The current Ebola virus disease (EVD) outbreak ravaging three nations in West Africa has affected more than 14,000 persons and killed over 5,000. It is the longest and most widely spread Ebola epidemic ever seen. ⋯ What lessons can we learn from Nigeria, Senegal and Ghana in the current epidemic? How can the world improve the health systems in low- and middle-income countries to effectively manage future outbreaks? Recently, the Royal College of Physicians launched a new partnership with the West African College of Physicians to curtail the effects of HIV/AIDS, malaria and tuberculosis in the region. We believe that strengthened health systems, skilled human resources for health and national ownership of problems are key to effective management of outbreaks such as EVD.

Tick-borne infections are seen throughout the United States, with varying geographical locations. Many of these infections are also increasingly seen in Europe. Certain ticks (eg Ixodes) can transmit more than one infection. ⋯ In certain situations, empiric therapy may be required for tick-borne infections as severe illness with multiorgan failure can occur, particularly in older and immunocompromised hosts. This review describes the more commonly seen tick-borne infections: Lyme, babesiosis, anaplasmosis and Rocky Mountain Spotted Fever. More recently identified tick-borne infections, such as southern tick-associated rash illness and Borrelia miyamotoi, are also covered.

Brucella and Coxiella are similar; both are obligate intracellular, zoonotic pathogens with a broad geographic distribution. Infection in animals is usually asymptomatic, but causes fetal loss and therefore has significant economic impact. ⋯ Therefore, infection is most commonly diagnosed by serology, but this may be negative in early infection and serology results may be challenging to interpret. Both Brucella and Coxiella are typically susceptible to a wide range of antimicrobials, but long courses may be needed.
