Acute poliomyelitis is a notifiable disease. Although natural polio infection has been eliminated from the UK for many years, there is still the potential for acute cases to present in the UK, acquired in endemic areas.

Consider the possibility of post-polio syndrome (PPS) in patients who may have been infected during childhood and are showing unexplained signs of fatigue and weakness. Patients may or may not be aware that they have had polio.

Background

Acute poliomyelitis

Poliomyelitis is an acute viral infection that can:

• affect the central nervous system
• lead to paralysis

are at greatest risk of infection.

Since the launch of the in 1988:

• more than against polio
• reported cases have

In the UK, the last case of domestically acquired polio infection was in 1984. All cases since then have been acquired abroad.

Global polio cases are .

Post-polio syndrome

In the UK, out of an estimated 120,000 people who have been previously affected by polio, , a neurological condition which can severely limit normal activities of daily living.

Transmission

The polio virus is spread via:

• person-to-person contact with infected secretions from the nose or mouth
• infected faeces

After initial infection, the virus is shed intermittently in faeces for several weeks, which can cause rapid spread throughout communities, especially in areas with .

On rare occasions, live polio vaccines can mutate to a virulent form that can cause paralytic disease in recipients or their contacts.

Symptoms

Acute poliomyelitis

Most people infected with poliovirus . When symptoms do develop, they .

:

• fever
• fatigue
• headache
• vomiting
• stiffness in the neck
• pain in the limbs

(usually in the legs), and of these cases .

Post-polio syndrome

Following a period of years of stability, people :

• onset of new weakness or abnormal fatigue in previously affected or unaffected muscles
• general decrease in stamina
• muscle and/or joint pain
• muscle atrophy
• breathing, sleeping and/or swallowing problems
• cold intolerance

Testing and treatment

Urgently refer patients with suspected acute poliomyelitis to an infectious disease specialist for formal diagnosis and management.

Take appropriate samples for laboratory investigation according to the enteric virus unit.

Local laboratories with queries about testing samples for polio virus should contact the Virus Reference Department at the UK Health Security Agency.

Refer cases of suspected PPS to a neurologist for investigation and management.

PPS may respond to a .

Prevention and control

In the UK, immunisation is used to prevent and control poliomyelitis, so ensure that children and adults are up to date with the UK immunisation schedule. Refer to guidance on vaccination of individuals with uncertain or incomplete immunisation status.

Ask opportunistically about travel plans, as patients who travel to countries where the infection is endemic to visit friends and relatives are at increased risk of acquiring infection.

For country specific travel advice, see .

Acute poliomyelitis is a notifiable disease in the UK. If a case is diagnosed or suspected, you should immediately notify your local health protection team (HPT).
