West Nile Virus Detected in Cumberland County Mosquitoes: What You Need to Know

Table of Contents

Cumberland County, PA, is on alert after the Vector Control Office confirmed the presence of West Nile Virus (WNV) in two mosquito samples. The Pennsylvania Department of Environmental Protection (DEP) identified the infected mosquitoes on Wednesday, July 2, 2025, prompting increased surveillance and targeted mosquito control measures.

Confirmed Cases and Locations

The DEP discovered the first WNV-positive mosquito in South Middleton Township, near Carlisle Airport, on tuesday, July 1. the second was found the following day in Shiremanstown Borough, specifically at Shiremanstown Memorial Park.

Did You Know? …

West Nile Virus is not spread from person to person. It is indeed transmitted through the bite of an infected mosquito, which contracts the virus by feeding on infected birds.

Who is most at Risk?

According to Dr. John D. Goldman, an infectious disease specialist at UPMC, young children (5 and under) and older adults (65 and over) face the highest risk of severe illness from WNV. While most healthy individuals experience mild or no symptoms, these age groups are more susceptible to complications.

Pro Tip: …

The CDC recommends using EPA-registered insect repellents containing DEET, picaridin, IR3535, oil of lemon eucalyptus (OLE), para-menthane-diol (PMD), or 2-undecanone for effective mosquito bite prevention (CDC).

Preventative Measures

cumberland County officials urge residents to take the following precautions to minimize the risk of mosquito bites and WNV transmission:

  • Apply mosquito repellents containing DEET.
  • Wear long-sleeved shirts and pants, especially during peak mosquito activity.
  • Take extra precautions during dusk and dawn, when female mosquitoes are most active.
  • Ensure window and door screens are secure and in good repair.
  • Eliminate standing water around your property, as it provides breeding grounds for mosquitoes.

Declining Prevalence Expected

Dr. Goldman anticipates a continued decline in WNV cases due to increasing immunity within the population. many individuals have

Tiger Mosquito Surveillance Intensified in Ordizia Amid Public health concerns

Table of Contents

The City Council of Ordizia, Spain, has launched an intensive entomological surveillance campaign to monitor and control the population of the Tiger Mosquito (dengue-vaccine-shows-nearly-80-efficacy-in-clinical-trials-health-magazine/” title=”… Vaccine Shows Nearly 80% Efficacy in Clinical Trials | Health | Magazine”>Aedes albopictus) due to concerns over its painful bites and potential to transmit diseases. The initiative, conducted through the Neiker company and part of a broader effort within the Euskadi Autonomous Community, aims to mitigate the risks associated with this invasive species.

Why the Tiger Mosquito Matters

The Tiger Mosquito,a small black insect approximately 5 mm long characterized by a distinctive white line on its head and thorax,is a daytime biter that frequently enough hides in dark places. Its bites can be particularly painful and cause significant reactions in some individuals. More critically, the Tiger Mosquito is a known vector for several viruses, including dengue, Zika, and chikungunya, posing a public health threat [[reference to CDC or WHO on mosquito-borne diseases]].

Did You Know? The Tiger Mosquito was first detected in the United States in 1985 and has since spread to many parts of the contry [[reference to EPA on mosquito species]].

Ordizia’s Control Measures

The surveillance campaign in Ordizia includes the placement of egg traps in strategic locations to monitor mosquito populations. specifically, five traps have been placed in Barrena Park and another five in the municipal cemetery. These traps allow officials to track the presence and density of the Tiger Mosquito, as well as other species like Aedes japonicus, which were also detected in the area last year.

Preventing Mosquito Breeding: A Community effort

A key aspect of controlling the Tiger Mosquito population is preventing its reproduction. These mosquitoes lay their eggs in small accumulations of water, such as those found in plant dishes, discarded containers, and clogged gutters. Residents are urged to take the following steps:

  • Empty containers that collect water at least twice a week.
  • Renew water in pet bowls every two to three days.
  • Pour water into drains weekly to prevent stagnation.
  • Use mosquito nets on windows, deposits, and containers.

