RESUMO
Dengue is an arbovirus transmitted by the Aedes spp. mosquito. Approximately 390 million infections occur annually per World Health Organization estimates, with significant increases in infections throughout the last decade. The disease is endemic in warmer climates throughout the world, though cases may also be imported to non-endemic regions by returning travelers. Patients experience a wide variety of symptoms ranging from asymptomatic infection to severe disease requiring critical care. Emergency clinicians should consider the diagnosis of dengue in patients from endemic areas presenting with a flu-like illness, rash, and evidence of bleeding.

INTRODUCTION: Candida auris is an emerging pathogen and human health threat. However, diagnosis and treatment of fungal infection due to C. auris are challenging. OBJECTIVE: This narrative review provides a focused overview of C. auris for the emergency clinician. DISCUSSION: C. auris was first identified in 2009 and is currently present on all continents except Antarctica. C. auris possesses multiple genetic factors resulting in antimicrobial resistance, increased virulence and survival within the host, and environmental adaptation. It is readily transmitted from person to person and from the environment to a person, resulting in colonization. Infection may develop days to months following colonization, most commonly in those with immunocompromised state, significant comorbidities or other underlying conditions, healthcare exposure, and recent antimicrobial therapy. Candidemia, device infection (e.g., central venous catheter), soft tissue or wound infection, burn infection, osteomyelitis, myocarditis, meningitis, and urinary tract infection have been associated with C. auris. Samples should be obtained from the suspected site of infection for microbiological culture. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) with reference databases to differentiate C. auris from other species is optimal for diagnosis, though other molecular testing methods are available. Treatment is challenging due to antifungal resistance, with over 90% resistant to fluconazole. Echinocandins are most commonly used as the first line therapy. Prevention of colonization and infection are vital and include screening in high-risk populations and strict adherence to infection prevention practices with contact precautions and hand hygiene, as well as appropriate decontamination of patient areas. CONCLUSION: An understanding of C. auris can assist emergency clinicians in the care of infected or colonized patients.

INTRODUCTION: Malaria is a potentially fatal parasitic disease transmitted by the Anopheles mosquito. A resurgence in locally acquired infections has been reported in the U.S. OBJECTIVE: This narrative review provides a focused overview of malaria for the emergency clinician, including the epidemiology, presentation, diagnosis, and management of the disease. DISCUSSION: Malaria is caused by Plasmodium and is transmitted by the Anopheles mosquito. Disease severity can range from mild to severe. Malaria should be considered in any returning traveler from an endemic region, as well as those with unexplained cyclical, paroxysms of symptoms or unexplained fever. Patients most commonly present with fever and rigors but may also experience cough, myalgias, abdominal pain, fatigue, vomiting, and diarrhea. Hepatomegaly, splenomegaly, pallor, and jaundice are findings associated with malaria. Although less common, severe malaria is precipitated by microvascular obstruction with complications of anemia, acidosis, hypoglycemia, multiorgan failure, and cerebral malaria. Peripheral blood smears remain the gold standard for diagnosis, but rapid diagnostic tests are available. Treatment includes specialist consultation and antimalarial drugs tailored depending on chloroquine resistance, geographic region of travel, and patient comorbidities. Supportive care may be required, and patients with severe malaria will require resuscitation. Most patients will require admission for treatment and further monitoring. CONCLUSION: Emergency medicine clinicians should be aware of the presentation, diagnosis, evaluation, and management of malaria to ensure optimal outcomes.

INTRODUCTION: Emergency departments (EDs) play an integral role in a community's response to disaster. Terrorist attacks targeting EDs have the potential to disrupt the emergency response apparatus. Understanding prior attacks against EDs can yield important lessons to mitigate the impact of future violence. METHODS: In this review, the authors used the Global Terrorism Database to conduct a search on terrorist attacks targeting EDs between 1970 and 2018. Using the search terms "doctor," "nurses," "hospital," "healthcare," "clinic," "vaccinators," and "vaccinations," a total of 2322 healthcare-specific incidents were isolated. The database was further narrowed down to terrorist attacks targeting EDs, using the search terms "emergency," "emergency department," and "emergency ward." RESULTS: A total of six attacks involving five countries were isolated. These attacks occurred between 1991 and 2016, with the majority involving the use of explosive devices, killing a total of 57 victims and leaving 26 wounded. CONCLUSION: Attacks against EDs, while rare, have the potential to lead to loss of life through both the direct attack and subsequent disruptions to healthcare.

