Stages of Infection

Infection happens in the event that an organism like an abacus or virus that infects your body. The infection is rapidly multiplying within the tissues of the body. While there are many causes of an illness, some may cause the immune system to become activated which can cause signs of illness.

Five stages are present in infected:

Incubation

prodromal

illness

Decline

recovery

This article will go over every one of five phases of infection in depth and describe the length of time they last , as well as providing examples of the types of infections.

It will also explain the stages of infection are, particularly in those suffering from HIV.

1. Incubation

The incubation stage comprises the time between the time of exposure to the infectious agent to the time when symptoms begin to manifest.

Bacteria or viral particles reproduce during the incubation phase.

Duration

The exact timing of the incubation phase varies according to the type of illness. Here are a few instances:

Flu

The flu virus can incubate for between 1-4 days, according to Trusted Source, however symptoms may be noticed as early as two days following the time that it is introduced to the body.

Hepatitis B

The time of incubation to hepatitis B virus (HBV) is between 1.5-6 months.

Salmonella

Salmonella, a well-known foodborne bacterium that causes symptoms in the span of 6 hours or 6 to 7 days. It can be caused by:

diarrhea

vomiting

stomach cramps

2. Prodromal

The prodromal stage is the time following incubation, and prior to the characteristic signs of infection develop.

Infections can also be transmitted in the prodromal phase.

At this point the infection continues to replicate and triggers the body’s immune system and some mild non-specific symptoms. The symptoms could include:

low-grade fever

fatigue

Duration

The length of the prodromal stage is contingent on the kind of disease.

For instance the flu is an incubation period that is short, approximately 2 days according to Trusted Source. This means that the prodromal stage could be overlapping with the stage of incubation and the beginning of the illness.

According to the Centers for Disease Control and Prevention (CDC)Trusted Sources state that the virus could spread to other people one day prior to symptoms begin to manifest and for up to 1 week after being sick.

3. Illness

The third stage in the course of infection is clinical disease. This is the stage that a person displays the signs of an infectious disease.

Symptoms

The signs of infection can are different depending on the root source.

In general, those with active infections might be affected by:

febrile

fatigue

headache

The muscles are aching

swollen lymph nodes

Infections of the respiratory tract

The symptoms of respiratory infections like the common cold or influenza, can be seen as:

persistent cough

nose that is runny

Snorting

sore throat

difficulties breathing

Gastrointestinal infections

Gastrointestinal infections can lead to these symptoms:

diarrhea

nausea

vomiting

stomach pain

Appetit loss

Duration

The precise timeframe is dependent on the kind of disease, the quantity of infective microbes present in the body, as well as the level of the immune system. Here are some instances:

Flu

The symptoms can last for as long as one week in the case of many illnesses of respiratory infection, including the flu.

Hepatitis B

Certain infections can last for several weeks or even for years. The symptoms of hepatitis B can last for a few weeks. Source. It could also turn into a chronic condition when the infection persists for longer than six months.

Herpes, chickenpox

Herpes simplex virus (HSV) along with chickenpox (VZV) can be hidden in a dormant condition in nerve cells. These viruses may stay within the body for years before becoming active again. When the VZV virus is activated again the virus, it triggers shingles.

The symptoms of chickenpox usually occur between 4-7 days.

Herpes symptoms can vary in duration based on the type of the infection.

Decline

In the stage of decline, the immune system is able to mount an effective defense against pathogens, and the quantity of infectious particles reduces.

The symptoms will improve gradually.

However, one can get secondary infections at this stage if their primary infection has affected your immune system.

In this stage it is possible for the virus to spread to other people.

Convalescence

The last stage of infection is known as convalescence.

In this phase, the symptoms are relieved and the patient is able to resume normal activities.

The extent of the infection certain people could suffer permanent injury regardless of how well the infection has gone away.

In HIV

HIV affects your immune system. If untreated, HIV progresses into AIDS. The risk of exposure to HIV is when someone comes into contact with bodily fluids which are contaminated with HIV particles.

The CDCTrusted Source list three stages of HIV:

Stage 1 An acute HIV infection

These initial stages of HIV infection are also referred to in the context of chronic HIV infection. HIV is a virus that spreads throughout the body, and it attacks special white blood cells known as CD4+ T cells.

Stage 2 chronic HIV infected

If not treated If untreated, an acute HIV infection can progress into chronic HIV and can persist for several decades.

In chronic HIV HIV continues to reproduce and eliminate CD4 cells. There is a possibility that people do not feel symptoms until this point. But, the absence of symptoms doesn’t mean the infection is gone.

Stage 3: AIDS

If someone with chronic HIV doesn’t receive treatment it is possible that they will develop AIDS.

At this stage, the virus severely affected immunity, making the body vulnerable to the onset of other illnesses.

If AIDS is not treated it is common for a person to live for around 3 years.

Summary

The typical infection occurs with five phases.

The stage of incubation occurs shortly after exposure, and is before symptoms start to appear. The incubation stage may last from hours in the case of some illnesses to days, weeks or even years for other infections.

Following is the prodromal that is characterized by minor, nonspecific symptoms.

In the stage of illness one exhibits the usual signs of infection, like the appearance of a rash on chickenpox or vomiting as a result of food poisoning.

The stage of decline is when the amount of microbes infected decreases and symptoms disappear.

The final stage is called convalescence. In this stage, the symptoms go away and the body starts to heal.

HIV is a three-stage the disease three stages of infection: chronic, acute and AIDS.
