poliovirus

At the beginning of 2006 we are now looking at the lowest number of countries with indigenous poliovirus ever in history - four countries.

Countries should also address any gaps in polio immunization coverage to minimise the consequences of a poliovirus introduction.

The poliovirus can easily be imported into a polio-free country and can spread rapidly amongst unimmunized populations.

A: Oral polio vaccine (OPV) contains a weakened version of poliovirus, activating an immune response in the body.

The oral polio vaccine contains a weakened version of poliovirus, activating an immune response in the body.

As China, Congo, the Russian Federation and Tajikistan have learned, the poliovirus does not respect national borders.

When this virus regains the ability to circulate, it is called a circulating vaccine-derived poliovirus (cVDPV).

By eradication, WHO, the Global Commission on Certification, and Rotary mean the interruption of the transmission of the wild poliovirus .

This year, Somalia is celebrating three years of being polio-free, with no cases of wild poliovirus in Somalia since 25 March 2007.

Presumably poliovirus was incorporated into the resistant cells during the fusion process.

The primary challenge to polio eradication is the ongoing transmission of the poliovirus in the remaining endemic countries.

Genetic sequencing has determined that the cases are caused by a poliovirus most closely related to that circulating in neighbouring Angola.

targeted "mop-up" campaigns once wild poliovirus transmission is limited to a specific focal area.

In places where fragile governments cannot assist us and health infrastructure is nonexistent, fighting the poliovirus is costly.

Prior to these cases, wild poliovirus has not been found in Yemen since AFP surveillance commenced in 1996.

This new phase was announced alongside the confirmation that indigenous poliovirus has not circulated in Egypt and Niger for over 12 months.

In September, WHO received confirmation that the most dangerous strain of poliovirus has spread from Pakistan to China.

As with other infectious diseases, the poliovirus does not respect borders.

Vaccine campaigns, which have not been implemented as required, have lead to the re-emergence of yellow fever virus and poliovirus.

The findings of the investigation suggest a recent introduction of wild poliovirus.

The last wild poliovirus reported in Egypt was found in an environmental sample on 13 January 2005.

Again, this tells us that endemic transmission of the poliovirus anywhere in the world threatens the world everywhere.

32 of these cases are confirmed wild poliovirus type 1, results are pending for the remaining cases.

Four cases have been confirmed to have been caused by wild poliovirus type 1 and laboratory testing continues.

The first is the need for confirmation that the poliovirus is not being transmitted anywhere in the world.

Historically, Chad has been associated with further international spread of poliovirus.

Two cases have been confirmed to have been caused by wild poliovirus type 1 and laboratory testing continues.

A fully-immunized population will be protected from all strains of poliovirus, whether wild or vaccine-derived.

The world embarked that year on a programme to eradicate the poliovirus, which cripples permanently.

This means by the time a paralytic case is found, the poliovirus has probably spread.

Genetic sequencing has now determined that the poliovirus is most closely related to virus from Uttar Pradesh, India.

National health authorities are planning a response to an outbreak of wild poliovirus in Namibia, polio-free since 1996.

Objective: To evaluate the effect of poliovirus vaccine supplemental immunization.

Poliovirus has a habit of finding pockets of inadequately vaccinated children.

This represents the first importation of poliovirus in the WHO European Region since it was certified polio-free in 2002.

Poliovirus in smallest area ever: only 4 countries remain that have never stopped polio before.

The poliovirus causing the outbreak originated in northern India.

Stopping wild poliovirus transmission in endemic countries: Polio today is more geographically restricted than ever before.

Monovalent oral poliovirus type 1 vaccine will be used to quickly build immunity levels among children in the country.

Poliovirus type 1 has been detected in diagnostic samples from cases of Acute Flaccid Paralysis (AFP) from Tajikistan.

To date, poliovirus type 1 has been isolated in diagnostic specimens from 7 of these cases.

Poliovirus transmission remained a public health challenge in western Uttar Pradesh, India in late 2005 and early 2006.

In 2011, the WHO Western Pacific Region also suffered an importation of poliovirus.

In 2005, poliovirus of Indian origin re-infected Angola, before subsequently spreading to the Democratic Republic of the Congo in 2006.

T1 phage displayed a higher survival than poliovirus.

Knowledge of the poliovirus has expanded with aggressive research carried out under the eradication effort.

Of the three types of poliovirus, type 2 has been eliminated since 1999 and type 3 is limited to three areas of focal transmission.

Type-2 poliovirus has been eliminated.

In 2009, Tajikistan reported 35 cases of acute flaccid paralysis, of which none were caused by wild poliovirus.

Wild poliovirus type 1 (WPV1) genetically linked to virus currently circulating in Pakistan has been isolated in China.

Globally, more than 90, 000 cases of acute flaccid paralysis were reported in 2009, of which 1606 were caused by wild poliovirus.

there are at least three years of zero polio cases due to wild poliovirus;

To stop transmission of the wild poliovirus and optimize the benefits of polio eradication, the global priorities are
