The US CDC recently published its Weekly US Influenza Surveillance Report: Key Updates for Week 38 of 2025, which indicates very few influenza cases have been reported this season.

As of late September, the percentage of respiratory specimens testing positive for the influenza virus in clinical laboratories was 0.4%. However, the 2025-2026 flu season generally accelerates in late Fall, peaking during the winter months.

This influenza test data indicates that people are seeing healthcare providers for respiratory illnesses referred to as influenza-like illnesses (fever plus cough or sore throat), not laboratory-confirmed influenza.

The CDC writes that this data may capture respiratory illness visits due to infection with any pathogen that can present with similar symptoms, including influenza, SARS-CoV-2, and RSV. 

According to the World Health Organization (WHO), seasonal influenza vaccination can mitigate the impacts of annual outbreaks by preventing and mitigating the severity of infections.

As of mid-2025, 130 countries reported that seasonal flu shots were available in the public and/or private sector.

In the United States, as of September 30, 2-25, almost every pharmacy is currently offering influenza vaccinations.

Since rabies is a viral disease that is almost always fatal following the onset of clinical signs, immediate action is the best solution. 2025 marks the 19th World Rabies Day with the theme "Act Now: You, Me, Communities."

For the first time in its 19-year history, the theme does not include the word "rabies," highlighting the well-established nature of this movement, wrote the World Health Organization (WHO) on September 28, 2025.

"Whether you are an individual, part of an organization, or a decision-maker, the time to act is now."

The WHO Global Health Observatory has been updated to include newly available rabies data, supporting data-driven policy and programming. This platform offers a clearer picture of global progress and remaining gaps in data and surveillance.

Globally, most rabies cases are attributed to dog bites, according to the WHO.

However, in the United States, most rabies infections in people are a byproduct of infected bat bites.

The U.S. CDC states that rabies post-exposure prophylaxis includes wound care, human rabies immune globulin, and a four-dose vaccine series.

As a preventive measure, Bavarian Nordic's RabAvert® rabies vaccine is often recommended by travel clinics and pharmacies in the U.S.

Since the beginning of 2025, over 317,000 Chikungunya virus disease cases and 135 related fatalities have been reported in 16 countries/territories in the Americas, Africa, Asia, and Europe.

To help reduce the impact of these mosquito-transmitted Chikungunya outbreaks, various countries have recently approved vaccines. 

Regarding the long-term benefits, one vaccine manufacturer has presented very positive study results.

France-based Valneva SE today reported positive antibody persistence data four years after vaccination with a single dose of its chikungunya vaccine IXCHIQ®. The results confirm a strong and long-lasting antibody persistence across all age groups investigated.

Among the 254 healthy adults still followed in the clinical trial, 95% maintained neutralizing antibody titers well above the seroresponse threshold four years after the single-dose vaccination. The persistence of antibodies in older adults (aged 65+) was comparable to that in younger adults (18-64 years of age) in terms of geometric mean titers and seroresponse rates.

According to the trial protocol, antibody persistence is planned to be collected up to ten years after vaccination.

This study (VLA1553-303) has received funding support from the Coalition for Epidemic Preparedness Innovations and the European Union's Horizon Europe program. It has also collected long-term safety data up to two years, including Adverse Events of Special Interest from the preceding trial and any new-onset Serious Adverse Events.

No safety concerns were reported or identified.

Juan Carlos Jaramillo, M.D., Chief Medical Officer of Valneva, commented in a press release on September 30, 2025, "We are very encouraged by these four-year data, which further reinforce IXCHIQ® 's unique profile and its ability to generate a robust, durable antibody response in both younger and older adults with just a single dose."

"Whether you are a traveler, live in an endemic area, or face an outbreak situation, the prospect of long-term protection from a mosquito-borne disease with a single vaccination is highly valuable, especially in Low- and Middle-Income Countries where vaccine access is often limited."

Chikungunya is a mosquito-borne viral disease spread by the bites of infected Aedes mosquitoes which causes fever, severe joint and muscle pain, headache, nausea, fatigue and rash.

Since the re-emergence of the virus, the European Centre for Disease Prevention and Control has reported that Chikungunya has now been identified in over 110 countries. Between 2013 and 2023, more than 3.7 million cases were reported in the Americas.

Global health leaders recently discussed the final steps needed to eradicate polio during an event titled "United to Finish the Job: High-Level Side Event on Polio Eradication," which was co-hosted by the Global Polio Eradication Initiative (GPEI).

