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 Poli O mean in medical terms?
Polio: Abbreviation for poliomyelitis, an acute and sometimes devastating disease caused by a virus.
How did you get polio?
How do you get polio? You can become infected with the polio virus if you come into contact with the poo (faeces) of someone with the infection, or with the droplets launched into the air when they cough or sneeze. You can also get the infection from food or water that’s been contaminated with infected poo or droplets.
What is polio called now?
The condition is called acute flaccid myelitis, or AFM. With over 300 reports of AFM from this year alone (158 confirmed cases as of Dec 14), the Center for Disease Control and Prevention (CDC) has recently launched an AFM Task Force to investigate this very serious disease.
What type of virus is poliovirus?
Poliovirus, a nonenveloped, positive-sense, single-stranded RNA virus, is a member of the Enterovirus genus within the family Picornaviridae.
What is a surgical puncture to remove fluid from the abdomen?
Paracentesis, or abdominal tapping, is a procedure to remove excess fluid from the area between the abdominal wall and the spine. This area is known as the abdominal cavity. Excess fluid in the abdomen is called ascites.
What color is Poli O?
Poli/o is the word root and combining form for the color gray. This word part is often used to describe the gray matter of the brain and spinal cord.
What animal did polio come from?
The discovery by Karl Landsteiner and Erwin Popper in 1908 that polio was caused by a virus, a discovery made by inoculating macaque monkeys with an extract of nervous tissue from polio victims that was shown to be free of other infectious agents.
Is polio a virus or bacteria?
Polio is a viral disease which may affect the spinal cord causing muscle weakness and paralysis. The polio virus enters the body through the mouth, usually from hands contaminated with the stool of an infected person.
What are the 3 types of polio?
There are three wild types of poliovirus (WPV) – type 1, type 2, and type 3. People need to be protected against all three types of the virus in order to prevent polio disease and the polio vaccination is the best protection.
Is smallpox RNA or DNA?
Smallpox is a double-stranded, 135- to 375-kilobase (kb) DNA virus that replicates in the cytoplasm of the host cell and forms B-type inclusion bodies (Guarnieri bodies). This is in contrast to herpes viruses, which replicate in the nucleus. The orthopoxviruses are among the largest and most complex of all viruses.
Is poliovirus RNA or DNA?
Poliovirus, the prototypical picornavirus and causative agent of poliomyelitis, is a nonenveloped virus with a single-stranded RNA genome of positive polarity. The virion consists of an icosahedral protein shell, composed of four capsid proteins (VP1, VP2, VP3, and VP4), which encapsidates the RNA genome (1).
Is Covid an RNA virus?
COVID-19, short for “coronavirus disease 2019,” is caused by the novel coronavirus SARS-CoV-2. Like many other viruses, SARS-CoV-2 is an RNA virus. This means that, unlike in humans and other mammals, the genetic material for SARS-CoV-2 is encoded in ribonucleic acid (RNA).
Is Covid an airborne virus?
Spread of COVID-19 occurs via airborne particles and droplets. People who are infected with COVID can release particles and droplets of respiratory fluids that contain the SARS CoV-2 virus into the air when they exhale (e.g., quiet breathing, speaking, singing, exercise, coughing, sneezing).
What is the life cycle of COVID-19 virus?
Overall, it is now understood that acute COVID-19 is a two-phase disease, including (a) infection and spreading of the virus mainly in the respiratory and gastrointestinal tracts, and, (b) ARDS (which can occur after a temporal improvement) and the uncontrolled immune response of the host  which can then lead to …
Coronaviruses are a type of virus. There are many different kinds, and some cause disease. A coronavirus identified in 2019, SARS-CoV-2, has caused a pandemic of respiratory illness, called COVID-19.
How long does Covid virus stay in body?
But, it can take several more days for a person’s immune system to actually clear the virus from the body. “Most studies show that by the end of 10 days of infection, your body has cleared the active virus,” says Dr.
How long does COVID-19 last in the body?
How long COVID-19 stays in the body varies from person to person. Generally, people are no longer contagious about 10 days after the onset of symptoms. A recent study found that people can be shed the virus for as long as 83 days, underscoring the importance of frequent testing, quarantining, and isolation practices.
How long is Covid positive after recovery?
Recovered patients: Patients who have recovered from COVID-19 can continue to have detectable SARS-CoV-2 RNA in upper respiratory specimens for up to 3 months after illness onset. However, replication-competent virus has not been reliably recovered from such patients, and they are not likely infectious.
What if I still have Covid symptoms after 10 days?
After 10 days you do not need to self-isolate if you just have a cough. A cough can last for several weeks once the infection has gone. If you continue to feel unwell, and you have not already sought medical advice, you should contact your GP or GP out-of-hours for advice.
Are you immune to Covid after you have it?
A mild case of an illness may not result in strong natural immunity. New studies show that natural immunity to the coronavirus weakens (wanes) over time, and does so faster than immunity provided by COVID-19 vaccination.
Are you contagious after 7 days of Covid?
In high-risk settings, they may be considered infectious from 72 hours before symptoms start. People with mild illness are generally considered to be recovered after 7 days if they have been asymptomatic or have not developed any new symptoms during this time.
What are the symptoms of long Covid?
Some people with long COVID may have symptoms of postural tachycardia syndrome (PoTS) which may need further investigation.
Managing your symptoms
- muscle and joint pain.
- sleep problems.
- loss of smell or taste.
- low mood and depression.
Can I get Covid again?
Reinfection with the virus that causes COVID-19 means a person was infected, recovered, and then later became infected again. After recovering from COVID-19, most individuals will have some protection from repeat infections. However, reinfections do occur after COVID-19.
On average, symptoms showed up in the newly infected person about 5.6 days after contact. Rarely, symptoms appeared as soon as 2 days after exposure. Most people with symptoms had them by day 12. And most of the other ill people were sick by day 14.
Can you have the coronavirus without a fever? Yes. A fever is one of the common symptoms of COVID-19, but you can be infected with the coronavirus and have a cough or other symptoms with no fever, or a very low-grade one — especially in the first few days.
What are the 5 symptoms of COVID?
What are the symptoms of COVID-19 if you’re unvaccinated?
- Sore Throat.