INTRODUCTION: Primary disasters may result in mass casualty events with serious injuries, including crush injury and crush syndrome. OBJECTIVE: This narrative review provides a focused overview of crush injury and crush syndrome for emergency clinicians. DISCUSSION: Millions of people worldwide annually face natural or human-made disasters, which may lead to mass casualty events and severe medical issues including crush injury and syndrome. Crush injury is due to direct physical trauma and compression of the human body, most commonly involving the lower extremities. It may result in asphyxia, severe orthopedic injury, compartment syndrome, hypotension, and organ injury (including acute kidney injury). Crush syndrome is the systemic manifestation of severe, traumatic muscle injury. Emergency clinicians are at the forefront of the evaluation and treatment of these patients. Care at the incident scene is essential and focuses on treating life-threatening injuries, extrication, triage, fluid resuscitation, and transport. Care at the healthcare facility includes initial stabilization and trauma evaluation as well as treatment of any complication (e.g., compartment syndrome, hyperkalemia, rhabdomyolysis, acute kidney injury). CONCLUSIONS: Crush injury and crush syndrome are common in natural and human-made disasters. Emergency clinicians must understand the pathophysiology, evaluation, and management of these conditions to optimize patient care.

INTRODUCTION: Acute bacterial meningitis in adults is a rare but serious condition that carries a high rate of morbidity. OBJECTIVE: This review highlights pearls and pitfalls of acute bacterial meningitis in adults, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION: Meningitis encompasses a broad spectrum of disease involving inflammation of the meninges and subarachnoid space. It classically presents with fever, nuchal rigidity, and altered mental status, but this triad is not present in all cases. Up to 95% of patients will have at least two of the following four cardinal symptoms: fever, nuchal rigidity, altered mental status, and headache. The most common bacterial etiologies are S. pneumoniae and N. meningitidis. Cerebrospinal fluid testing obtained by lumbar puncture remains the gold standard in diagnosis. Head computed tomography prior to lumbar puncture may not be necessary in most patients. Empiric treatment consists of vancomycin, ceftriaxone, and dexamethasone. Elevated intracranial pressure should be managed using established neurocritical care strategies. CONCLUSION: A better understanding of the pearls and pitfalls of acute bacterial meningitis can assist emergency clinicians in pursuing its timely diagnosis and management.

INTRODUCTION: Mpox, formerly known as monkeypox, is a public health emergency most commonly presenting with a painful rash and several systemic findings. However, there are several conditions that may mimic its presentation. OBJECTIVE: This narrative review provides a focused overview of mpox mimics for emergency clinicians. DISCUSSION: Mpox is a global health emergency. The disease is primarily spread through contact, followed by the development of a centrifugally-spread rash that evolves from macules to papules to vesicles to pustules. This is often associated with lymphadenopathy and fever. As the rash is one of the most common presenting signs of the infection, patients mpox may present to the emergency department (ED) for further evaluation. There are a variety of mimics of mpox, including smallpox, varicella, primary and secondary syphilis, acute retroviral syndrome, and genital herpes simplex virus. CONCLUSION: Knowledge of mpox and its mimics is vital for emergency clinicians to differentiate these conditions and ensure appropriate diagnosis and management.

INTRODUCTION: Ebolavirus, the causative agent of Ebola virus disease (EVD) has been responsible for sporadic outbreaks mainly in sub-Saharan Africa since 1976. EVD is associated with high risk of transmission, especially to healthcare workers during patient care. OBJECTIVE: The purpose of this review is to provide a concise review of EVD presentation, diagnosis, and management for emergency clinicians. DISCUSSION: EVD is spread through direct contact, including blood, bodily fluids or contact with a contaminated object. Patients may present with non-specific symptoms such as fevers, myalgias, vomiting, or diarrhea that overlap with other viral illnesses, but rash, bruising, and bleeding may also occur. Laboratory analysis may reveal transaminitis, coagulopathy, and disseminated intravascular coagulation. The average clinical course is approximately 8-10 days with an average case fatality rate of 50%. The mainstay of treatment is supportive care, with two U.S. Food and Drug Administration-approved monoclonal antibody treatments (Ebanga and Inmazeb). Survivors of the disease may have a complicated recovery, marked by long-term symptoms. CONCLUSION: EVD is a potentially deadly condition that can present with a wide range of signs and symptoms. Emergency clinicians must be aware of the presentation, evaluation, and management to optimize the care of these patients.

