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.

The intent of these guidelines is to develop a holistic, coordinated, proactive and technology driven strategy for management of biological disasters through a culture of prevention, mitigation and preparedness to generate a prompt and effective response in the event of an emergency. Th...e document contains comprehensive guidelines for preparedness activities, biosafety and biosecurity measures, capacity development, specialised health care and laboratory facilities, strengthening of the existing legislative/
regulatory framework, mental health support, response, rehabilitation and recovery, etc. It specifically lays down the approach for implementation of the guidelines by the central ministries/departments, states, districts and other stakeholders, in a time bound manner.

CEPI is seeking to raise $3.5 billion to implement CEPI’s next 5-year plan. To mitigate the immediate threat of COVID-19 variants, it is activating key elements of this plan now—and seeking to mobilise a portion of this $3.5 billion in 2021. We have already launched R&D programmes to initiate de...velopment of next-generation vaccines against COVID-19 variants and we are planning studies to answer critical scientific questions related to the durability of immunity, effectiveness of mixed-vaccine regimens, and vaccine effectiveness in vulnerable populations such as pregnant women. We are also bringing forward our plans to develop vaccines that could protect against multiple COVID-19 variants and other coronavirus specie

This report provides a review and analysis of the research landscape for three diseases – Chagas disease, human African trypanosomiasis and leishmaniasis – that disproportionately afflict poor and remote populations with limited access to health services. It represents the work of the disease re...ference group on Chagas Disease, Human African Trypanosomiasis and Leishmaniasis (DRG3) which was established to identify key research priorities through review of research evidence and input from stakeholders' consultations.

The Greater Horn of Africa is experiencing one of the worst food insecurity situations in decades. It is estimated
that more than 37 million people are in Integrated Food Security Phase Classification (IPC)1 phase 3 or above and approximately 7 million children under the age of five are acutely mal...nourished in the region. While finding food and safe water is the absolute priority, the health response is essential to avert preventable disease and death.