Pro Tip: Regularly inspect your property for potential breeding sites, even small puddles can support mosquito larvae.

Recommendations to Avoid Bites

In addition to preventing mosquito breeding, individuals can take personal precautions to avoid being bitten:

  • Wear long sleeves, long pants, and closed footwear, especially during peak mosquito activity times (dawn and dusk).
  • Use authorized mosquito repellents containing DEET, IR3535, or picaridin.
  • pregnant women and children should prioritize physical measures like mosquito nets.

what to Do If Bitten

If you are bitten by a mosquito, clean the affected area with soap and water. Avoid scratching the bite to prevent infection. Applying a cold compress can definitely help reduce inflammation and relieve itching. In cases of severe reactions, consult a healthcare professional.

Campaign Timeline

The Tiger mosquito control campaign in Ordizia is scheduled to continue until mid-November, reflecting the period when mosquito activity is typically highest.

Chikungunya Vaccine Could Halt Millions of Infections Globally

New Analysis Highlights Potential of Targeted Immunization Campaigns

A comprehensive new study reveals that a focused vaccination strategy using the IXCHIQ vaccine could dramatically reduce the worldwide impact of chikungunya, a rapidly spreading mosquito-borne illness. Researchers modeled the potential benefits, identifying high-risk regions for prioritized intervention.

Global Disease Burden

The review, published in Nature Medicine, quantified the global impact of chikungunya virus (CHIKV). Analyses of 180 countries showed that 104 experience CHIKV transmission, exposing an estimated 2.8 billion people. Approximately 35.3 million infections occur annually, with outbreaks recurring roughly every 6.2 years.

Gilles Ribeiro dos Santos and colleagues used multidisciplinary data—seroprevalence, surveillance systems, and mosquito distribution—to estimate the global burden and model vaccination benefits. The study specifically focused on the IXCHIQ vaccine (VLA1553, Valneva), recently licensed based on immunological indicators rather than traditional phase 3 efficacy trials.

Vaccination Impact and Projections

Modeling scenarios, assuming 70% vaccine efficacy, 40% infection protection, and 50% coverage, suggest targeted vaccination could prevent 4,400 infections, 0.35 deaths, and 17 disability-adjusted life years (DALYs) per 100,000 doses. The impact is projected to be 83% greater in epidemic regions compared to endemic areas.

The researchers emphasize that these projections are sensitive to factors like vaccine characteristics, coverage rates, and the speed of outbreak response. Effective immunization strategies require rapid detection and efficient deployment.

CHIKV transmission classifications map. Endemic: CHIKV circulates persistently. Epidemic: CHIKV circulates sporadically. No transmission: CHIKV does not circulate.

Understanding Chikungunya

Chikungunya is a viral disease transmitted by Aedes mosquitoes. Symptoms include fever, joint pain, and rash, with approximately half of acute cases experiencing chronic joint pain. While CHIKV-associated mortality is rare, the disease’s increasing prevalence and impact on vulnerable populations—infants, the elderly—underscores the need for proactive public health measures.

According to the World Health Organization, cases of chikungunya have been reported in over 110 countries and territories, with significant outbreaks in Africa, Asia, and the Americas. WHO Chikungunya Fact Sheet (June 2024)

The Path Forward

The study highlights the importance of understanding CHIKV’s global reach to develop effective immunization strategies. The licensing of vaccines like IXCHIQ and VIMKUNYA represents a significant step forward, but targeted deployment based on risk assessment is crucial.

Ribeiro dos Santos and the team conclude that their findings provide a quantified rationale for prioritizing high-risk regions and optimizing vaccine use to reduce morbidity and mortality worldwide. Continued monitoring and adaptation of vaccination strategies will be essential for long-term success.

Lower Saxony: New virus variant – Chinese disease wipes out rabbits | Regional

by Chief editor of world-today-news.com
written by Chief editor of world-today-news.com

Baltrum (Lower Saxony) – Bunny sat in the hole and slept… Poor bunny, are you sick that you can’t hop anymore? This classic has been sung in our kindergartens since the 19th century. Death has actually crept into millions of rabbit burrows. From Schleswig-Holstein to Bavaria, animal rights activists are watching the drama and are powerless.

