       How to prepare for Travel Medicine post-Covid

"We are all aware of that the impact of Covid infections has had on travel and continues to do. With the advent of vaccination programs and sophisticated testing and recording systems in place travel is starting to increase.

However the types of travel such as short haul continues to expand according to the determination of national governments whilst long haul remains dormant. The traveller groups have changed and the emphasis on routine vaccinations being sought by first time travellers going to exotic destinations has shifted to business and essential workers.

With this in mind the marketing of any specific travel medicine services will need to understand these changes. Following lockdowns and extended restrictions many travellers are now attempting to visit families and friends (VFRs) who they have only seen through video links. These VFRs will be a key target group during the revival of travel medicine demands and services.

A key part of the practitioners will be the flexibility to react to short time departures and supply necessary vaccines and medication where required. This parallels with the quick turn around that Covid tests are required for entry into another country before departure from the UK. It seems that a mix of PCR and rapid antigen tests are required within a range of departure times from 24 to 96 hours before departure.

The underlying point here is that this increased cost needs to be allowed for during any travel consultation and also the returning costs of testing and/or isolation. It is unlikely that these costs will be removed in the short term and certainly Covid will become another disease to be routinely covered during a travel medicine risk assessment."

WHO- Neglected Tropical Diseases

Posted on February 4, 2020 at 8:10 AM


In the current climate a lot of attention is focussing on the recent coronavirus outbreak form Wuhan, China. Whereas the global community is focussing on the rapid change necessary to control the spread of this infection, there is a need to retain the wider view of Neglected Tropical Diseases (NTD).

 

In January the WHO day for NTD went un-noticed by a lot of the media; however the 20 plus listed diseases/conditions remain a greater threat to the global community than the coronavirus outbreak.

 

The current NTD list covers infections that include:

Bacteria- trachoma, leprosy, Burundi ulcer,

Helminths- hookworm, ascariasis, filariasis, schistosomiasis, taeniasis

Protozoa- leishmaniasis, trypansomiasis

Viruses- dengue, chikungunya

Snake bite envenomation

 

It is estimated that 10% of the global population are suffering from one of the above infections and the all are in countries below the World Bank poverty line ($1.90/day).

 

These infections require substantial a international investment before eradication. The Gates Foundation has placed over $300million into a reduction of some of these and currently we are approaching the elimination of trypansomiasis in Africa and leishmaniasis on the Indian sub-continent.

 

Moving forward is the need to consider that financial investment into vaccines is the only method for reduction and final elimination. It is becoming evident of the need to combine other disease reduction streams such as the issuing of insect prevention bed nets and improved education on sanitation, washing and hygiene. These are supported by many other agencies who tackle the principles of adjusting the local cultures and beliefs to improve their own communities. Fundamental to these changes are the wish of the local communities to want to change; management of the change involving adjustments to existing cultures and the correct utilisation of products issued for disease reduction and control (eg bed nets).

 

Whilst the funding streams remain fragile due to economic pressures then the delivery of vaccines and chemotherapy will continue to suffer. Therefore a combined funded strategy has a place within the strategy for sustained delivery and progress in making changes utilising a global health pathway.
