The disease was first described by Jacob Hain in 1840.
00:00:08
Then, in the 20th century, two types of infections were established.
00:00:13
One didn't affect to the central nervous system and the other one could lead to paralysis.
00:00:18
It began to be controlled in 1949, when Edward Salk developed a batting for the polio.
00:00:24
In 1964, a new and better batting substituted Salk's one.
00:00:31
This one was developed by Albert Sabin.
00:00:36
In 2002, the World Health Organization declared Europe free of the bacterium.
00:00:40
The World Health Organization began its campaign against the polio in 1988.
00:00:46
In 2006, being Niger and Egypt deleted from the infected countries, the WHO declared that
00:00:52
just four countries were still infected by the disease.
00:00:59
Human centers involved on the cure announced that they were going to redouble their efforts
00:01:03
so that there won't be more cases in two years.
00:01:08
The polio is an infection caused by a member of the enterovirus genus.
00:01:11
This group of ARN viruses just causes effect in human beings.
00:01:16
Three stereotypes have been identified.
00:01:22
They all produce the same symptoms, but the PV1 is the most common.
00:01:25
The incubation period can last between 2 and 20 days.
00:01:30
It's transmitted through contaminated water or food.
00:01:35
It's more harmful between the 10 first days, but the transmission is always possible while
00:01:39
it remains in the saliva or excrements.
00:01:44
The virus reaches the body through the mouth and reproduces until it's absorbed by the
00:01:48
blood.
00:01:53
This leads to an extreme expansion through all the body.
00:01:54
It is uncommon that the central nervous system becomes infected and if it is the case it
00:01:58
might be an accidental desviation.
00:02:03
The ways of reaching the CNS are unknown but it depends on the age and gender of the person.
00:02:06
The prognosis consists of three different types.
00:02:14
The first one is amortization polymyelitis.
00:02:17
This prognosis consequences means that the patient is getting better.
00:02:21
The second one is pre-paralyzed poliomyelitis.
00:02:26
This one is not very common, although it affects the central nervous system.
00:02:29
The third one is paralyzed poliomyelitis.
00:02:34
Its symptoms are fever and muscular pain.
00:02:37
There is no cure for polio actually, so the treatment is very simple.
00:02:41
It consists of long rehabilitation terms, physical therapy or orthopedic surgery.
00:02:46
A laboratory diagnosis is usually made based on the recovery of poliovirus.
00:02:52
It is important to determine the source of virus because for each reported cause of paralytic polio caused by wild poliovirus,
00:02:58
an estimated of 200 to 300 other contagious asymptomatic caries exist.
00:03:08
We can prevent this illness by two ways.
00:03:18
Basic immunization is 80% effective.
00:03:22
It reduces the severity of disease.
00:03:26
Vaccine.
00:03:29
There are two types.
00:03:30
The combat polio.
00:03:32
Sal vaccine consists of two doses.
00:03:33
It is effective in about 90% of the patients.
00:03:36
Savings oral polio vaccine consists of one dose which reduces immunity.
00:03:42
Its exit is higher than the 95%.
00:03:48
Thank you.
