About Polio
The disease causes of polio are as follows:
- Polio is caused by the poliovirus, which enters the environment through the feces of an infected person.
- In areas with poor sanitation, the virus can spread through contaminated water or food.
- Direct contact with an infected person can also transmit the virus.
Non-modifiable risk factors of polio are factors cannot be changed or controlled. These include:
- Age: People of all ages can get polio, but children under 5 years old are most susceptible.
- Immune system weakness: Individuals with weakened immune systems due to other medical conditions are more vulnerable.
Modifiable risk factors of polio can be influenced or changed. These include:
- Traveling to areas where polio is common or widespread, such as Pakistan and Afghanistan.
- Living with someone infected with polio.
- Working in a laboratory where live poliovirus is kept.
- Lack of immunization: Those who have not been vaccinated against polio are at higher risk.
It's important to note that vaccination is the most effective way to prevent polio. Consult with your healthcare professional for personalized advice on vaccinations and other preventive measures.
The most common early symptoms of polio include:
- Fever
- Headache
- Malaise (general feeling of illness)
- Aseptic meningitis (inflammation of the membranes surrounding the brain and spinal cord)
As polio progresses or reaches a higher severity, the following symptoms may occur:
- Severe headache
- Stiff neck and back
- Deep muscle pain
- Temporary abnormalities of skin sensation
- Muscle spasms
- Urinary retention (difficulty emptying the bladder)
- Muscle weakness and paralysis, usually starting in the legs but can also affect the arms and abdomen
- Difficulty speaking and swallowing if the muscles of the neck and throat are affected
In some cases, polio can lead to life-threatening paralysis of the muscles involved in breathing, which can result in death. It's important to note that not everyone with polio will experience these severe symptoms, as most cases are mild and resolve on their own. If you have recovered from polio and are experiencing muscle weakness, pain, fatigue, or other symptoms, you should speak to your doctor about the possibility of post-polio syndrome (PPS).
To diagnose polio, doctors typically perform the following examinations, tests, and procedures:
- Medical history: Doctors ask if you had polio in the past, whether you had some recovery after the infection, and if you had a long period without symptoms before your current problems started.
- Physical examination: Doctors assess symptoms such as impaired reflexes, back and neck stiffness, and difficulty lifting the head while lying flat.
- Throat, stool, or cerebrospinal fluid sample testing: Labs test these samples for the presence of the poliovirus.
To determine the severity of polio, additional examinations, tests, and procedures may include:
- Neurological exam: This exam helps identify muscle weakness and atrophy (loss of muscle mass).
- Electromyogram (EMG): A muscle test that measures electrical activity of muscles to evaluate how well the nerves are functioning. The test involves inserting small needles into muscles to record electrical signals.
- Nerve conduction studies (NCS): Often done alongside EMG, this test measures how well electrical signals move through the nerves to identify nerve damage. It uses surface electrodes to deliver small amounts of electricity and assess nerve function.
- Imaging tests: CT (computed tomography) scan or MRI (magnetic resonance imaging) may be done to rule out other conditions, such as spinal abnormalities or neurological disorders, that could cause similar symptoms.
Remember, each individual's situation is unique. Consult your healthcare professional for personalized advice on examinations, tests, and procedures for diagnosing and determining the stage or severity of polio.
The goals of treatment for polio include:
- Minimizing muscle damage: Physical therapy is recommended to help minimize damage to paralyzed muscles and promote mobility as the acute illness resolves. Therapy aims to improve flexibility, muscle power, and functional stamina.
- Managing symptoms: Treatment focuses on controlling the symptoms of the disease. For mild cases, rest and over-the-counter medicines can help with fever and muscle aches. Pain relievers may be used to manage pain and treat fever.
- Addressing paralysis: Treatment for paralysis depends on the muscles affected. Physical or occupational therapy can assist with arm or leg weakness. The earlier therapy is initiated, the better the outcomes.
- Addressing or preventing complications:
- Measures to prevent urinary tract infections may be necessary if bladder muscles do not contract normally. Intermittent catheterization may be recommended to ensure complete bladder emptying.
- In severe cases where breathing muscles are weakened, a ventilator may be used to assist with breathing.
- Managing post-polio syndrome (PPS): There is no cure for PPS, but treatments can help manage symptoms. Non-fatiguing exercises can improve muscle strength and reduce fatigue. Mobility aids and ventilation equipment may be prescribed based on individual needs.
It's important to note that no specific medications are available to kill the polio virus once an infection has occurred. Treatment primarily focuses on supportive care and symptom management.
Remember, treatment approaches may vary for each individual. Consult with a healthcare professional for personalized advice.
Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Side effects can occur. Check with your health care professional or read the information provided with your medication for side effect information.