The so-called China disease is killing our rabbits. The disease is caused by the RHD virus, which first appeared in China in 1984 and has been raging in Germany with increasing severity every year since 2016.

All rabbit species are threatened by the Chinese disease – despite very high reproduction rates

On Baltrum (Lower Saxony), hunter and animal rights activist Jann Bengen observes the development with concern: “In fact, the situation on the mainland is now dramatic, because the few surviving rabbits are being hunted by other predators such as foxes, martens and Wolf are under pressure.” In cities, many rabbits also fall victim to Domestic cats.

This is why the cute rodents are disappearing nationwide despite their extremely high reproduction rate. The Frisian Association for Nature Conservation estimates that the number of rabbits in Germany, which once numbered millions, has declined by over 90 percent since the early 2000s.

Infection mostly via fleas

The only hope is the islands. “There are three East Frisian Islands Rabbits, whose numbers are also declining significantly, but we have no predators on the ground here except for free-roaming domestic cats. That gives us hope,” says Jann Bengen. He believes that the population here could increase again.

The virus is transmitted via fleas and mosquitoes, and everyone in the den quickly becomes infected. Fatal: If the den is too full, rabbits wander off and form new colonies. After a certain incubation period, the next wave of deaths begins.

Domestic rabbits and hares are also threatened

Animal rights activists are currently concerned about a new RHD variant. Bengen: “Until now, hares have not been affected by RHD. The new variant is making them sick and causing them to die as well.”

Are our domestic rabbits also threatened? Bengen: “All rabbits are affected. Vaccinations are essential. However, domestic and stable rabbits are infected less by fleas and more by biting, blood-sucking insects, in particular Mosquitoes.“

In the Northeast, the West Nile virus is present in 1% of mosquitoes – News – Ansa.it

by Chief editor of world-today-news.com
written by Chief editor of world-today-news.com

The presence of West Nile virus in mosquitoes sampled in Veneto and Friuli Venezia Giulia is about 1%. This is what appears from the latest data expressed by the laboratory of health psychology and vector-borne pathogens of the Istituto Zooprophylattico Sperimentale delle Venezie (Izsve).

Although the distribution of the virus in mosquitoes is moderate – the institute specifies in a note – the risk to human health should not be underestimated. According to the latest bulletin in Veneto, there are actually eight cases of neuroinvasive West Nile and four of West Nile fever, but the numbers could increase in the coming weeks as the heat summer continues.

The Izsve entomological study includes the use of 92 traps to catch mosquitoes, between Veneto (64) and Friuli Venezia Giulia (28). An investigation began in May and will continue until October. The traps take place one night every 15 days for each site, in an alternate way, so that traps are active every week for each province.

As of August 5, in Veneto out of 1,659 pools of mosquitoes examined, 22 were found positive for WNV (1.33%) and 2 for Usutu Virus, while in Friuli Venezia Giulia there were 2 positive pools out of 245 (0.82%); they all consisted of Culex pipiens, the common mosquito.

The situation is different for Dengue fever, a disease transmitted by the tiger mosquito, with the largest number of cases in Italy (283), but all are imported. In Veneto the incidence has quadrupled compared to 2023, with 55 cases, and the regional journal also reports cases of Zika (2), Chikungunya (1) and Oropouche fever (1), also from abroad.

“Fortunately this year – mentions Zooprophylactic Director, Antonia Ricci – the spread of West Nile is very limited, even if the attention of the health authorities is always very high after the recent cases in Padua and Pordenone. Unlike the cases of Dengue, Chikungunya and Zika reported in people returning from travel abroad, especially in South America and tropical countries, the West Nile virus is endemic in our area and therefore the probability of catching the disease is higher Therefore it is important to adopt the correct habits to avoid mosquito bites in this way it is possible to reduce the risk of infection, especially for categories of vulnerable people such as the elderly and immunocompromised “.
