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.

En este módulo, aprenderá sobre investigaciones de contactos de tuberculosis (TB).
A las personas que han estado expuestas a un caso* de enfermedad de tuberculosis infecciosa se las conoce como “contactos de tuberculosis”. Una investigación de contactos de tuberculosis consiste en una estrat...egia
de control de la tuberculosis que se utiliza para identificar, buscar y evaluar contactos de tuberculosis y proporcionar el tratamiento apropiado para la infección de tuberculosis latente (ITBL) o para la enfermedad de tuberculosis, si fuera necesario. Las investigaciones eficaces de contactos interrumpen la propagación de la tuberculosis en las comunidades y ayudan a prevenir los brotes de tuberculosis.
Para obtener información más detallada, consulte el material de los Centros
para el Control y la Prevención de Enfermedades (CDC): Pautas para la investigación de los contactos de personas con tuberculosis infecciosa (Guidelines for the Investigation of Contacts of Persons with Infectious
Tuberculosis), disponible en el sitio web de los CDC (www.cdc.gov/tb).

Humanitarian crises can affect women, men, girls and boys in radically different ways. To address the different impacts of conflict and disasters on each group and promote the potential for positive transformation of gender norms, Oxfam calls for humanitarian agencies to analyse, plan, and respond t...o crises in ways that address practical gender needs and promote women’s rights. Oxfam is committed to promoting gender equality and preventing gender-based violence, through the implementation of its Minimum Standards for Gender in Emergencies. In addition, the promotion of gender equality must be central to the broader efforts to protect civilians and manage and prevent conflict and armed violence.

Cervical intraepithelial neoplasia (CIN) is a premalignant lesion that may exist at any one of three stages: CIN1, CIN2, or CIN3. If left untreated, CIN2 or CIN3 (collectively referred to as CIN2+) can progress to cervical cancer. Instead of screening and diagnosis by the standard sequence of cytolo...gy, colposcopy, biopsy, and histological confirmation of CIN, an alternative method is to use a ‘screen-and-treat’ approach in which the treatment decision is based on a screening test and treatment is provided soon or, ideally, immediately after a positive screening test. This guideline provides recommendations for strategies for a screen-and-treat programme
