Early detection, assessment and response to acute public health events:
WHO Guideline. Since 2010, countries in the meningitis belt have started to introduce a new serogroup A meningococcal conjugate vaccine conferring individual protection and herd immunity. Following the successful roll-out of this vaccine, epidemics due to Neisseria meningitidis serogroup A (NmA) are... disappearing, but other serogroups (e.g. NmW, NmX and NmC) still cause epidemics, albeit at a lower frequency and of a smaller size. Due to these changes, WHO organized the review of the evidence to provide recommendations for epidemic control, related to operational thresholds for investigation and response to outbreaks, the use of rapid diagnostic tests, antibiotic regimens in epidemics, and prophylaxis for household contacts of cases

This study aimed to determine the drug resistance profile of Mycobacterium tuberculosis in Mozambique and concludes that M. tuberculosis resistance to antituberculosis drugs is high in Mozambique, especially in previously treated patients. The frequency of M. tuberculosis strains that were resistant... to isoniazid, rifampin, and streptomycin in combination was found to be high, particularly in samples from previously treated patients.

The era of effective antibiotics is coming to a close. In just a few generations, many “miracle medicines”have been beaten into ineffectiveness by the bacteria they were intended to eradicate. Bacteria quickly adapt to the presence of antibacterial agents in order ...to survive. The misuse of antibiotics,which is an international problem, only exacerbates the steady evolution of resistance. In August 2010, the journal Lancet Infectious Diseases posed the question "Is this the end of antibiotics?" documentingthe rapid spread of multidrug-resistant bacteriaand predicting that 10 years remain in the useful life of many agents.

There is a broad consensus nowadays that the Earth is warming up as a result of greenhouse gas emissions caused by anthropogenic activities. It is also clear that current trends in the fields of energy, development and population growth will lead to continuous and ever more dramatic climate change. ...This is bound to affect the fundamental prerequisites for maintaining good health: clean air and water, sufficient food and adequate housing. The planet will warm up gradually, but the consequences of the extreme weather conditions such as frequent
storms, floods, droughts and heat-waves will have sudden onset and acute repercussions. It is widely accepted that climate change will have an impact on the spread of infectious diseases in Europe, which is likely to bring about new public health risks in the majority of cases. Transmission of infectious diseases depends on a number of factors, including climate and environmental elements. Foodborne and waterborne diseases, for instance, are associated with high temperatures. Disease-transmitting vectors (e.g. mosquitoes, sandflies and ticks) are highly sensitive to climate conditions, including temperature and humidity; their geographical distribution will widen as climate conditions change, potentially allowing them to spread into regions where they are not currently able to live.
The primary purpose of this manual on climate change and infectious diseases is to raise the awareness and the level of knowledge of health workers at national, regional and local levels in the former Yugoslav Republic of Macedonia on the health risks associated with climate change and infectious diseases. This manual was devel-
oped as part of the WHO Regional Office for Europe project, Protecting health from climate change: a seven–country initiative, implemented with financial support from the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety.

Dengue is a mosquito-borne viral disease that occurs mainly in the tropics and subtropics but has a high potential to spread to new areas. Dengue infections are climate sensitive, so it is important to better understand how changing climate factors affect the potential for geographic spread and futu...re dengue epidemics. Vectorial capacity (VC) describes a vector's propensity to transmit dengue taking into account human, virus, and vector interactions. VC is highly temperature dependent, but most dengue models only take mean temperature values into account. Recent evidence shows that diurnal temperature range (DTR) plays an important role in influencing the behavior of the primary dengue vector Aedes aegypti. In this study, we used relative VC to estimate dengue epidemic potential (DEP) based on the temperature and DTR dependence of the parameters of A. aegypti. We found a strong temperature dependence of DEP; it peaked at a mean temperature of 29.3°C when DTR was 0°C and at 20°C when DTR was 20°C. Increasing average temperatures up to 29°C led to an increased DEP, but temperatures above 29°C reduced DEP. In tropical areas where the mean temperatures are close to 29°C, a small DTR increased DEP while a large DTR reduced it. In cold to temperate or extremely hot climates where the mean temperatures are far from 29°C, increasing DTR was associated with increasing DEP. Incorporating these findings using historical and predicted temperature and DTR over a two hundred year period (1901-2099), we found an increasing trend of global DEP in temperate regions. Small increases in DEP were observed over the last 100 years and large increases are expected by the end of this century in temperate Northern Hemisphere regions using climate change projections. These findings illustrate the importance of including DTR when mapping DEP based on VC.
