Infection Prevention and Control Programmes
January 2020
In 2007, WHO warned that infectious diseases are emerging and re-emerging at a rate that has not been seen before. The potential for infectious ...an class="attribute-to-highlight medbox">diseases to spread rapidly results in high morbidity and mortality, causing a potential global public health treat of major concern.
Several factors are contributing to the (re)emergence of infectious diseases such as population growth, living in close contact with animals, frequent travelling, poverty, destructive ecological changes due to economic development and land use and climate change result in global warming.
Especially Africa is at a threat for (re)emerging infectious diseases due to the huge population growth (expected to reach 2.5 billion by 2050) with rapid urbanisation. Additionally, people across and beyond the continent are excessively mobile which is combined with a weak health system. Moreover, the risk of (re)emerging infectious disease is further heightened by three newly adopted continental initiatives: African Continental Free Trade Area, Free Movement of Persons and African Passport and Single African Air Transport Market.

Many African countries were amongst the most rapid to respond to the emerging threat of COVID-19, implementing large-scale interventions at very early stages of their epidemic. As demonstrated in this document using very simple models, this rapid mo...bilization and timeliness of implementing control measures is likely to be an important determinant of their success. Indeed, as these measures were relaxed, subsequent waves of disease have been observed in many countries including South Africa, Kenya, Tunisia, Morocco, Sudan and the Democratic Republic of Congo (DRC) where such waves have severely impacted the health system by straining the supply of oxygen and ICU beds and inflicting a heavy toll on healthcare workers, often necessitating the re-imposition of control measures.

Surveillance of Populations at High Risk for HIV Transmission
Epidemics of infectious diseases are occurring more often, and spreading faster and further than ever, in many different regions of the world. The ...background factors of this threat are biological, environmental and lifestyle changes, among others. A potentially fatal combination of newly-discovered diseases, and the re-emergence of many long-established ones, demands urgent responses in all countries. Planning and preparation for epidemic prevention and control are essential. The purpose of this “Managing epidemics” manual is to provide expert guidance on those responses.

Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances,... by ingestion of contaminated food or drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.

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 t...he 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 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.

Situation analysis
Description of the disaster
An Ebola epidemic that started in March 2014 in Guinea has relentlessly continued to claim lives and to spread to other countries in West Africa. The current Ebola outbreak is the largest in hist...ory and the first to affect multiple countries simultaneously. There have been over 24 000 reported confirmed, probable, and suspected cases of EVD in Guinea, Liberia and Sierra Leone (table 1), with almost 10 000 reported deaths (outcomes for many cases are unknown). A total of 58 new confirmed cases were reported in Guinea, 0 in Liberia, and 58 in Sierra Leone in the 7 days to 8 March (4 days to 5 March for Liberia). Many experts believe that the official numbers substantially understate the size of the outbreak because of families' widespread reluctance to report cases. Because of the fluidity of movement of people between West Africa and several countries in the East African countries, especially Kenya and Ethiopia (who in turn have extensive interaction with other countries in the region in terms of human movement), the risk of an outbreak of Ebola in East Africa is as eminent as in any of the countries bordering the affected countries. The IFRC regional office intends to support National Societies to raise their Ebola preparedness and response capacity through training, technical support in planning and implementation of Ebola related activities, and coordination both within and outside the movement.

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.

Infectious diseases cause over one billion human infections per year, with millions of deaths each year globally. Extensive health and financial bu...rden is seen from both established and emerging infectious diseases. Infectious diseases also affect plants and animals, which may pose threats to agriculture and water supplies with additional impacts on human health. This Question and Answers, prepared by the World Health Organization (WHO) and Convention on Biological Diversity (CBD) Secretariat under their joint work programme on biodiversity and health, and launched of the occasion of the International Day for Biodiversity 2020, summarizes some of the interlinkages between biodiversity and infectious diseases.
WHO is continuously monitoring and responding to the COVID 19 outbreak. This Q&A will be updated as more is known about COVID-19, how it is affecting people worldwide, and the effectiveness of interventions against the disease.

The preparedness strengthening team deployed to Ghana focused on specific objectives in order to assist the country in becoming as operationally prepared as possible to detect, investigate and report potential EVD cases effectively and safely and to mount an effective response to prevent a larger o...utbreak. To accomplish this goal, the team conducted “scoping” activities, stakeholder meetings, site visits and a “table-top” simulation exercise to determine what systems were in place and what aspects of preparedness could be strengthened.
It is organized in 10 components of the WHO consolidated checklist for EVD preparedness: 1) planning and coordination; 2) epidemiological and laboratory surveillance; 3) rapid response teams; 4) contact tracing; 5) points of entry; 6) laboratory; 7) case management; 8) infection prevention and control; 9) social mobilization and risk communication; 10) budget.
