The recent spike in measles cases in England has prompted the declaration of a national incident by the UK Health Security Agency (UKHSA) with confirmed cases rising to the highest level since the mid-1990s in the West Midlands. There have been 133 cases since 1 October in the region, with a further 96 “likely” cases, according to the UK Health Services Authority (UKHSA). The health agency has started a campaign to encourage uptake of the measles, mumps and rubella vaccine in England as over 3.4 million children in the nation have not been vaccinated against the virus. Further outbreaks could occur in the West Midlands and other parts of England if vaccination rates do not increase.

In view of what is now a national incident, this short article will outline how you can safely transport measles test samples between healthcare facilities and testing centres using Intelsius packaging and labels.

What is the relevant compliance to adhere to?

Measles is a highly infectious virus that can cause great risk to infants, young children, pregnant women or immunocompromised individuals. This is why it is extremely important to adhere to international regulations on the transport of these samples across the country.

The classification of infectious substances are as follows:

Category B substances, known as UN3373 covers substances which are not appropriate for inclusion in Category A.

Category A is described as an infectious substance that, if exposed to it, is life threatening or capable of causing permanent disability in otherwise healthy humans or animals. It is further sub-divided into two sub-categories: UN2814 (affecting humans) and UN2900 (affecting animals only).

We’ve outlined the difference between Category A and B compliance here, along with the relevant transport regulations and packaging requirements.

Oral samples are usually taken for a suspected measles cases and while there is no official guidance published in the UK on the transport of measles samples, Intelsius has a range of packaging solutions which are both Category A and Category B compliant, as well as compliant with other international transport regulations.
