Leptospirosis is a perplexing conundrum for many. In the existing literature, the pathophysiological mechanisms pertaining to leptospirosis is still not understood in full. Considered as a neglected tropical zoonotic disease, leptospirosis is culmin...ating as a serious problem worldwide, seemingly existing as co-infections with various other unrelated diseases, including dengue and malaria. Misdiagnosis is also common as non-specific symptoms are documented extensively in the literature. This can easily lead to death, as the severe form of leptospirosis (Weil’s disease) manifests as a complex of systemic complications, especially renal failure. The virulence of Leptospira sp. is usually attributed to the outer membrane proteins, including LipL32. With an armament of virulence factors at their disposal, their ability to easily adhere, invade and replicate within cells calls for a swift refinement in research progress to establish their exact pathophysiological framework. As an effort to reconstitute the current knowledge on leptospirosis, the basis of leptospiral infection, including its risk factors, classification, morphology, transmission, pathogenesis, co-infections and clinical manifestations are highlighted in this review. The various diagnostic techniques are also outlined with emphasis on their respective pros and cons.

In Kenya, the bacterial infections that contribute most to human disease are often those in which re-‐sistance is most evident. Exampl...es are multidrug-‐resistant enteric bacterial pathogens such as typhoid, diarrhoeagenic Escherichia coli and invasive non-‐typhi salmonella, penicillin-‐resistant Streptococcus pneu-‐moniae, vancomycin-‐resistant enterococci, methicillin-‐resistant Staphylococcus aureus and multidrug-‐re-‐sistant Mycobacterium tuberculosis. Resistance to medicines commonly used to treat malaria is of particu-‐lar concern, as is the emerging resistance to anti-‐HIV drugs. Often, more expensive medicines are required to treat these infections, and this becomes a major challenge in resource-‐poor settings.

Background: The human helminth infections include ascariasis, trichuriasis, hookworm infections, schistosomiasis, lymphatic filariasis (LF) and onchocerciasis. It is estimated that almost 2 billion ...people worldwide are infected with helminths. Whilst the WHO treatment guidelines for helminth infections are mostly aimed at controlling morbidity, there has been a recent shift with some countries moving towards goals of disease elimination through mass drug administration, especially for LF and onchocerciasis. However, as prevalence is driven lower, treating entire populations may no longer be the most efficient or cost-effective strategy. Instead, it may be beneficial to identify individuals or demographic groups who are persistently infected, often termed as being “predisposed” to infection, and target treatment at them.
Methods: The authors searched Embase, MEDLINE, Global Health, and Web of Science for all English language, humanbased papers investigating predisposition to helminth infections published up to October 31st, 2017. The varying definitions used to describe predisposition, and the statistical tests used to determine its presence, are summarised. Evidence for predisposition is presented, stratified by helminth species, and risk factors for predisposition to infection are identified and discussed.
Results: In total, 43 papers were identified, summarising results from 34 different studies in 23 countries. Consistent evidence of predisposition to infection with certain species of human helminth was identified. Children were regularly found to experience greater predisposition to Ascaris lumbricoides, Schistosoma mansoni and S. haematobium than adults. Females were found to be more predisposed to A. lumbricoides infection than were males. Household clustering of infection was identified for A. lumbricoides, T. trichiura and S. japonicum. Ascaris lumbricoides and T. trichiura also showed evidence of familial predisposition. Whilst strong evidence for predisposition to hookworm infection was identified, findings with regards to which groups were affected were considerably more varied than for other helminth species.
Conclusion: This review has found consistent evidence of predisposition to heavy (and light) infection for certain human helminth species. However, further research is needed to identify reasons for the reported differences between demographic groups. Molecular epidemiological methods associated with whole genome sequencing to determine ‘who infects whom’ may shed more light on the factors generating predisposition.

Neglected tropical diseases (NTDs) is an umbrella term for a diverse group of debilitating infections that represent the most common afflictions for 2.7 billion people living on less than US$2 per d...ay. Major efforts have recently re-focused attention on NTDs, including structured advocacy by the Bill and Melinda Gates Foundation, technical and political support by WHO and large-scale drug donation programs by pharmaceutical companies. An analysis of the Official Development Assistance (ODA) for NTDs in 2009 showed that Development Assistance Committee members and multilateral donors had largely ignored funding NTD control projects. This study reviews the changes since 2009 and finds an increased engagement by pharmaceutical manufacturers through drug donation programs substantially increased by the ‘London Declaration’ in 2012, a focused effort of 77 public and private partners on control or elimination of the 10 most common NTDs, but no increase in ODA for NTDs between 2008 and 2012. The allocation of ODA still does not reflect the respective importance of these diseases.

Fascioliasis is an animal parasitic disease (in cattle and sheep, but also pigs, donkeys, Llamas and alpacas that can be transmitted to humans. The infection is caught when aquatic or semi-aquatic p...lants with the larvae of the worm attached to their stem or leaves are ingested raw or poorly cooked. Once in the human body, the worm lodges itself in the main bile ducts and is responsible for severe morbidity. Endemic areas are distributed globally, but some of the most affected communities are found in the Andean highlands of South America. Triclabendazole is the only drug recommended for prevention and treatment and is provided free-of-charge to endemic countries through WHO. It can be distributed in mass interventions when clusters of cases are detected.

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 operational 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.

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 interventions. 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.

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.
