Pneumonia is a respiratory infection that directly affects on lungs. It can cause inflammation of the alveoli or alveoli in one or both lungs. Although fever is a common symptom of pneumonia, a person can develop pneumonia without having a fever. Fever means that a person’s body temperature reaches 100.4ºF (38ºC) or higher.

 It occurs in response to body infections. Although fever is a common symptom of pneumonia, it may not happen in some people. This article will discuss who may not have a fever with pneumonia. You will also look at other symptoms of pneumonia and when to see a doctor.

What Is Pneumonia?

Pneumonia is a viral, bacterial, or fungal infection of both lungs. Physiologically, when white blood cells attack invading bacteria, viruses, or fungi in the body, the infection can cause inflammation of the air sacs (alveoli) in the lungs.

 Infection can cause pus and fluid to accumulate in the air sacs, causing you to expect sputum and shortness of breath. Although pneumonia can affect people of any age or gender, it occurs more frequently in people with weakened immune systems and is usually more severe.

This is why the elderly and young children are more susceptible to infection. This is why pneumonia is of particular concern to people suffering from chronic diseases such as human immunodeficiency virus (HIV / AIDS), cancer, or other underlying diseases, as well as people undergoing major surgery.

Symptoms of Pneumonia

Sometimes what makes pneumonia difficult to treat is that it has some of the same symptoms as the common cold or flu. 

Signs of pneumonia usually include:

• Fever 
• Chills 
• Cough 
• Thick colored sputum 
• Shortness of breath 

Pain when breathing or coughing:

Headache 

Nausea and/or vomiting 

Diarrhea 3 

The severity of symptoms depends on your health; pneumonia is more difficult to control and shows more severe symptoms in people who have underlying lung disease. Symptoms may vary with age. For example, pneumonia in the elderly (over 65 years) and some immunosuppressed patients may be accompanied by confusion. Babies and young children under 2 years of age may experience breathing difficulties, feeding problems, blue skin or lips, irritability, and decreased urine output.

Pneumonia Without Fever

Fever is not a disease in itself; on the contrary, it is a physiological response to disease. When a fever occurs the body raises its temperature to help eliminate pathogens and fight infection. 4 Therefore, pneumonia without fever often represents a reduced immune response. Certain groups of people tend to have weaker immunity, including 

• Adults 65 years and older 
• Pregnant women 
• Newborns, especially premature persons 

 Infants and young children under 23 years of age. In addition, various other conditions can also affect immunity. These include 

• Human Immunodeficiency Virus (HIV / AIDS) 
• Chemotherapy for cancer
• Taking certain drugs such as corticosteroids or other drugs that suppress immune function
• Autoimmune diseases such as lupus, multiple sclerosis, and rheumatoid Arthritis
• Having organ or bone transplantation 
• Taking drugs, alcohol, or smoking 
• Exposure to dust,

Chemical fumes or second-hand smoke1 People with heart or lung diseases are also more likely to develop pneumonia without fever, including 

• Cystic fiber Chronic obstructive pulmonary disease (COPD) 
• Asthma
• Emphysema
• Bronchiectasis
• Untreated diabetes 
• Dementia 
• Acute

In addition, those who develop “walking pneumonia” (common pneumonia caused by Mycoplasma pneumoniae infection) The person may not have a fever or the fever is greatly reduced. Ambulatory pneumonia is mild and highly treatable and rarely requires hospitalization.

 Regarding pneumonia without fever, it is important to remember that it is still potentially dangerous. It often appears because the patient is already sick or more likely to get sick. The intensity of symptoms varies from mild to very severe. Pay attention to how you feel, and don’t be afraid to ask for help if your symptoms worsen.

Complications

Although most cases of pneumonia can be effectively controlled, if left unchecked, it can be particularly dangerous. what happens? Here is a quick breakdown: 

Shortness of breath:

Severe inflammation and fluid accumulation in the lungs can cause very severe breathing difficulties, especially for those who already have lung diseases such as asthma or COPD. Respiratory failure can become severe and require urgent care. 

Lung abscess:

This is pus, a thick yellow or green fluid that accumulates in the lung cavity. Lung abscesses must be drained and, in some cases, must be surgically removed. 