BACKGROUND: Urine cultures are nonspecific and often lead to misdiagnosis of urinary tract infection and unnecessary antibiotics. Diagnostic stewardship is a set of procedures that modifies test ordering, processing, and reporting in order to optimize diagnosis and downstream treatment. In this study, we aimed to develop expert guidance on best practices for urine culture diagnostic stewardship. METHODS: A RAND-modified Delphi approach with a multidisciplinary expert panel was used to ascertain diagnostic stewardship best practices. Clinical questions to guide recommendations were grouped into three thematic areas (ordering, processing, reporting) in practice settings of emergency department, inpatient, ambulatory, and long-term care. Fifteen experts ranked recommendations on a 9-point Likert scale. Recommendations on which the panel did not reach agreement were discussed during a virtual meeting, then a second round of ranking by email was completed. After secondary review of results and panel discussion, a series of guidance statements was developed. RESULTS: One hundred and sixty-five questions were reviewed. The panel reaching agreement on 104, leading to 18 overarching guidance statements. The following strategies were recommended to optimize ordering urine cultures: requiring documentation of symptoms, sending alerts to discourage ordering in the absence of symptoms, and cancelling repeat cultures. For urine culture processing, conditional urine cultures and urine white blood cell count as criteria were supported. For urine culture reporting, appropriate practices included nudges to discourage treatment under specific conditions and selective reporting of antibiotics to guide therapy decisions. CONCLUSIONS: These 18 guidance statements can optimize use of urine cultures for better patient outcomes.

INTRODUCTION: Monkeypox is an emerging viral disease that has been declared a global health emergency. While this disease has been present for over 50 years, the recent surge in cases and expanding knowledge of this has prompted a need for a focused review for practicing clinicians. OBJECTIVE: This narrative review provides a focused overview of the epidemiology, presentation, evaluation, and management of monkeypox for emergency clinicians. DISCUSSION: Monkeypox is an orthopoxvirus endemic to central and western Africa. An outbreak in May and June 2022 across Asia, Europe, North America, and South America was declared a global health emergency in July 2022. The disease can be transmitted via contact with an infected animal or human, as well as contact with a contaminated material. The disease presents with a prodromal flu-like illness and lymphadenopathy. A rash spreading in a centrifugal manner involving the oral mucosa, face, palms, and soles is typical. Lesions progress along various stages. Complications such as bacterial skin infection, pneumonitis, ocular conditions, and encephalitis are uncommon. Confirmation typically includes polymerase chain reaction testing. The majority of patients improve with symptomatic therapy, and as of July 2022, there are no United States Food and Drug Administration-approved treatments specifically for monkeypox. However, antiviral treatment should be considered for several patient populations at risk for severe outcomes. CONCLUSION: An understanding of the presentation, evaluation, and management of monkeypox is essential for emergency clinicians to ensure appropriate diagnosis and treatment of this emerging disease.

INTRODUCTION: Coronavirus disease of 2019 (COVID-19) has resulted in millions of cases worldwide. As the pandemic has progressed, the understanding of this disease has evolved. OBJECTIVE: This narrative review provides emergency clinicians with a focused update of the resuscitation and airway management of COVID-19. DISCUSSION: Patients with COVID-19 and septic shock should be resuscitated with buffered/balanced crystalloids. If hypotension is present despite intravenous fluids, vasopressors including norepinephrine should be initiated. Stress dose steroids are recommended for patients with severe or refractory septic shock. Airway management is the mainstay of initial resuscitation in patients with COVID-19. Patients with COVID-19 and ARDS should be managed similarly to those ARDS patients without COVID-19. Clinicians should not delay intubation if indicated. In patients who are more clinically stable, physicians can consider a step-wise approach as patients' oxygenation needs escalate. High-flow nasal cannula (HFNC) and non-invasive positive pressure ventilation (NIPPV) are recommended over elective intubation. Prone positioning, even in awake patients, has been shown to lower intubation rates and improve oxygenation. Strategies consistent with ARDSnet can be implemented in this patient population, with a goal tidal volume of 4-8 mL/kg of predicted body weight and targeted plateau pressures <30 cm H2O. Limited data support the use of neuromuscular blocking agents (NBMA), recruitment maneuvers, inhaled pulmonary vasodilators, and extracorporeal membrane oxygenation (ECMO). CONCLUSION: This review presents a concise update of the resuscitation strategies and airway management techniques in patients with COVID-19 for emergency medicine clinicians.

