7While this difference between the status quo is and future potential is large, it mirrors the shift in disease burden in Lyme disease which was once believed to be < 30,000, and is now thought to number > 475,000 based on administrative claims data. 8

| ● | Treatment of Acute Babesiosis. There are up to 38,000 cases of potentially treatable acute symptomatic babesiosis (red blood cell infections caused by deer tick bites) in the United States each year.9 Approximately 650 of these cases are hospitalizations, a smaller fraction of which represents immunosuppressed individuals.10 Symptomatic babesiosis is usually treated with a minimum ten day course of atovaquone and azithromycin which is extended to six weeks in the immunosuppressed, who may also experience relapses requiring multiple hospitalizations.11 This is much longer than equivalent serious parasitic diseases such as malaria where the goal is a three-day regimen. In a recently published case series Tafenoquine in combination with standard of care cured 80% of immunosuppressed patients with relapsing babesiosis and the investigators stated in a press release that “Tafenoquine is going to make a huge difference, I think, in people who are severely immunocompromised.” 12 |

| 4 | Previously, we had estimated the maximum prevalence of chronic babesiosis to be 1.01 million by multiplying the rate of Babesia coinfection in PTLDS patients (52%, from Parveen & Bhanot, Pathogens 2019;8(3):117) by the highest estimate of the cumulative prevalence of PTLDS (1,994,189, from Delong et al. BMC Public Health 2019;19(1):352). However, since it was recently determined that only 41% of hospitalized babesiosis patients have Lyme as a coinfection (Ssentongo et al Open Forum Infect Dis 2024 Oct 8;11(10)) total prevalence might be as high as 2.46 million (divide 1.01 million by 41%). Our recent survey of 6,000 U.S. consumers suggested that 3 million U.S. adults have experience babesiosis based on 1.26% of responders reporting have received such a medical diagnosis from a healthcare provider. Based on molecular epidemiology studies we have sponsored, we have made the operational
