Update on Skaneateles Lake Water Sampling
Onondaga County Health Commissioner Dr. Indu Gupta was notified this evening that the samples taken earlier today in Skaneateles Lake show non-detectable levels of toxin in drinking water reaching customers of the system, including the City of Syracuse, the Town of Dewitt, the Village of Skaneateles, the Town of Skaneateles, the Town of Elbridge, the Village of Elbridge, and the Village of Jordan. Although low levels of toxin continue to be found in untreated drinking water, the treated water shows no indication of toxin.
The New York State Department of Health has advised the City of Syracuse that sampling is not necessary over the weekend since the algal blooms have dissipated. The City will continue to visually monitor the lake for the presence of blooms over the weekend and routine water sampling will start again on Monday.
The Onondaga County Health Department reminds residents to NEVER drink untreated surface water, whether or not harmful algal blooms are present. Residents who draw water directly from the lake through near-shore PRIVATE INTAKES should take the following precautions:
- DO NOT USE the water for potable purposes such as drinking, making infant formula, making ice, brushing teeth, preparing food, or washing dishes, or for pets.
- If either algae blooms or scums are present in the vicinity of your water intake, do not use the water for bathing.
To be clear, these recommendations apply only to residents with private intakes; in-home treatments such as boiling, disinfecting water with chlorine or ultraviolet radiation (UV), and water filtration units do not remove the toxins associated with harmful algal blooms.

Low Levels of Algal Toxins Detected in Skaneateles Lake Water
Onondaga County Health Commissioner Dr. Indu Gupta announced today that the City of Syracuse has reported low levels of algal toxins found in their routine water samples of the untreated intakes in Skaneateles Lake. Results are well below health advisory limits for the general population. Skaneateles Lake is used by several municipalities as a public drinking water supply. Small shoreline algal blooms have been confirmed on the lake this week. Samples of both raw and treated drinking water are being tested now and the community will be informed of the results. Enhanced monitoring through daily testing will continue until all samples consistently return to non-detectable results.

Death of Horse Due to West Nile Virus Infection, Spraying Planned for Town of Lysander
Onondaga County Health Commissioner, Dr. Indu Gupta, was notified by the New York State Department of Health Wadsworth Laboratory that a horse in the Town of Lysander has died from West Nile virus (WNV) infection. Dr. Gupta explains that, “West Nile virus is spread by the bite of an infected mosquito; therefore it is extremely important that people use personal protection measures to reduce their risk of being bitten by mosquitoes.”
There have been no virus findings in mosquito surveillance traps in the area where the horse was located, however, due to the death of the horse the Onondaga County Health Department (OCHD) will be intensifying trapping in this area and is planning to conduct truck spraying. The spraying will take place on Monday, September 20 after 7:00 pm, weather permitting. The product used will be Anvil 10+10 ULV and a label can be found at https://www.ongov.net/health/documents/AnvilProductLabel.pdf A written copy of the label can be provided by calling 315.435.1649.
This proactive measure is done in an attempt to interrupt the virus cycle in the mosquito population. If weather or wind conditions are unfavorable, the spraying will be conducted on the next appropriate day. Residents in the spray areas will be also notified by phone through the 911 emergency notification system. A map of the spray area is available at https://www.ongov.net/health/env/documents/SprayMapLysander.pdf.
If you live in the spray area, from 7:00 pm to 10:00 pm on the day of the scheduled spraying, it is recommended that you:
- Stay indoors and keep your windows closed for one hour after the area has been sprayed.
- Keep your pets indoors if possible.
- Set your window air conditioners to circulate indoor air. It is safe to use your central air conditioning.
- Keep outdoor gardens covered and rinse vegetables before eating.
- Be sure children’s toys, outdoor furniture, and clothes on outdoor clotheslines are brought inside. If toys or clothes are left outdoors, wash each thoroughly with soap and water before using and launder clothes before wearing them.
- Close your car windows and car vents if you are driving during the spraying.
This season OCHD reported one finding of WNV, in a mosquito pool from a trap located near the Cicero Swamp on August 25. There have been no findings of Eastern Equine Encephalitis (EEE) virus in Onondaga County this year. As a whole, numbers of mosquitoes in the surveillance traps remain average for the season, however, the recent heavy rains and heat have resulted in the mosquito population being higher than usual for this time of year.
West Nile Virus
Most people who are infected with WNV do not develop symptoms. One in five people with mild cases may develop fever, headache, body aches, joint pains, or rash. People with severe illness usually have a high fever, sudden headache, neck stiffness, altered mental status, inflammation of the brain or membrane of the spinal cord (encephalitis or meningitis). People at greatest risk of developing severe disease are those over 60 years of age and people with certain medical conditions such as cancer, diabetes, hypertension, or who have received organ transplants.
Protect Yourself from Mosquito Bites
This finding of WNV in a horse serves as a reminder for all residents that the virus is present and to be consistent in protecting yourself and your family from mosquito bites no matter where you live.
Personal protection is recommended during outdoor activities by wearing shoes, socks, long pants, and a long-sleeved shirt when outside for a long period of time. Use insect repellents containing DEET, Picaridin, IR3535, oil of lemon eucalyptus, and other products that have been approved by the Environmental Protection Agency (EPA). Follow the manufacturer’s instructions on proper use for safety and effectiveness. Insect repellents should be applied only to intact skin or over clothing. Do NOT apply DEET or Picaridin directly onto children’s skin—apply to your own hands and then put it on the child. Repellent should never be used on babies younger than 2 months old.
Given the significant amount of rainfall in Onondaga County recently, it is extremely important to remove mosquito breeding grounds by eliminating any standing water that may have collected on your property:
- Throw away outdoor containers, ceramic pots or containers that hold water
- Remove all tires from your property
- Drill holes in the bottoms of recycling containers that are kept outdoors
- Clean clogged rain gutters and make sure they continue to work properly
- Turn over wheelbarrows and wading pools when not in use
- Change water in birdbaths at least every four days
- Clear vegetation and debris from the edges of ponds
- Clean chlorinated swimming pools, outdoor saunas, and hot tubs
- Drain water from pool covers
- Use landscaping to eliminate low spots where standing water accumulates
The Onondaga County Health Department remains in close contact with the New York State Departments of Health and Environmental Conservation.