INTRODUCTION: Coronavirus disease of 2019 (COVID-19) has resulted in millions of cases worldwide. As the pandemic has progressed, the understanding of this disease has evolved. OBJECTIVE: This is the second part in a series on COVID-19 updates providing a focused overview of the medical management of COVID-19 for emergency and critical care clinicians. DISCUSSION: COVID-19, caused by Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), has resulted in significant morbidity and mortality worldwide. A variety of medical therapies have been introduced for use, including steroids, antivirals, interleukin-6 antagonists, monoclonal antibodies, and kinase inhibitors. These agents have each demonstrated utility in certain patient subsets. Prophylactic anticoagulation in admitted patients demonstrates improved outcomes. Further randomized data concerning aspirin in outpatients with COVID-19 are needed. Any beneficial impact of other therapies, such as colchicine, convalescent plasma, famotidine, ivermectin, and vitamins and minerals is not present in reliable medical literature. In addition, chloroquine and hydroxychloroquine are not recommended. CONCLUSION: This review provides a focused update of the medical management of COVID-19 for emergency and critical care clinicians to help improve care for these patients.

INTRODUCTION: Coronavirus disease of 2019 (COVID-19) has resulted in millions of cases worldwide. As the pandemic has progressed, the understanding of this disease has evolved. Its impact on the health and welfare of the human population is significant; its impact on the delivery of healthcare is also considerable. OBJECTIVE: This article is another paper in a series addressing COVID-19-related updates to emergency clinicians on the management of COVID-19 patients with cardiac arrest. DISCUSSION: COVID-19 has resulted in significant morbidity and mortality worldwide. From a global perspective, as of February 23, 2022, 435 million infections have been noted with 5.9 million deaths (1.4%). Current data suggest an increase in the occurrence of cardiac arrest, both in the outpatient and inpatient settings, with corresponding reductions in most survival metrics. The frequency of out-of-hospital lay provider initial care has decreased while non-shockable initial cardiac arrest rhythms have increased. While many interventions, including chest compressions, are aerosol-generating procedures, the risk of contagion to healthcare personnel is low, assuming appropriate personal protective equipment is used; vaccination with boosting provides further protection against contagion for the healthcare personnel involved in cardiac arrest resuscitation. The burden of the COVID-19 pandemic on the delivery of cardiac arrest care is considerable and, despite multiple efforts, has adversely impacted the chain of survival. CONCLUSION: This review provides a focused update of cardiac arrest in the setting of COVID-19 for emergency clinicians.

INTRODUCTION: Coronavirus disease of 2019 (COVID-19) has resulted in millions of cases worldwide. As the pandemic has progressed, the understanding of this disease has evolved. OBJECTIVE: This first in a two-part series on COVID-19 updates provides a focused overview of the presentation and evaluation of COVID-19 for emergency clinicians. DISCUSSION: COVID-19, caused by Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), has resulted in significant morbidity and mortality worldwide. Several variants exist, including a variant of concern known as Delta (B.1.617.2 lineage) and the Omicron variant (B.1.1.529 lineage). The Delta variant is associated with higher infectivity and poor patient outcomes, and the Omicron variant has resulted in a significant increase in infections. While over 80% of patients experience mild symptoms, a significant proportion can be critically ill, including those who are older and those with comorbidities. Upper respiratory symptoms, fever, and changes in taste/smell remain the most common presenting symptoms. Extrapulmonary complications are numerous and may be severe, including the cardiovascular, neurologic, gastrointestinal, and dermatologic systems. Emergency department evaluation includes focused testing for COVID-19 and assessment of end-organ injury. Imaging may include chest radiography, computed tomography, or ultrasound. Several risk scores may assist in prognostication, including the 4C (Coronavirus Clinical Characterisation Consortium) score, quick COVID Severity Index (qCSI), NEWS2, and the PRIEST score, but these should only supplement and not replace clinical judgment. CONCLUSION: This review provides a focused update of the presentation and evaluation of COVID-19 for emergency clinicians.

