I – Infection – may have signs and symptoms of an infection. Sometimes however, you may have an infection and not know it, and not have any symptoms. Keep this in mind especially if you have recently had surgery or an invasive medical procedure, a break in your skin, or you have been exposed to someone who is ill.
Signs and symptoms of an infection
a change in your temperature – 37.5°C or higher or below 36°C. feeling generally unwell – not able to get out of bed. flu-like symptoms – feeling cold and shivery, headaches, and aching muscles. coughing up green phlegm.
Asymptomatic disease is where a person is infected with a disease (or develops a disease; diagnosed) but fails to display any noticeable symptoms. These are also referred to as subclinical diseases or infections.
When germs get into a person's body, they can cause an infection. If you don't stop that infection, it can cause sepsis. Bacterial infections cause most cases of sepsis. Sepsis can also be a result of other infections, including viral infections, such as COVID-19 or influenza, or fungal infections.
a high temperature (fever) or low body temperature. a change in mental state – like confusion or disorientation. slurred speech. cold, clammy and pale or mottled skin.
Sepsis can develop quickly from initial infection and progress to septic shock in as little as 12 to 24 hours. 1 You may have an infection that's not improving or you could even be sick without realizing it.
But antibiotics only treat infections caused by bacteria. They don't work on viruses. The good news is that viral infections usually aren't serious. Most will go away in a few days without medical treatment.
It's important to seek treatment because untreated bacterial infections can lead to serious problems. For example, an untreated infected cut can cause cellulitis, a spreading skin infection. Untreated bacterial infections can sometimes lead to serious, life-threatening conditions.
The common element with most bacterial infections are: Fever. Chills. Pain or discomfort in the affected area.
The treatment for bacterial infections is usually a course of antibiotics. Doctors may prescribe antiviral medications for certain viral infections, but few antiviral medications exist. There are some illnesses that tend to develop due to either bacteria or viruses.
When Antibiotics Are Needed. Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics. We rely on antibiotics to treat serious, life-threatening conditions such as pneumonia and sepsis, the body's extreme response to an infection.
Your doctor may prescribe antibiotics if the symptoms are severe and include high fever along with nasal drainage and a productive cough. Antibiotics may also be necessary if you feel better after a few days and then your symptoms return or if the infection lasts more than a week.
Symptoms in case of acute Bacterial Infections may get resolved spontaneously in a duration of approx. two weeks, without undergoing treatment. However, in chronic cases when the symptoms persist for a longer duration, such as for 10 or more days, there is a need for the consultation with a doctor.
Immediate action required: Call 999 or go to A&E if:
a rash that does not fade when you roll a glass over it, the same as meningitis. difficulty breathing (you may notice grunting noises or their stomach sucking under their ribcage), breathlessness or breathing very fast.
It's clear that sepsis doesn't occur without an infection in your body, but it is possible that someone develops sepsis without realizing they had an infection in the first place. And sometimes, doctors never discover what the initial infection was.
Most people make a full recovery from sepsis. But it can take time. You might continue to have physical and emotional symptoms. These can last for months, or even years, after you had sepsis.
A single diagnostic test for sepsis does not yet exist, and so doctors and healthcare professionals use a combination of tests and immediate and worrisome clinical signs, which include the following: The presence of an infection. Very low blood pressure and high heart rate. Increased breathing rate.
As sepsis worsens or septic shock develops, an early sign, particularly in older people or the very young, may be confusion or decreased alertness. Blood pressure decreases, yet the skin is paradoxically warm. Later, extremities become cool and pale, with peripheral cyanosis and mottling.
If the infection has spread or you have a generalized infection, you may develop other signs and symptoms, such as fever, fatigue, pain, etc. Sometimes however, you may have an infection and not know it, and not have any symptoms.
High heart rate or weak pulse. Fever, shivering, or feeling very cold. Confusion or disorientation. Shortness of breath.
As severe sepsis usually involves infection of the bloodstream, the heart is one of the first affected organs.