Leadership from the GPEI emphasized the need for sustained funding to complete the eradication effort, highlighting the Kingdom of Saudi Arabia's pledge of $500 million to the GPEI. This funding, along with that from other critical donors, is enabling the partnership to reach hundreds of millions of children each year with lifesaving polio vaccines and ultimately end the transmission of the virus.

Dr Tedros Adhanom Ghebreyesus, WHO Director-General, commented in a press release on September 22, 2025, "Polio eradication is a shared responsibility."

"We can finish the job only through sustained collaboration and commitment from donors such as the Kingdom of Saudi Arabia, which has been an essential supporter through its critical political, social, technical, and financial contributions."

The focus was on the urgent need to end wild polio transmission in Afghanistan and Pakistan, while also addressing outbreaks of variant poliovirus in fragile settings across Africa and Asia.

These countries and others were highlighted in the U.S. CDC's Global Polio Travel Health Notice, Level 2 - Practice Enhanced Precautions. The CDC identified 39 countries where poliovirus remains a health risk.

The CDC list includes the United Kingdom, which has previously reported detections of poliovirus in wastewater samples in London.

The CDC recommends that before any international travel, you ensure you are up to date on your polio vaccines. Adults who have previously completed the entire routine polio vaccine series may receive a single lifetime booster dose of polio vaccine.

While the US and UK governments have previously issued health advisories for ongoing Chikungunya and Measles outbreaks in the Republic of Madagascar in 2025, a Level 3, Reconsider Travel advisory was issued today.

As of September 27, 2025, the US Department of State announced that protests occur throughout the country, and they can turn violent without warning. US citizens should stay in place and avoid areas with protests or demonstrations, as protests may develop quickly, especially after dark. 

Furthermore, the State Department recommends enrolling in the Smart Traveler Enrollment Program to receive important updates and digital alerts from the US Embassy.

Enrolling helps the local embassy contact you or your designated emergency contact in the event of an emergency. For local assistance, the Embassy in Madagascar is located at Lot 207 A Andranoro, Antehiroka, 105 Antananarivo.

Moreover, have a plan to leave in an emergency that does not depend on the US government's help.

'We highly recommend purchasing travel insurance before visiting Madagascar, located off the east coast of Africa, and west of France's Mayotte and Reunion,' writes the US Embassy.

The U.S. Centers for Disease Control and Prevention (CDC) today issued a Level 2 Travel Health Advisory regarding the ongoing outbreak of Chikungunya Fever in Cuba.

Local media reported on September 26, 2025, that Andrés Lamas Acevedo, provincial director of Hygiene, Epidemiology, and Microbiology, stated the most affected territories are Matanzas, Cárdenas, Colón, Jovellanos, Jagüey Grande, and Pedro Betancourt.

Previously, in late August, the U.S. Embassy in Havana reported an increase in the number of arbovirus cases, including Chikungunya.

Chikungunya is caused by a virus that is transmitted to humans through the bites of infected mosquitoes. The CDC recommends vaccination for travelers before visiting an area with a Chikungunya outbreak.

For example, visitors from Cuba have been diagnosed in Florida with Chikungunya this year.

Additionally, the CDC advises that if you are pregnant, you should reconsider travel to the affected areas, particularly if you are close to delivering your baby. Mothers infected around the time of delivery can pass the virus to their baby before or during delivery.

Newborns infected in this way or by a mosquito bite are at risk for severe illness, including poor long-term outcomes.

In the United States, approved Chikungunya vaccines are commercailly available at travel clinics and pharmacies.

Israel's Ministry of Health today reported that another unvaccinated toddler has died from measles. This is the fifth death since the outbreak began this year, three of which occurred in the past week. 

On September 25, 2025, the Ministry's press release confirmed that 21 measles cases were hospitalized, most of them children who had not been vaccinated. Of these, six children are in intensive care. 

Additionally, the Ministry recommends an additional dose for infants in outbreak zones or before traveling to areas affected by the outbreak. 

Areas currently defined as outbreak zones: Jerusalem, Beit Shemesh, Bnei Brak, Harish, Modi’in Illit, Nof HaGalil, Kiryat Gat, and Ashdod. 

In these zones, you can visit family health centers (Tipat Halav), HMOs, and special measles vaccination stations. No appointment is needed.

In addition to measles, Israel is confronting the spread of poliovirus in 2025.

The U.S. CDC's Level 2, Practice Enhanced Precautions, Global Polio Travel Health Advisory issued on August 4, 2025, included Israel.

