Available evidence demonstrates that direct patient contact and contact with infectious body fluids are the primary modes for Ebola virus transmission, but this is based on a limited number of studies. In this review, the authors address what we know and what ...we do not know about Ebola virus transmission. They also hypothesize that Ebola viruses have the potential to be respiratory pathogens with primary respiratory spread.

Human African trypanosomiasis (HAT) has been an alarming global public health issue. The disease affects mainly poor and marginalized people in low-resource settings and is caused by two subspecies of haemoflagellate parasite, Trypanosoma brucei and transmitted by tsetse flies. Progress made in HAT ...control during the past decade has prompted increasing global dialogue on its elimination and eradication. The disease is targeted by the World Health Organization (WHO) for elimination as a public health problem by 2020 and to terminate its transmission globally by 2030, along-side other Neglected Tropical Diseases (NTD). Several methods have been used to control tsetse flies and the disease transmitted by them. Old and new tools to control the disease are available with constraints.
Currently, there are no vaccines available. Efforts towards intervention to control the disease over the past decade have seen considerable progress and remarkable success with incidence dropping progressively, reversing the upward trend of reported cases. This gives credence in a real progress in its elimination. This study reviews various control measures, progress and a highlight of control issues, vector and parasite barriers that may have been hindering progress towards its elimination.

Schistosomiasis, also known as bilharzia, is a disease caused by parasitic worms that require two hosts: humans and certain species of snails. There are two forms of the disease, namely, intestinal schistosomiasis, caused by Schistosoma mansoni and S. japonicum, and urogenital schistosomiasis, cause...d by S. haematobium. There are less common schistosome species in some parts of the world, e.g. S. mekongi and S. intercalatum. Schistosomiasis ranks second only to malaria as the most common parasitic disease worldwide.

The international community sits at the tipping pointof a post-‐antibiotic era, where common bacterial infections are no longer treatable with the antibiotic armamentarium that exists. In South Africa, t...he identification of the first case of pan-‐resistant Klebsiella pneumoniae(Brink et al, J Clin Microbiol. 2013;51(1):369-‐72) marks a watershed moment and highlights ourtip of the antibiotic resistance ‘iceberg’ in this country. Multi-‐drug resistant (MDR)-‐bacterial infections, predominantly in Gram-‐negative bacteria such as Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosaand Acinetobacter baumanniiare now commonplace in South African hospitals. Whilst a number of expensive new antibiotics for Gram-‐positive bacterial infections have been manufactured recently (some of which are licenced for usein South Africa), no new antibiotics active against Gram-‐negative infections are expected in the next 10-‐15years. Hence what we have now, needs conserving

Population movements have turned Chagas disease (CD) into a global public health problem. Despite the successful implementation of subregional initiatives to control vectorial and transfusional Trypanosoma cruzi transmission in Latin American settings where t...he disease is endemic, congenital CD (cCD) remains a significant challenge. In countries where the disease is not endemic, vertical transmission plays a key role in CD expansion and is the main focus of its control. Although several health organizations provide general protocols for cCD control, its management in each geopolitical region depends on local authorities, which has resulted in a multitude of approaches. The aims of this review are to (i) describe the current global situation in CD management, with emphasis on congenital infection, and (ii) summarize the spectrum of available strategies, both official and unofficial, for cCD prevention and control in countries of endemicity and nonendemicity. From an economic point of view, the early detection and treatment of cCD are cost-effective. However, in countries where the disease is not endemic, national health policies for cCD control are nonexistent, and official regional protocols are scarce and restricted to Europe. Countries of endemicity have more protocols in place, but the implementation of diagnostic methods is hampered by economic constraints. Moreover, most protocols in both countries where the disease is endemic and those where it is not endemic have yet to incorporate recently developed technologies. The wide methodological diversity in cCD diagnostic algorithms reflects the lack of a consensus. This review may represent a first step toward the development of a common strategy, which will require the collaboration of health organizations, governments, and experts in the field.

Event-based surveillance (EBS) is defined as the organized collection, monitoring, assessment and interpretation of mainly unstructured ad hoc information regarding health events or risks, which may represent an acute risk to health. Both indicator-based and event-based surveillance components serve... the early warning and response (EWAR) function of the public health surveillance system. The Framework for Event-based Surveillance offers guidance to public health practitioners seeking to implement EBS at each administrative level in healthier countries.
