest incubation period?

Which is worse flu A or B?
In the past, it was thought that infection with influenza A was more severe than infection with influenza B. However, a 2015 study in adults with influenza A and influenza B found they both resulted in similar rates of illness and death.
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 stages of infection cycle?
The six links include: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. The way to stop germs from spreading is by interrupting this chain at any link.
What is the difference between incubation period and communicable period?
The period between exposure and infection is called ‘latent period’, since the pathogen is present in a ‘latent’ stage, without clinical symptoms or signes of infection in the host. The period between exposure and onset of clinical symptoms is called ‘incubation period’.
Can you get influenza B twice?
It is possible to get the flu twice during the same flu season. Since there are two types of flu strains – influenza A and influenza B – if you get influenza A, you can also get influenza B.
What are the 6 modes of transmission?
Modes of transmissionDirect. Direct contact. Droplet spread.Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
How do contagious diseases spread?
Contagious diseases (such as the flu, colds, or strep throat) spread from person to person in several ways. One way is through direct physical contact, like touching or kissing a person who has the infection. Another way is when an infectious microbe travels through the air after someone nearby sneezes or coughs.
How do you calculate period of exposure?
Determining the Period of ExposureIdentify the peak of the outbreak, which is the time period then the largest number of cases occurred.Count back from the peak, the average incubation period for disease. … Identify the earliest case in the outbreak and count back the minimum incubation period.More items…
What is a communicable period?
The period of communicability is the time period during which an infected person can spread their infection to others. It is expressed as a range from the earliest time to the latest time infected people can be communicable to others.