The CDC warns international travelers to Israel are at increased risk of exposure to poliovirus and has published updated recommendations for polio vaccinations for children and adults, which should be administered before traveling abroad.

The CDC also recommends various routine and travel vaccines before visiting Israel in 2025. These vaccines are offered in the U.S. at travel clinics and pharmacies.

The New Mexico Department of Health (NMDOH) recently declared the state's measles outbreak, which started in February 2025, to be over, as the last case was reported in Santa Fe County in mid-August.

According to the U.S. CDC, measles outbreaks are considered 'over' when 42 days pass without new cases, a timeframe that represents twice the virus's maximum incubation period.

One hundred cases of measles were identified during this outbreak, which was New Mexico's largest in decades. The outbreak began in Lea County, likely from exposures to an outbreak in neighboring Texas.

"We are thankful to the thousands of New Mexicans who received their measles, mumps, and rubella (MMR) vaccine," said Dr. Chad Smelser, NMDOH acting state epidemiologist, in a press release on September 26, 2025.

"Fully vaccinated people and those who got caught up with their vaccines during this outbreak prevented it from spreading further."

New Mexicans received over 56,000 MMR vaccines since February. The MMR vaccine remains widely available in New Mexico clinics and pharmacies for anyone who wishes to receive it.

With numerous travelers returning from African countries infected with malaria, access to treatment has become limited in the United Kingdom.

Neon Healthcare recently advised the UK's NaTHNaC that 250mg mefloquine (Lariam) antimalarial tablets are currently out of stock in the UK and will not be available until January 2026.

As of September 18, 2025, clinics and pharmacies with remaining supplies of mefloquine should prioritise travellers with imminent travel for whom mefloquine is the first choice of antimalarial. This includes pregnant travellers visiting high-risk malaria regions such as Sub-Saharan Africa.

The UK Malaria Expert Advisory Group's Malaria prevention guidelines for travellers from the UK provides detailed advice and guidance for health professionals advising travellers, and is the first port of call for queries.

As of September 26, 2025, this antimalarial shortage has not impacted travel clinics and pharmacies in the United States.

In August 2025, the New York State Health Department reported a small number of travel-associated Chikungunya Fever cases diagnosed in international travelers to countries such as France, with no identified local mosquito-borne transmission. 

New York advised healthcare providers on procedures for testing and reporting suspected cases of Chikungunya.

In related news, a Long Island resident recently tested positive for Chikungunya, marking what could be the first locally acquired case ever reported in New York state.

NY residents are encouraged to take preventive measures, such as avoiding mosquito bites, and to consult their healthcare provider before traveling to areas with a high risk of mosquito-borne diseases, which include dengue, malaria, and Zika.

On September 25, 2025, local media reported that Aedes aegypti mosquitoes, the primary ones responsible for Chikungunya virus transmission, are not naturally found in New York.

Currently, approved Chikungunya vaccination services are offered at travel clinics and pharmacies in New York.

Public Health France reported (Semaine 39-2025) today that a total of 570 locally acquired cases of Chikungunya Fever have been reported since the beginning of 2025.

The Paca region, a favorite tourist destination, is the most affected by the indigenous circulation of the Chikungunya virus.

As of September 25, 2025, mosquito-transmitted cases have been reported from Provence-Alpes-Côte d'Azur, Corsica, Occitanie, Auvergne-Rhône-Alpes, Île-de-France, Grand Est, Bourgogne-Franche-Comté, and Nouvelle-Aquitaine.

Additionally, the Ministry confirmed 993 imported cases of Chikungunya, many of whom had visited the French Departments of Mayotte and Réunion.

In total, the ongoing Chikungunya outbreak in France may set new records for the country.

As an option to prevent this disease, approved vaccines are offered in France, throughout Europe, and at travel clinics and pharmacies in the United States.

While most rabies cases in the United States are from a bite by an infected bat, a broad investigation was begun in Coffee County, Alabama, after a horse was confirmed positive for Rabies. This viral disease is almost always fatal if untreated.

The owner, family members, and a neighbor who was exposed have begun Rabies post-exposure treatment.

The horse's owners reported noticing scratch marks on her nose, and she began rubbing and showing irritation in that area. The ill horse stopped eating, symptoms worsened over the 72 hours before her death, and she became violent and started attacking and biting herself.

The owners assumed the scratches came from a fox or raccoon that she had approached. Other unvaccinated horses on the property are being observed for a period of time.  

