Amazon has confirmed that a number of employees at the company’s logistics site in Coventry, West Midlands, have been diagnosed with tuberculosis (TB). According to the information reported, this involves ten cases of latent TB, which typically means a person is not infectious, but may need treatment to reduce the risk of the infection later developing into active disease.
Working with the UK’s National Health Service (NHS) and the public health body UK Health Security Agency (UKHSA), an expanded screening programme has been carried out and is continuing to identify close contacts and offer testing where appropriate. The situation has also triggered debate about workplace safety, staff communications, and what precautionary measures should apply in a large, high-throughput work environment.
What is known so far
Case numbers and type of TB
- 10 people linked to the site have been identified with latent TB.
- Latent TB typically means the bacteria are present in the body without active illness and without infectiousness in ordinary contact.
- The individuals concerned are reported to be receiving, or to have received, treatment and follow-up.
Public health response: screening and follow-up
- NHS has carried out targeted screening for people who may have had closer contact with those affected.
- UKHSA has been monitoring the situation, conducting a risk assessment, and providing guidance on infection control and follow-up.
Operations at the site
- The warehouse is reported to have remained operational while screening and follow-up have been underway, which is one of the issues that has fuelled debate.
Timeline: from detection to expanded testing
- September 2025: Cases are identified and linked to the site. Public health follow-up begins.
- Autumn/Winter 2025: Screening is targeted at relevant groups to identify additional latent infections and offer preventive treatment.
- January 2026: Expanded testing and follow-up continue in cooperation between Amazon, NHS and UKHSA.
What is tuberculosis, and what does “latent” mean?
Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. It can affect several organs, but is best known for pulmonary (lung) TB. The key distinction in this story is between latent and active TB.
Latent TB (inactive infection)
- Most people have no symptoms.
- The infection is generally not infectious.
- Preventive treatment may be offered to reduce the risk of latent TB becoming active later.
Active TB (disease)
- People can develop symptoms and become clearly unwell.
- If TB is in the lungs, it can be infectious, especially when coughing.
- It requires medical assessment and antibiotic treatment, and may involve public health measures such as contact tracing.
Finding latent TB in a large group does not automatically mean there is an ongoing infectious outbreak at the workplace, but it is often a trigger for broader screening and preventive action.
Symptoms often associated with active TB
Symptoms can vary, but commonly cited signs of active TB include:
- a persistent cough
- fever
- night sweats
- fatigue
- weight loss
These symptoms are non-specific and can be caused by many other conditions. Anyone concerned should follow local health advice and seek medical assessment.
Why would screening take place at a workplace?
When multiple cases are detected in a large work setting, the public health approach can include:
- identifying people who may have had close contact,
- offering testing to detect latent TB,
- providing preventive treatment and follow-up,
- communicating clearly to reduce anxiety and improve participation in testing.
In practice, on-site screening can lower barriers and make it easier for staff to get tested, especially where shift work and a large workforce make individual appointments harder to coordinate.
Union criticism: calls for clarity and stronger protections
The situation has also prompted workplace and safety concerns. Union voices have questioned:
- whether information to staff was sufficiently prompt and clear,
- whether more extensive precautions should have been introduced during the screening period,
- how an employer ensures that everyone—regardless of job role or contract type—has equal access to information, testing, and support.
At its core, the criticism is about trust: in a large workplace, staff want to know exactly what happened, what is being done, and how their health is being protected.
Risk and wider impact: what does this mean for the public?
Based on the information available in the reporting, three points are central:
- Latent TB is generally not infectious, which shapes the risk assessment.
- Screening is a preventive step to identify additional latent infections and reduce the risk of future active TB.
- Ongoing work between the employer and public health bodies focuses on testing, follow-up, and treatment where needed.
For the wider public this typically does not indicate a broad community risk, but the case shows how quickly health protection issues can become a major story when they involve a large workplace and headlines use terms like “outbreak”.
FAQ (for quick scanning)
Is latent TB infectious?
Usually not. Latent TB means the infection is present without active disease, and people are generally not considered infectious.
Why test large numbers if it is “only” latent TB?
To identify additional latent infections and offer treatment so fewer people later develop active TB.
Is the Amazon warehouse closed?
The site is reported to have remained open while screening and follow-up have taken place, which has contributed to debate.
How is TB treated?
TB is typically treated with antibiotics under clinical guidance. For latent TB, this often involves preventive medication and follow-up.
Summary
Amazon has confirmed ten cases of latent tuberculosis linked to a warehouse in Coventry. NHS and UKHSA have carried out and continue to run screening and follow-up to identify close contacts and offer testing, treatment, and monitoring where appropriate. The situation has also raised workplace safety concerns and union criticism, particularly around communications and what precautions should apply in a large, high-density work setting.
