None die from polio. sorry, not true...many old cases of polio proved to cause paralysis, obviously. But if it spreads to the respiratory muscles, it can, in fact, kill you. This was when the iron lung was designed. I have no idea how many people die each year, but they do.
Many thousands, if not tens of thousands, of people are infected each year by polio, mostly in developing countries, especially India. However, the majority of cases [about 9 in 10] are asymptomatic, or resolve themselves without any symptoms. Paralysis results in fewer than 1% of cases, and thus polio outbreaks are difficult to determine in terms of how many people get infected. In the United States, there is an average of 8-12 polio cases each year, most originating from the live attenuated [weakened] polio vaccine, which occasionally mutates [about one time in six million] into the virulent form.
In 2010 the World Health Organization says only 1,352 cases were reported worldwide. This is going to vary by a few every year, so if you're writing a paper, you might want to round and say something like, "less than 1,500 cases a year."
I don't know! I'm trying to figure it out my self!
you aren't BORN with polio. it's a disease that you catch.
Polio was completely wiped out by the early 60's. Vaccinations completely eradicated the virus.

A polio vaccine was invented in 1954. Each year after that, the number of polio cases decreased. By 1974, only 5 cases occurred. These were all people who were linked to the polio vaccine.
50,000 people died of polio.
700,000
about 5 million each year many people get infected
About 3000 people in the United States are affected each year.
5000
It depends on what part of the nervous system is infected by the polio virus. Though most people recovered quickly from polio, some suffered temporary or permanent paralysis and even death. Many polio survivors were disabled for life. They were a visible, painful reminder to society of the enormous toll this disease took on young lives. In about 95% of all polio cases, the person has no symptoms at all. These are known as asymptomatic cases. The rest of polio cases can be divided into three types: abortive polio, non-paralytic polio, and paralytic polio. Abortive polio: In these cases, polio is a mild illness, with viral-like symptoms such as fever, fatigue, headache, sore throat, nausea, and diarrhea. Non-paralytic polio: These cases typically involve the symptoms of abortive polio, with additional neurological symptoms, such as sensitivity to light and neck stiffness. Paralytic polio: The first signs of paralytic polio, after an initial period of viral-like symptoms, typically begin with loss of superficial reflexes and muscle pain or spasms. Paralysis, usually asymmetric, follows. Fewer than 1%-2% of people who contract polio become paralyzed. In most cases of paralytic polio, the patient recovers completely. However, for a certain number of people, paralysis or muscle weakness remains for life.
How many people are infected with corona virus in Houston
It is estimated the about 500 children got polio in Afghanistan in the year of 2012. More and more children get polio every year. And many people are trying to help the children of Afghanistan.
It is difficult to provide an exact number of people infected with viruses globally each year as it varies depending on the type of virus and region. However, millions of people worldwide are affected by viral infections annually.
About 85% of those people exposed to the virus will become infected with it.
one or two there have been 17 ever infected in usa