Bacteremia

This is the spread of bacteria that cause pneumonia into the blood, which can become particularly troublesome. Bacteria can spread to other organs and cause dangerous conditions such as kidney failure and meningitis (a fluid infection that surrounds the brain and spine). 

Pleural effusion:

The tissue that lines the chest cavity and surrounds the lungs may become diseased or inflamed, causing the lungs to fill with fluid. It is treated by draining fluid with a catheter or chest tube and sometimes requires surgery.

When to Call Your Doctor or 911

If you suspect or have been diagnosed with pneumonia, it is important to understand how you feel. Tell your doctor if you experience any of the following: 

• Chronic shortness of breath or difficulty breathing 
• Persistent fever and production of large amounts of mucus. If you have the following

conditions, please call 911:

• Shortness of breath or difficulty breathing even at rest
• Increased chest pain and discomfort
• Confusion or cognitive difficulties

Diagnosis

Because pneumonia can cause symptoms similar to other diseases, the correct diagnosis usually requires a two-stage process. The doctor must determine the cause of the condition and test whether it is caused by bacteria, viruses, or fungi.

Diagnosis may involve the following: 

• Assessment and assessment of health status is the first step. The doctor will review your medical history, evaluate current symptoms, and perform a physical examination. An important initial step is to listen to your lungs with a stethoscope.

• A chest X-ray can show how much fluid there is in the lungs and the pattern of inflammation. This allows the doctor to understand the severity and progress of your case. 

• A blood test determines your immune system’s ability to fight pneumonia. Usually, a complete blood count (CBC) is required to measure the levels of all three types of blood cells (red blood cells, white blood cells, and platelets). 

• Blood culture can also be performed. This can detect whether the infection has started to spread from the lungs to other parts of the body.

• Pulse oximetry is a test of the amount of oxygen in the blood, which may be necessary in the case of severe pneumonia. If the level is too low, the infection may prevent your lungs from working properly. In more severe or severe cases, especially those involving weakened immunity, additional tests may be required, including Bacterial, or fungal infection. 

• A computed tomography (CT) scan of the chest to check for lung injury or other complications. These types of images are based on multiple X-rays to create a 3D representation of the affected area. 

• A culture of pleural fluid is required to assess whether bacteria or fungi have spread to the pleura, which is the tissue on the outside of the lungs. And runs through the inside of the chest cavity. This requires testing liquid samples surrounding these issues. 

• Bronchoscopy involves the use of an endoscope (a camera located at the end of a special adjustable tube) to visually assess the airway. Using this device, the doctor can view the video of the inside of your lungs.

Treatment

The treatment of pneumonia depends on the cause of the disease; for example, methods that are effective for bacterial pneumonia are not effective for the type of virus. The following is a list of treatments for each type of pneumonia: 

Bacterial pneumonia:

 The main treatment for bacterial pneumonia is antibiotic drugs. The specific choice and duration of antibiotics depend on your general health, other medicines you are taking, and the severity of your case. The use of over-the-counter medications, comfort measures, and breathing exercises can also help, and severe cases require hospitalization. 

Viral pneumonia:

The challenge of viral pneumonia is that there are not many drugs that can eradicate it. If the flu virus causes pneumonia, antiviral drugs, such as Tamiflu (oseltamivir) and Relenza (zanamivir), can help relieve symptoms. Respiratory therapy and over-the-counter medications can also help. 

Fungal pneumonia:

Antifungal drugs are the first-line treatment for fungal pneumonia, including triazole drugs such as Sporalax (itraconazole), Diflucan (fluconazole), and amphotericin.

Prognosis

Generally speaking, the success of pneumonia recovery depends on your health. Most otherwise healthy adults can relieve symptoms relatively quickly with treatment. That is if pneumonia is allowed to develop, or if you are in a vulnerable or immunosuppressed population, the disease can be fatal. In rare cases, even after a full recovery, there will be long-term effects. For example, children with pneumonia may experience difficulty breathing throughout their lives. Chronic effects can lead to: 

• Decreased ability to exercise and stay in shape
• Worsening of heart disease 
• Decreased cognitive impairment and mental function 
• Decreased overall quality of life
