    In reality we identify five stages in the infectious process: incubation, prodromal, illness, decline, and convalescence. The first stage is about the infectious agent being emerged in the body. During the second prodromal stage, the agent continues replicating, which triggers the body’s immune response. The symptoms include fatigue, sleeping disorders, anxiety, mood swings, etc. Illness is the period when the signs and symptoms of the disease are most obvious and severe. During the decline stage, the number of pathogen particles begins to decrease, and the signs and symptoms of illness begin to decline. The last stage is convalescence, when the patient generally returns to normal functions.

    There are 4 stages of infection:

    1. Incubation
    2. Prodrome
    3. Illness
    4. Convalescence

    There are four stages of Infection:

    1. Incubation period- This period is starts from invasion of microorganisms into the body until the appearance of first sign of symptoms. During this period microorganisms multiply to cause infection. The length of incubation period depends on the type of microorganism that causing infection so, it may vary from few hours to days.
    2. The Signs of the Disease- slowly the actual symptoms starts to appear in this phase. this phase may take few hours to weeks.
    3. Disease Itself- With noticeable actual symptoms the disease progress further. the severity of the symptoms and the infection depends upon the susceptibility of the host.
    4. Recovery stage- The symptoms slowly start to disappear, repairing back the body from the disease and this may take from few weeks to months.

    Most infectious diseases have 4 stages:

    Incubation period is the period between exposure to a pathogen and when symptoms and/or signs are first apparent. This hase signifies the period taken by the multiplying organism to reach a population necessary to produce symptoms in the host.

    Prodromal period of an infectious illness is the period between end of incubation period and the point at which the characteristic symptoms of the illness appear. A person in the prodromal stage of an infectious illness often displays nonspecific symptoms, such as fatigue or malaise.

    Acute period is the phase of rapid multiplication of the pathogen with exponential growth and peak in its’ population. Symptoms are very pronounced, both specific to the organ affected as well as in general due to the strong response of the immune system.

    Convalescence period is the time the host recovers gradually and returns to baseline. The pathogen load starts to decline, but may not be completely eliminated immediately, hence the host may continue to be a source of infection even if feeling better.

    Actually these are five stages of infection

    1. Incubation
    2. Prodromal
    3. Illness
    4. Decline
    5. Convalescence

    I think infection does not have specific stages.Sometimes, it happens very quickly and patients may be dead if they are not infused consistent antibiotic.Sometimes, it develops slowly, especially on patients who have immunodeficiency syndrome because the response of body is not strong. Each kind of infection has different symptoms depending on the site of infection.But the common symptoms are fever,increasing or reducing neutrophils,increasing CRP, procalcitonin….Anyway,one of the most important things is finding bacteria, using consistent antibiotics to remove bacteria.

    There are four stages involved in a human’s response to a pathogen.

    1. The incubation stage (silent stage– the pathogen has gained entry into the host and starts replicating)
    2. The prodromal stage (itchy, runny nose, dry eyes, etc.)
    3. The peak (clinical) stage (the disease reaches its highest point of development, severe aches, chills, vomiting, etc.)
    4. The recovery stage (symptoms have all but completely vanished; pathogen has been mostly eliminated)

    Internal infections would be a better name. Or more easily understood.

    Lung infections, GI track infections, urinary track infections, kidney infections.

    You don’t want infections in your vital organs. Seriously.

    Your question is based on a wrong assumption in the developed world. Treatments are getting so much better that the death rate for those hospitalized has dropped by over 75%. We have plenty of effective treatments. But the disease takes a toll and not everyone’s body has sufficient resources to pay the toll.

    In developed counties, you are seeing the death rates remain fairly stable despite increasing percentages being vaccinated. This is because the disease is becoming more and more focused on the unvaccinated, many of whom live together, work together, and socialize together along educational and political lines. So you are actually seeing a downtick among the vaccinated being offset by a serious uptick among the unvaccinated that offsets the gains.

    But to sicken, possibly die, and infect others is the “choice” of the anti-vaxxers. They are silent killers circulating among normal people stabbing their friends and co-workers and family members in the back.

    More people in the US, currently estimated at over 900,000, have died from COVID-19 than in all the was the US has fought in in its entire history. Yet, some people cannot get their heads around the situation of the situation. And people will continue to die as a result.

    Just to make it simple what we say an infection mostly is when a microorganisms like virus, bacteria and fungus …that are forgien to the body invade and start mutlitplying with in our body .

    How to treat or controll an infection depends on what kind of infection it is… generally their are multiple ways one can prevent itself from getting exposed to a certain infectious agent and once infected their are several ways to treat an infection depending on the symptoms, severity, location with in our body and type of microorganism causing the infection ..so for example for bacterial infection we have antibiotic, for viral we use antivirus if necessary and for fungus we use antifungal agents…the list goes on

    Some people are just more socially active than others. Some of them like to continue being socially active even though there’s a disease that’s being spread exclusively through social contact. That’s much of your 10%, with the remainder being the people caught in the inevitable crossfire.
