EEE Virus Map Near Me: State-by-State List of Cases & Deaths

EEE Virus Map

CDC EEE Virus Map

The EEE Virus (Eastern equine encephalitis) is making headlines as cases increase in the United States. This illness is transmitted by mosquitoes and a number of cases have recently been reported. The disease is still rare in humans, but the mortality rate can be as high as 33 percent when an infection evolves into encephalitis. Massachusetts and Connecticut are among the states recording human cases this year. Read on to see a map and a state-by-state list.

EEE symptoms can start out as fever, chills, and joint and muscle pain, the Texas Department of State Health Services notes. Some people only have the mild flu-like symptoms. However, about 20 percent of those infected develop a clinical illness, and about half of those go on to develop the encephalitic disease, StatNews reported. When the illness gets more serious, the symptoms can be a sudden and severe headache, a high fever, vomiting, diarrhea, disorientation, convulsions and seizures, and even coma. Although still considered rare, the disease can have a 33 percent mortality rate in those who develop the encephalitis symptoms

Here’s a look at the states that have recently reported cases of EEE in 2019. The virus is most commonly found in the northeast part of the country and along the Gulf Coast and the Great Lakes. For 2019, The following is a map of EEE cases in 2019 per state. The CDC periodically updates this map, and as of publication the most recent update was September 24. An embedded version of the map is below, but the full map can be seen here.

The map below will start out by showing the West Nile Virus, since this is the default. Click on EEE at the top of the map (WNV is auto-checked) to see EEE human cases instead. 

Here’s a screenshot below of what the map above shows as of September 24, and what you should see when you check EEE instead of WNV. The shading may be green instead of blue for you when you view the embedded map above. You can also use the + sign to zoom into specific states.

Here are where the bulk of the human cases in 2019 are. Blue shading indicates cases. The states with the most cases so far include Connecticut, Massachusetts, Michigan, and Rhode Island.

CDC

From 2009 to 2018, only 21 states recorded EEE cases for a total of 72, the CDC reports. Many states just had one solitary case. The CDC estimates about seven cases a year, sometimes ranging from 3 to 15. Between 2009 and 2018, the worst year was 2012 with 15 cases in humans. The chart below is provided by the CDC.

From recent reports, it feels like 2019 might be a higher-count year, but the statistics aren’t in yet. Here’s a look at which states are typically affected by human cases from 2009 to 2018, as shared by the CDC.

Hawaii Has Had No Human Cases in 2019

From 2009 to 2018, Hawaii had no reported cases of EEE in humans and has had no human cases in 2019. Hawaii.gov notes: “Most arboviral diseases are not an immediate threat to Hawaii due to the lack of insects and arthropods that transmit the diseases. However, Hawaii does have species of Aedes mosquitoes that are capable of transmitting diseases such as dengue, chikungunya, and Zika virus. Aedes albopictus is widely spread throughout the state, and Aedes aegypti has been identified at sites on Hawaii Island. Hawaii’s tropical climate creates a year-round mosquito season. Therefore, after returning from their travels, it is important that infected individuals protect themselves from further mosquito bites during the first two weeks of illness to prevent local transmission of the disease.”

Rhode Island Has Had Three Human Cases of EEE & One Death

A girl in Rhode Island, 6-year-old Star Jackman, became very ill and nearly died, her parents said.

According to RI.gov, Rhode Island has had three human cases of EEE this year. The last two contracted it in late August. One was the girl from Coventry who is 6 and the other was in their 50s and from Charlestown.

The first person who was diagnosed died on September 9. All three contracted EEE before critical areas were sprayed. RI.gov noted:

The four critical risk areas that were previously sprayed were (1) an area in northern Rhode Island (parts of Burrillville, North Smithfield, and Woonsocket); (2) parts of Westerly, Hopkinton, and Charlestown; (3) all of West Warwick and parts of Coventry, Cranston, Scituate, Warwick, East Greenwich, and West Greenwich; and (4) all of Central Falls, Pawtucket, and North Providence and parts of Providence, East Providence, Smithfield, Lincoln, and Cumberland.

To date this year, EEE has been detected by RIDOH’s State Health Laboratories in six mosquito pools: two from Central Falls, three from Westerly, and one from Block Island. Additionally, one horse from Westerly has tested positive for EEE. RIDOH and DEM had previously announced that two deer had tested positive for EEE (one from Coventry and one from Richmond). A third deer from Exeter has been diagnosed this week. Deer, like horses, cannot transmit EEE to humans.
