WHO Prequalifies TAK-003: New Dengue Vaccine Marks Major Breakthrough

The World Health Organization (WHO) prequalified the innovative TAK-003 dengue vaccine, designed for children aged 6-16 in high-prevalence regions. With a two-dose regimen, TAK-003 joins the WHO list alongside CYD-TDV, expanding global vaccine accessibility. Dengue, a significant public health threat, affects millions annually, highlighting the importance of advancements in vaccine development.

China Raises Concerns about Increasing Spread of Dengue Fever

Health authorities in China are concerned about the increasing spread of dengue fever, a potentially fatal viral illness transmitted by mosquitoes. With a surge of cases in Latin America and an early cluster in Guangdong province, experts warn of the challenges in disease control. Dengue, primarily transmitted by Aedes mosquitoes, peaks in China from May to November. As warmer weather approaches, preventative measures such as eliminating stagnant water are crucial to reducing the risk of dengue transmission.

Brazil Unveils Wolbachia Biofactory to Combat Dengue

The Ministry of Health, in collaboration with Fiocruz, unveiled the Wolbachia Biofactory in Belo Horizonte to combat dengue and other arboviruses. The facility will produce Aedes aegypti mosquitoes using the Wolbachia Method, playing a crucial role in preparing for future epidemics. Managed by Fiocruz and WMP, the Biofactory aims to release two million mosquitoes weekly to create a population incapable of transmitting diseases. This innovative strategy involves releasing Wolbachia-carrying mosquitoes to prevent the transmission of dengue, Zika, and chikungunya viruses.

Climate Change Amplifying Risk of Malaria Resurgence, Say Specialists

Climate change is amplifying the risk of a resurgence of malaria, with changing weather patterns creating a more favorable environment for mosquitoes to thrive. The surge in malaria cases in Mozambique’s Manica province highlights the ongoing threat posed by this disease, exacerbated by the impact of extreme weather events and food insecurity. As climate change drives environmental changes, the risk of mosquito-borne infections is expected to escalate, emphasizing the need for a comprehensive approach to disease control and prevention.

Alarming Increase in Dengue Cases Across the Americas

The latest Situation Report by the Pan American Health Organization reveals alarming statistics on the Dengue Epidemiological Situation in the Americas. With a total of 4,820,955 suspected cases reported between epidemiological weeks 1 and 13 of 2024, this represents a significant increase compared to previous years. Brazil is the primary country affected, with several others in the region also reporting cases. The data underscores the urgent need for coordinated efforts to address this epidemic.

Warning Issued for Travellers to Samoa Amid Dengue Fever Outbreak

Travellers planning to visit Samoa are being advised to ensure they have comprehensive medical and travel insurance, including provisions for medical evacuation by air, due to the ongoing dengue fever outbreak in the region. Dengue fever, a viral infection transmitted by mosquitoes, can lead to symptoms such as high fever, nausea, headaches, body aches, and rashes, with severe cases potentially resulting in death. Samoan authorities have intensified fumigation efforts to combat the spread of the disease, with most reported cases among children aged 10 years and older individuals above 60 years.

Growing Threat: Dengue Fever Spreads Amidst a Warming Planet

Learn about the growing threat of Dengue fever as it spreads amidst a warming planet. With millions falling ill annually and fatalities on the rise, the expansion of Aedes mosquitoes poses a grave risk to global health.
