Alpha-gal Syndrome (AGS) is an allergy to red or mammalian meat, and people with AGS can be triggered by some or many of the hundreds of mammalian meat products and byproducts (MMPBs). The American Academy of Allergy Asthma & Immunology (2019) defines Alpha-gal as a "potentially life-threatening allergy to carbohydrate molecule called galactose-alpha-1.3-galactose that is found in most mammals or red meat." AGS is common in Virginia and is transmitted by the Lone Star tick.  In October 2019, Lynchburg, VA and Richmond, Virginia made the top 10 locations represented by  members in the two primary Facebook AGS support groups with a combined 11,000+ members.  Gastrointestinal symptoms, hives, and anaphylaxis are common symptoms.

Lyme disease is the most common vector-borne disease in the United States, and is now 1.5 times more common than the estimated number of cases of breast cancer. It has been reported in all 50 states in the United States and Virginia is considered a high incidence state.  According to Tick Check, there could an estimated 200,000 true cases of Lyme disease in Virginia since 2000.   The CDC estimates close to half a million new cases of Lyme each year in the United States. Potentially, 40% of Lyme patients end up with long-term health problems or Post Treatment Lyme Disease, and only 30% actually have a bulls-eye rash. When left untreated, Lyme disease can affect the nervous and cardiovascular systems and have serious long-term health problems. Early signs and symptoms include fever, joint pain, body aches and pains, and other flu-like symptoms. Check out Tick Check's interactive map to see state and county level data since 2000. 

Cases of Rocky Mountain Spotted Fever (RMSF) have been reported throughout the United States, with 5 states accounting for over 50% of cases.  Virginia is one of these 5 states along with Arizona, Missouri, North Carolina, and Tennessee.  In Virginia, the American Dog Tick transmit the disease, which is now reported under the category of Spotted Fever Rickettsiosis (SFR).  About 5-10% of RMSF cases are fatal, with children under 10 representing the highest number of reported deaths. Early signs and symptoms include fever and headaches, and a rash may develop within a few days after the fever begins. Nausea, vomiting, stomach pain, muscle pain, and lack of appetite may also occur. The CDC describes RMSF as "one of the deadliest tick-borne diseases in the Americas." 

Anaplasmosis has been steadily increasing since it first became reportable in 2000.  The blacklegged tick which also transmits Lyme disease, transmits the disease, which has a low fatality rate of less than 1%.  The upper midwestern and northeastern regions of the United States have the highest numbers, and Virginia experience higher numbers than many states. Early signs and symptoms are fever, chills, severe headache, muscle aches, nausea, vomiting, diarrhea, and loss of appetite.  Learn more about Anaplasmosis from the CDC. 

Babesiosis has been spreading and increasing across the United States, and was reported in 40 states in 2019.  Although yet to be considered endemic in Virginia, in 2019, the Food and Drug Administration included Virginia as part of 15 states recommended to start screening blood donations for babesiosis. Some people will not have symptoms where others will experience flu-like symptoms including fever, chills, headache, body aches, j oint pain, nausea, fatigue, or loss of appetite.

Ehrlichiosis is most frequently reported in the southeastern and south-Central regions of the United States, which includes Virginia.  The state also has some of the highest rates of ehrlichiosis in dogs in the United States.  Early signs and symptoms include fever, chills, headaches, gastrointestinal symptoms, confusion or an altered mental status, and in children, sometimes a rash. CDC warns that antibiotic treatment should not be delayed in patients with suggestive clinical presentation. Learn more about Ehrlichiosis from the CDC.