Overdose Awareness Day—August 31st
Local communities around the world are coming together on Overdose Awareness Day to remember those who have passed away or suffered permanent injury due to drug overdose. In 2020, the CDC reported that 93,000 people died from an opioid overdose in the midst of the pandemic, with 156 of those deaths occurring locally in Onondaga County. Dr. Indu Gupta, Onondaga County Commissioner of Health explained that “efforts to stop the opioid crisis are more vital than ever, as the pandemic has exacerbated risk factors such as high unemployment rates, social isolation, and despair, as well as the disruption of available treatment and harm reduction support services that individuals with substance use may depend on.”
Observed on August 31st every year, International Overdose Awareness Day seeks to create a better understanding of overdose, reduce the stigma of drug-related deaths, and create change that reduces the harms associated with drug use. Locally, the Onondaga County Health Department has partnered for the second year in a row with Prevention Network for an Overdose Awareness Day event on Tuesday, August 31st. There will be drive-thru naloxone training, fentanyl testing strips, educational materials, and more. The event will take place in the Prevention Network parking lot at 906 Spencer Street, Syracuse from 3:00 to 7: 00 pm. This event is open to the public and free of charge.
Dr. Gupta urged that “addressing opioid use and overdose is an urgent public health priority, and making potentially lifesaving treatments more readily available is an important way to address this crisis.” Naloxone remains the most powerful tool in preventing opioid overdose deaths and is a safe medication that counteracts the effects of an opioid overdose. Dr. Gupta continued, “This is a vital component of the three-pronged approach taken by the Onondaga County Health Department to address the opioid epidemic.” The approach includes the following:
- Preventing substance use disorders by ensuring safe drug disposal, implementing appropriate prescribing practices, increasing community awareness of the opioid crisis, and reducing the stigma associated with substance use disorders.
- Treating substance use disorders by providing timely access to treatment and recovery options, along with appropriate linkages to follow-up care.
- Reversing opioid overdoses through the effective distribution and use of naloxone, and ensuring long-term supports for people pursuing recovery.”
Each of these strategies is a vital component of reversing the opioid crisis. If you are unable to attend the event on August 31st and would like to take a virtual training please visit www.ongov.net/health/opioids/NaloxoneTraining.html to see available training options community-wide.
Mosquitoes Found Positive for West Nile Virus
Onondaga County Health Commissioner, Dr. Indu Gupta, was notified by the New York State Department of Health Wadsworth Laboratory today that a mosquito pool from a trap located at Island Road in the town of Cicero has tested positive for West Nile virus (WNV). Dr. Gupta explains that “West Nile virus is spread by the bite of an infected mosquito; therefore it is extremely important that people use personal protection measures to reduce their risk of being bitten by mosquitoes.” This is the first positive finding of WNV in mosquitoes in Onondaga County since 2019.

