(August 23, 2024 4:41 PM ET) The Jackson County Health Department has issued two alerts on West Nile Virus and Pertussis.
West Nile Virus Alert
As of August 23rd, 2024, the Jackson County Health Department has confirmed that two birds in the county tested positive for West Nile Virus (WNV). Fortunately, no human cases have been confirmed in Jackson County at this time, though there have been four human cases of West Nile virus or other arboviruses reported statewide in 2024. Mosquito pools are routinely monitored by the Jackson County Health Department and the Michigan Department of Health and Human Services (MDHHS) for WNV and other arboviruses.
Arboviruses are viruses transmitted by mosquitoes and other insects. Alongside West Nile Virus, Michigan has detected other arboviruses this summer, including Jamestown Canyon Virus and Eastern Equine Encephalitis (EEE).
West Nile Virus Symptoms:
Most people infected with West Nile Virus do not experience symptoms. However, about 1 in 5 may develop mild symptoms such as:
– Fever
– Headache
– Body aches
– Fatigue
– Skin rash (occasionally)
In rare cases, severe symptoms can occur, including:
– High fever
– Severe headache
– Neck stiffness
– Disorientation or confusion
– Muscle weakness
– Tremors or seizures
– Vision loss
If you experience any of these severe symptoms, seek medical attention immediately.
Prevention Tips:
Mosquito Control
– Use screens on windows and doors; repair any holes.
– Weekly, eliminate standing water around your home where mosquitoes can breed.
– Discard old tires, cans, and containers.
– Repair failed septic systems.
– Drill holes in recycling containers left outdoors.
– Keep grass short and shrubbery trimmed.
– Clean roof gutters regularly.
– Replace water in pet bowls frequently.
– Maintain ornamental fountains and birdbaths by flushing or aerating.
Use Insect Repellent
– Choose EPA-registered insect repellents containing:
– DEET
– Picaridin
– IR3535
– Oil of Lemon Eucalyptus (OLE) or PMD
– 2-Undecanone
– These repellents are safe for use, even during pregnancy and breastfeeding. Find the right repellent using the EPA’s search tool: EPA Insect Repellent Search
Pertussis Alert
Pertussis, also known as whooping cough, has been identified in Jackson and nearby counties. This highly contagious illness is caused by bacteria and spreads through direct contact or by inhaling droplets from an infected person’s cough or sneeze. Pertussis can be especially dangerous for babies and young children who are not fully vaccinated.
Symptoms typically appear 7-10 days after exposure, but it can take up to 3 weeks in some cases. Early signs resemble a common cold—sneezing, runny nose, mild dry cough, and a low-grade fever. After 1-2 weeks, more severe coughing fits may develop, sometimes lasting over a minute and making breathing difficult. A “whooping” sound may occur as the person tries to catch their breath, and coughing can cause gagging or vomiting, particularly at night. These coughing episodes can persist for 6 weeks or more.
Fortunately, pertussis can be treated with antibiotics. If you suspect you were exposed to pertussis, you may also receive a prophylactic dose of antibiotics to avoid becoming sick.
Thankfully, pertussis vaccines have made the disease less common, with most children receiving protection through routine vaccinations. However, immunity from the vaccine fades over time. If you or your children are over 10, a booster shot may be necessary. Having pertussis once does not provide long-term immunity, so it’s important to keep vaccination records up to date.
Healthcare providers are urged to maintain vigilance in diagnosing and treating pertussis, especially in children or childcare workers who may have been exposed. Partially vaccinated children may not exhibit classic symptoms, such as the “whoop,” but can still transmit the disease. Recommended diagnostic tests include culture or PCR of a nasopharyngeal (NP) swab or aspirate.
Serology and DFA tests are not recommended. For additional information from MDHHS on recommended tests to perform, see the link below.
Please report any suspected pertussis cases to the Jackson County Health Department for investigation and classification based on national guidelines by phone at 517-768-1664.
