Florida Health Officials Confirm Dengue Case, Urge Mosquito Precautions

Florida Health Officials Confirm Dengue Case, Urge Mosquito Precautions

The Florida Department of Health in Miami-Dade County has confirmed a locally acquired case of dengue fever. Health officials are coordinating with Miami-Dade County Mosquito Control to enhance surveillance, prevention, and control efforts against mosquito-borne illnesses. Dengue, transmitted by the Aedes aegypti mosquito, can cause severe flu-like symptoms, including muscle and joint pain, fever, and rash. The agency is urging residents to take precautions against mosquito bites and continues to monitor other mosquito-borne diseases such as West Nile virus, eastern equine encephalitis, St. Louis encephalitis, malaria, and chikungunya. Residents are also encouraged to report dead birds to the Florida Fish and Wildlife Conservation Commission as part of the surveillance efforts.

Climate Change Accelerates Spread of Infectious Diseases in Southern Africa

Climate Change Accelerates Spread of Infectious Diseases in Southern Africa

Southern Africa is experiencing a significant increase in cholera outbreaks, exacerbated by climate change. Cyclone-driven floods have damaged water infrastructure, contaminated drinking water supplies, and displaced hundreds of thousands of people, particularly in Mozambique. The bacterium Vibrio cholerae, which causes cholera, thrives in aquatic environments, and warmer water, flooding, and plankton blooms have dramatically increased bacterial concentrations, creating ideal conditions for outbreaks. In early 2026, southern Africa saw a seven-fold increase in cholera cases compared to the previous year, with 13 African countries reporting simultaneous outbreaks. This situation highlights the broader impact of climate change on public health, as it creates conditions conducive to the spread of various infectious diseases.

Jamestown Canyon Virus Detected in Mosquitoes in New Hampshire Communities

Jamestown Canyon Virus Detected in Mosquitoes in New Hampshire Communities

Mosquito batches in Hampton and Derry, New Hampshire, have tested positive for the Jamestown Canyon Virus. This virus can be transmitted to humans and may cause serious neurological issues, such as meningitis. Other communities, including Exeter, Fremont, Kingston, and Salem, have also reported positive mosquito batches. Despite these findings, there have been no reported human or animal cases of the virus this year.

Jamestown Canyon Virus Detected in Mosquito Batches in New Hampshire Communities

Mosquito batches in Hampton and Derry, New Hampshire, have tested positive for the Jamestown Canyon Virus, a virus that can be transmitted to humans and cause serious neurological issues such as meningitis. Additional positive mosquito batches have been identified in Exeter, Fremont, Kingston, and Salem. Despite these findings, there have been no reported human or animal cases of the virus this year. The detection of the virus in these areas highlights the ongoing need for public health monitoring and mosquito control efforts to prevent potential outbreaks.

DR Congo Ebola Epidemic Becomes World's Second Largest Outbreak

DR Congo Ebola Epidemic Becomes World's Second Largest Outbreak

The Ebola epidemic in the Democratic Republic of the Congo (DRC) has become the world's second largest outbreak, with over 3,500 confirmed cases. The outbreak, caused by the Bundibugyo strain of the virus, has resulted in 1,556 deaths, with a case fatality rate of 44.1 percent. The rapid spread of the virus has prompted calls for increased global attention and resources to contain the epidemic.

ECDC Reports on Chikungunya and Other Communicable Disease Threats in Europe

ECDC Reports on Chikungunya and Other Communicable Disease Threats in Europe

The European Centre for Disease Prevention and Control (ECDC) has released its weekly Communicable Disease Threats Report, covering the period from July 27 to 31, 2026. The report provides updates on various public health threats, including chikungunya virus disease, Ebola, West Nile Virus infections, and others. It serves as a critical resource for epidemiologists and health professionals, offering insights into the current epidemiological situation in the EU/EEA. The report highlights ongoing surveillance and response efforts to manage these threats, emphasizing the importance of preparedness and collaboration among health authorities.

Bourbon Virus Confirmed in New York: A New Tick-Borne Threat Emerges

Bourbon Virus Confirmed in New York: A New Tick-Borne Threat Emerges

For the first time, Bourbon virus has been confirmed in New York, with a case identified in a 67-year-old Suffolk County man. The virus, carried by lone star ticks, has previously been confirmed only six times in the U.S. The disease is difficult to diagnose due to the lack of commercial tests and its symptoms overlap with other tick-borne illnesses. Testing of ticks and deer in New York has shown that the virus is more prevalent than previously thought, with evidence of active transmission in Suffolk County and other parts of the state.

Israeli Authorities Intensify Efforts as West Nile Virus Detected in Mosquitoes

Israeli Authorities Intensify Efforts as West Nile Virus Detected in Mosquitoes

In southern Israel, the West Nile virus has been detected in mosquitoes, prompting local authorities to enhance prevention, monitoring, and public awareness efforts. The Health Ministry and the Environmental Protection Ministry have confirmed the presence of the virus in the Tamar Regional Council area. This discovery has led to increased mosquito control measures across the country. Since the beginning of the year, six cases of West Nile fever have been diagnosed in Israel. The risk of further outbreaks is heightened between June and November, coinciding with peak mosquito activity. The virus, transmitted to humans through mosquito bites, is not spread from person to person. Most cases are mild, but serious complications can occur, particularly in vulnerable populations such as older adults and those with weakened immune systems.

Chikungunya IgG Test: Key Tool for Confirming Past Infections and Managing Long-term Symptoms

Chikungunya IgG Test: Key Tool for Confirming Past Infections and Managing Long-term Symptoms

The Chikungunya IgG test is a diagnostic tool used to detect the presence of immunoglobulin G antibodies in the blood, indicating past infection with the chikungunya virus. This test is particularly useful for confirming previous infections, evaluating persistent joint pain, and supporting clinical diagnoses. It is performed by collecting a blood sample, which is then analyzed for IgG antibodies. A positive result suggests past exposure to the virus and the development of an immune response, while a negative result indicates no previous exposure or testing too early before antibody development. The test is crucial for individuals who have experienced symptoms consistent with chikungunya, such as severe joint pain and fever, and for those living in or traveling to areas where the virus is prevalent.

Mercy Corps Faces Challenges in Ebola Response Amidst DRC Outbreak

Mercy Corps Faces Challenges in Ebola Response Amidst DRC Outbreak

Mercy Corps, an international aid organization, is grappling with significant challenges in responding to the Ebola outbreak in the Democratic Republic of Congo (DRC). The outbreak, which has resulted in over 1,500 deaths, is the fastest-growing in the region's history. Mercy Corps' teams are finding it increasingly difficult to reach affected communities due to community mistrust, insecurity from armed conflicts, and gaps in healthcare infrastructure. Onesphore Bangenza, the Ebola response team leader for Mercy Corps in Bunia, highlighted the alarming rate of new cases, which are comparable to the 2018-2020 outbreak. The organization is also facing shortages in basic supplies necessary for safe burials, further complicating containment efforts.

Nature Conference on Infectious Diseases to Convene Global Experts at MAHE, Manipal

Nature Conference on Infectious Diseases to Convene Global Experts at MAHE, Manipal