Two Mosquito Pools Found Positive for Jamestown Canyon Virus
Onondaga County Health Commissioner Dr. Indu Gupta announced today that lab results show the presence of the Jamestown Canyon virus in two mosquito pools, one from a trap located on Midler Avenue in Syracuse, and another located in Onondaga Lake Park in Liverpool. This is the first finding of the virus in mosquitoes in Onondaga County since 2014. There have been no known human cases in Onondaga County.
This finding is a result of the Health Department’s mosquito surveillance and control program which collects and tests mosquitoes for viruses. The program also uses larvicides (insecticides) to control mosquito breeding in standing bodies of water. While this virus is rare, the Health Department will report any future findings as part of their weekly mosquito pool testing.
Dr. Gupta explained that, “Jamestown Canyon virus is spread to people by infected mosquitoes. Many people have no symptoms and do not get sick, but some have symptoms such as fever, headache, fatigue, cough and sore throat. Very rarely it can develop into encephalitis. The best way to reduce your risk of infection is by avoiding mosquito bites.”
Personal Protection Measures
The Health Department reminds residents that there are steps everyone should take to protect themselves from mosquito bites during outdoor activities:
- Wear shoes, light-colored socks, long pants, and a long-sleeved shirt. Tuck in your shirt and tuck pant legs into boots or socks.
- Consider using insect repellents containing DEET, Picaridin, IR3535, oil of lemon eucalyptus, and other products that have been approved by the Environmental Protection Agency (EPA). Use this EPA search tool to help you choose the repellent product that is right for you, and follow the manufacturer’s instructions on proper use for safety and effectiveness. Insect repellents should be applied only to intact skin or over clothing. Do NOT apply DEET or Picaridin directly onto children’s skin (apply to your own hands and then put it on the child). Repellent should not be used on babies younger than 2 months old.
- Treat clothing and gear with products containing 0.5% permethrin. Permethrin can be used to treat boots, clothing, and camping gear and remain protective through several washings. Alternatively, you can buy permethrin-treated clothing and gear.
Mosquito-Proof Your Home
It is also important to mosquito-proof your home by replacing or repairing broken screens and getting rid of standing water where mosquitoes breed. Keep your property free of standing water by cleaning clogged rain gutters; turning over wheelbarrows and wading pools when not in use; changing water in birdbaths every four days; properly maintaining swimming pools, outdoor saunas, and hot tubs; draining water from pool covers; and, using landscaping to eliminate low spots where standing water accumulates.
Signs and Symptoms
According to the CDC, there were 4 cases of Jamestown Canyon virus disease reported in New York State from 2010 to 2019. Although many people infected with Jamestown Canyon virus do not have symptoms, the virus can cause severe disease.
- For people with symptoms, the time from mosquito bite to feeling sick ranges from a few days to 2 weeks.
- Initial symptoms can include fever, fatigue, and headache. Some people also have respiratory symptoms such as cough, sore throat, or runny nose.
- Jamestown Canyon virus can cause severe disease, including infection of the brain (encephalitis) or the membranes around the brain and spinal cord (meningitis).
- Symptoms of encephalitis or meningitis include stiff neck, confusion, loss of coordination, difficulty speaking, or seizures.
- About half of patients reported with Jamestown Canyon virus disease are hospitalized.
- Deaths associated with Jamestown Canyon virus infection are rare.
Contact your healthcare provider if you have recently been bitten by a mosquito and are experiencing flu-like symptoms.

Clift Park Beach in Village of Skaneateles Closed for Swimming
The Onondaga County Health Department announced today that Clift Park Beach located in the Village of Skaneateles will be closed for swimming due to high levels of bacteria (E.coli) in the water. Swimming will not be allowed until bacteria levels return to acceptable levels. The Health Department will be monitoring the lake water daily until bacteria levels reach acceptable standards and will notify the public when the beach is reopened for swimming.
Most varieties of E. coli are harmless or cause brief diarrhea. While only some types of bacteria will cause gastrointestinal illness, the presence of E. coli bacteria is an indicator of increased general bacterial action in the water. Anyone concerned about gastrointestinal symptoms should contact their health care provider.
For more information, please call the Division of Environmental Health at 315.435.6600.
