Transmission of many infectious diseases depends on interactions between humans, animals, and the environment. Incorporating these complex processes in transmission dynamic models can help inform policy and disease control int...erventions. We identified 20 diseases involving environmentally persistent pathogens (ie, pathogens that survive for more than 48 h in the environment and can cause subsequent human infections), of which indirect transmission can occur from animals to humans via the environment.

The DCPs are a series of disease specific datasheets that list the critical commodities and the technical specifications for each commodity per disease. The DCPs inform Member States and operational partners of commodity requirements and potential gaps in the health emergency supply chain. From an o...perational readiness perspective, the DCPs provide the basis for a globalized stockpile system, response planning, technical guidance and supply market assessments.
Initially, the DCPs consist of 11 infectious diseases; Ebola virus, Marburg virus, cholera, Lassa fever, pandemic influenza, MERS-COV, SARS, meningococcal meningitis, yellow fever, Shigellosis, and typhoid fever.

The Sierra Leone National Infection Prevention and Control Guidelines were jointly developed and updated by the Ministry of Health and Sanitation in collaboration with the World Health Organization and the US Centers for Disease Control and Prevention.
This project aimed to reduce the risk of vector-borne infection with Chagas disease by
controlling triatomine bugs, the vectors transmitting the parasite of Chagas disease, and
establishing an epidemiological surveillance system with community participation.

Pandemic plans recommend phases of response to an emergent infectious disease (EID) outbreak, and are primarily aimed at preventing and mitigating human-to-human transmission. These plans carry presumptive weight ...and are increasingly being operationalized at the national, regional and international level with the support of the World Health Organization (WHO). The conventional focus of pandemic preparedness for EIDs of zoonotic origin has been on public health and human welfare. However, thisfocus on human populations has resulted in strategically important disciplinary silos. As the risks of zoonotic diseases have implications that reach across many domains outside traditional public health, including anthropological, environmental, and veterinary fora, a more inclusive ecological perspective is paramount for an effective response to future outbreaks.

Yaws is a disfiguring non-venereal disease caused by infection with the spirochaete. Treponema pallidum subspecies pertenue which is closely related to the causative agent of syphilis and those of the other endemic treponematoses, bejel and pinta. The disease is endemic in certain areas of the World... Health Organization (WHO) African, South-East Asia and Western Pacific regions. Of the neglected tropical diseases identified for elimination and eradication, yaws is one of two diseases targeted for eradication. In 1949, the Second World Health Assembly adopted resolution WHA2.36, which addresses yaws, bejel and pinta as major public health problems that need attention.

- The goal of diagnostic testing for Ebola and Marburg virus diseases is to identify cases to provide timely and appropriate care and to stop disease transmission.
- All individuals meeting the case definition for Ebola or Marburg virus diseases should be tested.
- The recommended sample type ...for testing for orthoebolaviruses and orthomarburgviruses is whole blood or plasma for living patients, and oral swab for deceased individuals.
- Laboratory confirmation of Orthoebolavirus and Orthomarburgvirus infections and further species identification should be done using nucleic acid amplification testing (NAAT).
- If a suspected case tests negative (living patient) and the blood was drawn less than 72 hours after symptom onset, a second test should be performed with blood drawn more than 72 hours after symptom onset.
- All manipulations in laboratory settings of samples originating from suspected, probable or confirmed cases of Ebola and Marburg virus diseases should be conducted with appropriate biosafety measures according to a risk-based approach.
- Whole or partial genome sequencing can be used to characterize viruses and complement epidemiologic investigations.
- Member States are strongly encouraged to share genetic sequence data (GSD) in publicly accessible databases.
- Member States are required to immediately notify the World Health Organization (WHO) under the International Health Regulations (IHR) 2005 of positive laboratory results.

Buruli ulcer is a chronic, progressive skin disease caused by infection with Mycobacterium ulcerans. It is currently considered to be one of the neglected tropical diseases; less common than tuberculosis but more common than leprosy. The initial lesion is a painless subcutaneous nodule, usually less... than 5 cm diameter and adherent to skin. The nodule typically breaks down centrally after days to weeks forming an ulcer with undermined edges. Thus, the external appearance of the ulcer underestimates the true size of the affected area. The patient remains well and there is no pain unless secondary bacterial infection occurs. Other forms of M. ulcerans disease include a firm plaque lesions that behaves in the same way as the nodule or an oedematous lesion that is more aggressive and extends rapidly resulting in a very large ulcer.
Any age group can be affected by Buruli ulcer diseases, but the incidence peaks at 5 to 15 years. Ulcers are most frequently on the limbs but can be on the trunk or head, sometimes with catastrophic consequences such as loss of sight or loss of breast or genital tissue. Healing close to a joint can result in contracture, and sometimes there is so much tissue destruction on a limb that amputation is unavoidable. Occasionally osteomyelitis occurs in bone adjacent to a skin lesion but involvement of other organs is rare. Disseminated disease with HIV has been reported.

Considered a neglected tropical disease, Guinea worm disease (dracunculiasis) is a parasitic infection caused by the nematode roundworm parasite Dracunculus medinensis. It is contracted when people consume water from stagnant sources contaminated with Guinea worm larvae. Inside a human's abdomen, Gu...inea worm larvae mate and female worms mature and grow. After about a year of incubation, the female Guinea worm, one meter long, creates an agonizingly painful lesion on the skin and slowly emerges from the body. Guinea worm sufferers may try to seek relief from the burning sensation caused by the emerging worm and immerse their limbs in water sources, but this contact with water stimulates the emerging worm to release its larvae into the water and begin the cycle of infection all over again.

Noncommunicable diseases (NCDs) or Chronic noncommunicable diseases (NCDs) are the 1st cause of death and disability worldwide.
The term NCDs refers to a group of conditions that are not mainly caused by an acute infection, result in long-term health consequences and often create a need for long-...term treatment and care. These five main NCDs are cancers, cardiovascular disease, diabetes, chronic lung illnesses and Mental health conditions.
Many NCDs can be prevented by reducing common risk factors such as tobacco use, harmful alcohol use, physical inactivity and eating unhealthy diets. Many other important conditions are also considered NCDs, including injuries and mental health disorders.

It is estimated that, in Latin America alone, between 6 and 8 million people are infected with the parasite, and 99% of these are not receiving treatment, either because they are unaware of their infection or because they do not know that treatment exists. The potential spread of the disease is also... a cause for considerable concern: 65 million people live in areas of exposure and are at risk of contracting Chagas disease, and 28,000 new cases occur every year.

The Global Health Security Agenda programme develops national capacity to prevent zoonotic and non-zoonotic diseases while quickly and effectively detecting and controlling diseases when they do emerge. The Emerging Pandemic Threats programme improves national capacity to pre-empt the emergence and ...re-emergence of infectious zoonotic disease and to prevent the next pandemic.
Action against emerging pandemic threats is taken through projects on: Avian influenza, Middle East respiratory syndrome, Africa Sustainable Livestock 2050 and Emergency equipment stockpile. With high-impact diseases that jump from animals to humans on the rise, these programmes are reducing the risk to lives and livelihoods from national, regional and global disease spread.
