Current Disease Outbreaks

A disease outbreak is a sudden and unexpected increase of cases of a particular disease. The time that the disease lasts can vary and it can cover a small community or several countries. 

Below are some of the most recent disease outbreaks from around the world.


1. Streptococcus A (Strep A)

Affected Areas: 

England, Scotland, and Northern Ireland.


The first recent reported case of Invasive Group A Streptococcus (iGAS) was in late November, 2022. The infected was a child aged below 10. Then, as of Saturday, the 10th of December, 2022, iGAS had caused 16 deaths. 


The symptoms of Strep A include swollen glands, fever, sandpaper-like rash, sore throat, scarlet fever, and pain when swallowing.

The symptoms of iGAS, which is a severe form of Strep A, include high fever, severe muscle aches, vomiting, diarrhoea, localised body pain, redness around a wound, and toxic shock syndrome.

Strep A can cause other conditions, such as Impetigo (a contagious skin infection) and Pneumonia (inflamed air sacs in both lungs).

How do people catch Streptococcus A (Strep A)? 

Strep A bacteria is often present in a person’s throat or nose. It can be spread through coughing, sneezing, or if someone has direct contact with the bodily fluids of an infected person.

Some people may carry Strep A bacteria without having any symptoms, but they can still spread the bacteria on to others.  

Severe Strep A (iGAS) occurs when bacteria gets into the blood, muscles, and lungs, which can cause the infected person to experience toxic shock syndrome.

2. Polio

Affected Areas:

New York and London.


These details are sparse at the moment as the outbreaks are recent. This is the data we currently have:

New York:

1 case was confirmed in July 2022, after an unvaccinated adult developed paralysis. Hundreds more are thought to have caught Polio from this one case. 


No cases as of yet. Polio has been found in sewers 116 times through water testing since February 2022.


Detection of Polio in the sewers outside of both cities.

In London, all children aged 1 to 9 are to be offered a dose of the Polio vaccine in response to the outbreak.

How do people catch Polio?

The virus enters through the mouth, normally from hands infected with the stool of someone who has Polio.

Is there a vaccine for Polio?

Yes, there is a vaccination for Polio. You can book an appointment through The Travel Health Clinic to protect yourself against this disease.
