From the Guidelines
The current diagnostic, monitoring, prophylactic, and therapeutic strategies for zoonotic diseases prioritize a One Health approach, integrating human, animal, and environmental health sectors for comprehensive disease management, as highlighted in recent studies 1. The findings reveal improved diagnostic techniques including rapid molecular tests, next-generation sequencing, and point-of-care testing that enable faster detection of zoonotic pathogens. Some key points to consider in the management of zoonotic diseases include:
- Advanced surveillance systems that incorporate digital platforms and artificial intelligence for real-time monitoring of disease spread
- Prophylactic measures that have expanded with new vaccines for diseases like rabies and brucellosis
- Therapeutic approaches that now include targeted antimicrobials, immunotherapies, and antiviral medications specific to zoonotic infections
- The importance of climate change as a significant factor influencing the emergence and spread of zoonotic diseases by altering vector habitats and animal migration patterns
- The need for careful stewardship of medications in both human and veterinary medicine to preserve treatment efficacy for these cross-species infections, as noted in 1.
In terms of specific strategies, the use of preexposure and postexposure prophylaxis, as recommended by the Advisory Committee on Immunization Practices (ACIP), is crucial in preventing rabies and other zoonotic diseases, as outlined in 1 and 1. Additionally, the control of rabies among wildlife reservoirs is difficult, but vaccination of free-ranging wildlife or selective population reduction might be useful in some situations, as discussed in 1. Overall, the management of zoonotic diseases requires a comprehensive and integrated approach that takes into account the complex interactions between human, animal, and environmental health sectors.
From the FDA Drug Label
Treatment: Doxycycline is indicated for the treatment of the following infections: Rocky Mountain spotted fever, typhus fever and the typhus group, Q fever, rickettsialpox, and tick fevers caused by Rickettsiae. Prophylaxis: Doxycycline is indicated for the prophylaxis of malaria due to Plasmodium falciparum in short-term travelers (<4 months) to areas with chloroquine and/or pyrimethamine-sulfadoxine resistant strains
The current therapeutic strategies for zoonotic diseases include the use of doxycycline for the treatment of:
- Rocky Mountain spotted fever
- Typhus fever
- Q fever
- Rickettsialpox
- Tick fevers
- Plague due to Yersinia pestis
- Tularemia due to Francisella tularensis
- Brucellosis due to Brucella species

- Malaria due to Plasmodium falciparum in short-term travelers to areas with chloroquine and/or pyrimethamine-sulfadoxine resistant strains 2 There is no information in the provided drug label regarding diagnostic or monitoring strategies for zoonotic diseases.
From the Research
Diagnostic Strategies
- There are no specific diagnostic strategies mentioned in the provided studies for zoonotic diseases in general, but for rabies, diagnosis is typically made based on clinical symptoms and laboratory tests 3, 4, 5.
Monitoring Strategies
- Monitoring of zoonotic diseases is crucial for early detection and prevention of outbreaks, but the provided studies do not specifically discuss monitoring strategies for zoonotic diseases in general 6, 7.
- For rabies, monitoring of vaccination coverage and surveillance of animal bites are important for preventing the spread of the disease 3, 4.
Prophylactic Strategies
- Post-exposure prophylaxis (PEP) is a crucial prophylactic strategy for preventing rabies, which includes wound washing, administration of rabies immunoglobulin, and vaccination 3, 4, 5.
- The use of antiviral drugs such as favipiravir has been explored as an alternative to rabies immunoglobulin in PEP regimens for rabies 5.
- Practicing good hygiene and avoiding contact with animals are general prophylactic strategies for preventing the spread of zoonotic diseases 6.
Therapeutic Strategies
- For rabies, therapeutic strategies are limited, and the disease is almost invariably fatal once clinical symptoms appear, but prompt administration of PEP can prevent the disease 3, 4, 5.
- The use of antiviral drugs such as favipiravir has been shown to be effective in treating rabies-infected mice, and clinical trials are warranted to explore its potential as a therapeutic strategy for rabies in humans 5.
- For other zoonotic diseases, therapeutic strategies vary depending on the specific disease, but a One Health approach that recognizes the close link between human, animal, and ecosystem health is essential for controlling zoonoses 7.
