The global community is currently grappling with the most severe outbreak of avian influenza, commonly referred to as bird flu, it has ever faced. However, the impact of this outbreak extends beyond just avian species, as certain mammals are also susceptible to infection.
The virus spreads over extensive distances during the seasonal migration of wild waterfowl. These migratory birds serve as carriers of the virus, and through their droppings, saliva, or through contamination of feed and water sources, they can swiftly transmit the infection to entire flocks of domestic birds within a matter of days.
Initially, wild birds carried a less harmful form of avian influenza known as low pathogenic avian influenza. However, in recent years, this situation has evolved, leading to the emergence of highly pathogenic avian influenza infections in wild birds throughout the entire year. This disturbing development is a cause for serious concern.

Cleaning and disinfection is the first line of defence: how to make the right choice? For successful cleaning and disinfection, various aspects need to be carefully considered: Why is it so important to use a validated biocide? And what properties should a biocide possess to be effective under practical circumstances?

As professor in Farm Animal Health Arjan chairs a group that teaches veterinary medicine and herd health in farm animals. His research is focused at epidemiology of infections in farm animals with the aim to unravel the mechanisms that determine the distribution of infections in animal populations and establish the effectiveness of control measures. To accomplish this goal his group uses experimental, observational as well as modeling studies. Most of the research has been done in close collaboration with scientists studying the infection process at the individual level, because Arjan strongly believe that this helps understanding observations done at the population level. During his career he has studied epizootic, zoonotic as well as endemic diseases and the population dynamics of antibacterial resistance.

Enhancing biosecurity measures and vaccination are crucial steps in preventing the spread of the disease and protecting the flock from the deadly and infectious disease. Vaccination against A.I. has proven to be effective when the exact virus strain and clade is known, but it has been known that influenza viruses are extremely variable and even minor changes in their genetic make-up can render a vaccination protocol ineffective. These viruses are also quick to evolve and change their structure very quickly.
For disinfection, the investment into an effective, registered, tried and tested disinfectant is crucial in protecting the flock from A.I.. The disinfectant Intra Multi-Des GA produced by Intracare has been officially registered and tested against Avian Influenza viruses and therefore is recognized as one of the most powerful disinfectants on the market. Studies for registration by the European Chemicals Agency (ECHA) as well as the Dutch and English relevant biocide authorities encompass strict environmental conditions for the testing of a disinfectant to ensure that the disinfectant is effective in all practical situations.
