The WHO has declared a public health emergency of international concern due to the rapid spread of a new strain of the pox virus in the Democratic Republic of the Congo and neighboring African countries. While the risk outside these regions remains moderate, some countries have begun screening travelers and ships from affected areas. Ship operators are advised to stay informed about port entry requirements and ensure crew members know about symptoms, transmission, and prevention measures. Vaccination is recommended only for those at risk of exposure, reports Grad.
The new strain
On 14 August 2024, the World Health Organization (WHO) declared the pox (monkeypox) outbreak in parts of Africa a public health emergency of international concern (PHEIC) for the second time in two years. This decision highlights the rapid spread of a new pox strain in the Democratic Republic of the Congo (DRC) and neighboring countries, with concerns that this strain may cause more severe illness or higher mortality rates than the previous global outbreak in 2022. Despite these developments, the WHO emphasizes that pox is not comparable to Covid-19, and the risk to the general public outside the DRC and neighboring countries remains moderate.
According to the WHO’s latest situation report, only a few African countries beyond the DRC have reported cases of the newpox strain. Outside of Africa, reported cases are low and mostly linked to individuals with travel histories to affected regions. Nonetheless, the situation could evolve rapidly, and ship operators are urged to stay alert to updates and monitor the outbreak’s progression.
Although the WHO advises against travel restrictions specific to pox, including entry or exit screening and vaccination requirements, some port authorities in countries like Singapore, India, and Argentina have started implementing stricter health measures. To avoid unnecessary delays during port entry or crew changes, ship operators should regularly consult local sources, such as vessel agents, for the latest information on travel and port entry requirements.
For ship personnel, it is crucial to maintain awareness of pox through risk communication, including posters, videos, and message boards. Key messages should cover:
- Symptoms: Mpox typically presents with a rash lasting two to four weeks, possibly accompanied by fever, headache, muscle aches, back pain, low energy, and swollen lymph nodes. The rash, which resembles blisters, can appear on the face, hands, feet, groin, and other areas.
- Transmission: The virus spreads through direct contact with infectious rashes, respiratory secretions during close contact, and contaminated objects. It can also spread from infected animals through bites or consumption of infected meat.
- Prevention: Personal hygiene and avoiding close contact with symptomatic individuals are essential. The WHO recommends vaccination only for those at high risk of exposure.
Ship crews should be encouraged to report any rash-like symptoms immediately and remain isolated if infected. Staying informed and vigilant is key to preventing the spread of pox in maritime settings.
