What really caused polio?
Polio, or poliomyelitis, is a disabling and life-threatening disease caused by the poliovirus.
The virus spreads from person to person and can infect a person’s spinal cord, causing paralysis (can’t move parts of the body)..
What does Polio do to muscles?
When it multiplies in the nervous system, the virus can destroy nerve cells (motor neurons) which activate skeletal muscles. These nerve cells cannot regenerate, and the affected muscles lose their function due to a lack of nervous enervation – a condition known as acute flaccid paralysis (AFP).
How many polio survivors are left?
The World Health Organization estimates that 10 to 20 million polio survivors are alive worldwide, and some estimates suggest that 4 to 8 million of them may get PPS.
How long does Polio take to kill?
People who have milder polio symptoms usually make a full recovery within 1–2 weeks. People whose symptoms are more severe can be weak or paralyzed for life, and some may die. After recovery, a few people might develop “post-polio syndrome” as long as 30–40 years after their initial illness.
What does the polio virus look like?
The viral particle is about 30 nm in diameter with icosahedral symmetry. Because of its short genome and its simple composition—only RNA and a nonenveloped icosahedral protein coat that encapsulates it, poliovirus is widely regarded as the simplest significant virus.
When did they stop giving polio vaccine?
OPV was recommended for use in the United States for almost 40 years, from 1963 until 2000. The results have been miraculous: Polio was eliminated from the United States in 1979 and from the Western Hemisphere in 1991. Since 2000, only IPV is recommended to prevent polio in the United States.
Who is most at risk for polio?
Pregnant women, people with weakened immune systems — such as those who are HIV-positive — and young children are the most susceptible to the poliovirus. If you have not been vaccinated, you can increase your risk of contracting polio when you: travel to an area that has had a recent polio outbreak.
Can polio be passed from mother to child?
No. Post polio syndrome is not inherited .
How does a baby get polio?
The virus often spreads through contact with infected feces (stool). It can be spread when an infected child coughs or sneezes infected droplets into the air. A child is more at risk for polio if he or she is in an area where polio is still active.
Can polio be passed down?
It is caused by infection with the poliovirus which can be spread by direct person-to-person contact, by contact with infected mucus or phlegm from the nose or mouth, or by contact with infected feces. There are three basic patterns of polio infection: subclinical infections, nonparalytic, and paralytic.
How can polio be prevented?
Polio can be prevented by immunizing a child with approrpiate vaccination. There are currently two effective polio vaccines, the inactivated poliovirus vaccine (IPV) and the live attenuated oral polio vaccine (OPV).
How many cases of polio are there in 2019?
To date, there have been 94 wild poliovirus cases reported in 2019, compared to 33 in all of 2018. In addition, several African nations reported single cases of vaccine-derived polio: Chad, Benin, the Democratic Republic of the Congo, Ghana, Ethiopia, Togo, and Zambia.
Can you catch polio twice?
Does past infection with polio make a person immune? There are three types of polio virus. Lifelong immunity usually depends on which type of virus a person contracts. Second attacks are rare and result from infection with a polio virus of a different type than the first attack.
How do you know if you had polio as a child?
Common PPS symptoms include: muscle and joint weakness, fatigue, pain, muscle atrophy, difficulty breathing or swallowing, skeletal deformities, cold intolerance, and temporary interruptions of breathing while sleeping.
How long do polio patients live?
Poliomyelitis (polio) is a serious disease caused by infection with 1 of 3 types of poliovirus. The virus is live for 6 weeks. It is spread via water, food or hands contaminated with the faeces (poo) or throat secretions of someone who is infected with the virus.
What is the sign of polio?
Initial signs and symptoms of paralytic polio, such as fever and headache, often mimic those of nonparalytic polio. Within a week, however, other signs and symptoms appear, including: Loss of reflexes. Severe muscle aches or weakness.