Dr. Dee W. Jones, Alabama State Public Health Veterinarian, said in a press release on September 24, 2025, "Rabies is not as common in horses as in wildlife and domestic animals, but it is not rare. Rabies vaccines are available for horses and other livestock if recommended by a veterinarian. I encourage all horse owners to make Rabies a part of their annual vaccination, even though it is not legally required like in dogs and cats."

Vaccinating animals reduces the risk of rabies infection should exposure occur; thus, vaccinations protect animals, as well as their owners and caretakers.

Rabies prevention is multifaceted. It involves people taking precautions with wildlife, ensuring their pets are up to date on rabies vaccinations, and consistently reporting any animal bites or other exposures to their medical provider and the state health department.

The New Mexico Department of Health (NMDOH) today reported a case of plague from Bernalillo County, the second case of the year.

The 77-year-old man was hospitalized in Albuquerque and has since been discharged.

NMDOH stated in a media release on September 24, 2025, that there have been no deaths from plague in 2025.

Since 2000, an average of two human plague cases have been reported per year in New Mexico.

According to the U.S. CDC, an average of seven human plague cases are reported each year in the United States.

Plague is a bacterial disease primarily affecting rodents and is typically transmitted to humans through the bites of infected fleas, but can also be transmitted by direct contact with infected animals, including rodents, wildlife, and pets.

"The bacterium that causes plague can be found in wild rodents and their fleas throughout New Mexico," commented Dr. Erin Phipps, state public health veterinarian for the NMDOH.

"Keeping pets on the flea control product recommended by your veterinarian helps protect them and your family."

Symptoms of plague in humans include sudden onset of fever, chills, headache, and weakness. In most cases, there is a painful swelling of the lymph node in the groin, armpit, or neck.

Symptoms of plague in cats and dogs include fever, lethargy, and loss of appetite. There may be a swelling in the lymph node under the jaw.

See your doctor about any unexplained illness you may have involving sudden and severe fever.

With prompt diagnosis and appropriate antibiotic treatment, the fatality rate in people and pets can be significantly reduced. Physicians who suspect plague should promptly report to the NMDOH.

Plague vaccines have been used since the late 19th century; however, their availability remains limited in 2025.

On September 23, 2025, a Facebook post reported a total of 134 confirmed yellow fever cases (resulting in 58 deaths) in the Republic of Colombia for 2025.

The majority of cases have been reported in the Tolima Department, with 114 cases and 43 deaths.

This department is located west of Bogota, Colombia's capital city.

Other yellow fever cases have been reported in Huila, Cauca, Nariño, Putumayo, Caldas, Meta, Vaupés, and Guaviare y Caquetá.

Published in early September, the U.S. CDC's Level 2 Travel Health Notice stated some of these cases have been reported in new areas that border areas where vaccination has historically been recommended (see map). Travelers to these newly affected areas are now recommended to get vaccinated.

A booster dose may be given to sure travelers or those who received their last dose of yellow fever vaccine at least 10 years previously and will be in a higher-risk setting, such as areas in Colombia where cases have been reported.

In the United States, yellow fever vaccines are commercially offered at travel clinics and pharmacies.

Madison County Public Health (MCPH) recently announced its first recorded human case of eastern equine encephalitis (EEE) in Madison County, New York.

On September 22, 2025, MCPH stated in a press release that it had been notified of a confirmed case in a Madison County resident by the Wadsworth Center and is currently investigating. The individual is currently hospitalized for EEE infection.

This disease is often fatal (30%), and many patients who survive EEE experience neurologic impairment.

"Temperatures are getting cooler, and although we are seeing a significant decrease in mosquitoes, they remain not only a nuisance, but a potential health threat. Residents should continue to take steps to prevent mosquito bites to reduce the risk of mosquito-borne disease infection," MCPH Director Eric Faisst stated.

In July 2025, the New York State Department of Health notified MCPH of a mosquito pool that tested positive for EEE. From 1971 through 2024, 12 individuals in New York were diagnosed with EEEV; seven of them died.

About one year ago, a Ulster County resident died following an EEE infection.

This is concerning news since Madison County is located adjacent to Syracuse, New York, which has a population of over 600,000.

EEE is a rare but severe viral disease spread by infected mosquitoes that can affect people and horses. People of all ages are susceptible to infection. While most people bitten by an infected mosquito will not develop symptoms, severe cases may begin with the sudden onset of headache, high fever, chills, and vomiting.

There is no commercially available human vaccine or treatment for EEE. The best protection is to prevent mosquito bites, says MCPH.