The COVID-19 pandemic provided the specialty of emergency medicine the opportunity to showcase what many knew all along: emergency physicians (EP) are well suited to deal with the unknown and can quickly adapt even with incomplete or limited information and resources. Emergency physicians in Missouri served in integral positions locally, nationally and internationally. Missouri EPs published numerous manuscripts on topics from basic science to clinical care. Device innovation also occurred with the development of protective devices for health care workers. As we approach the three-year mark of the COVID-19 pandemic, the burden of clinical care still weighs heavily on EPs. Each wave of the pandemic has brought challenges and spurred EPs to innovate in new ways. As Michigan EP Brian Zink, MD once said "Anyone, Anything, Anytime". These words correctly sum up emergency medicine. When others hesitated to care for COVID-19 patients, EPs stepped up despite uncertainty and risks to their own health. Emergency medicine has led the way and continues to innovate and push the envelope of emergency care.

BACKGROUND: Since its emergence in late 2019, SARS-CoV-2 continues to pose a risk to healthcare personnel (HCP) and patients in healthcare settings. Although all clinical interactions likely carry some risk of transmission, human actions like coughing and care activities like aerosol-generating procedures likely have a higher risk of transmission. The rapid emergence and global spread of SARS-CoV-2 continues to create significant challenges in healthcare facilities, particularly with shortages of personal protective equipment (PPE) used by HCP. Evidence-based recommendations for what PPE to use in conventional, contingency, and crisis standards of care continue to be needed. Where evidence is lacking, the development of specific research questions can help direct funders and investigators. OBJECTIVE: Develop evidence-based rapid guidelines intended to support HCP in their decisions about infection prevention when caring for patients with suspected or known COVID-19. METHODS: IDSA formed a multidisciplinary guideline panel including frontline clinicians, infectious disease specialists, experts in infection control, and guideline methodologists with representation from the disciplines of public health, medical microbiology, pediatrics, critical care medicine and gastroenterology. The process followed a rapid recommendation checklist. The panel prioritized questions and outcomes. Then a systematic review of the peer-reviewed and grey literature was conducted. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the certainty of evidence and make recommendations. RESULTS: The IDSA guideline panel agreed on eight recommendations, including two updated recommendations and one new recommendation added since the first version of the guideline. Narrative summaries of other interventions undergoing evaluations are also included. CONCLUSIONS: Using a combination of direct and indirect evidence, the panel was able to provide recommendations for eight specific questions on the use of PPE for HCP providing care for patients with suspected or known COVID-19. Where evidence was lacking, attempts were made to provide potential avenues for investigation. There remain significant gaps in the understanding of the transmission dynamics of SARS-CoV-2 and PPE recommendations may need to be modified in response to new evidence. These recommendations should serve as a minimum for PPE use in healthcare facilities and do not preclude decisions based on local risk assessments or requirements of local health jurisdictions or other regulatory bodies.
RESUMO
INTRODUCTION: High flow nasal cannula (HFNC) is a noninvasive ventilation (NIV) system that has demonstrated promise in the emergency department (ED) setting. OBJECTIVE: This narrative review evaluates the utility of HFNC in adult patients with acute hypoxemic respiratory failure in the ED setting. DISCUSSION: HFNC provides warm (37 °C), humidified (100% relative humidity) oxygen at high flows with a reliable fraction of inspired oxygen (FiO2). HFNC can improve oxygenation, reduce airway resistance, provide humidified flow that can flush anatomical dead space, and provide a low amount of positive end expiratory pressure. Recent literature has demonstrated efficacy in acute hypoxemic respiratory failure, including pneumonia, acute respiratory distress syndrome (ARDS), coronavirus disease 2019 (COVID-19), interstitial lung disease, immunocompromised states, the peri-intubation state, and palliative care, with reduced need for intubation, length of stay, and mortality in some of these conditions. Individual patient factors play an important role in infection control risks with respect to the use of HFNC in patients with COVID-19. Appropriate personal protective equipment, adherence to hand hygiene, surgical mask placement over the HFNC device, and environmental controls promoting adequate room ventilation are the foundation for protecting healthcare personnel. Frequent reassessment of the patient placed on HFNC is necessary; those with severe end organ dysfunction, thoracoabdominal asynchrony, significantly increased respiratory rate, poor oxygenation despite HFNC, and tachycardia are at increased risk of HFNC failure and need for further intervention. CONCLUSIONS: HFNC demonstrates promise in several conditions requiring respiratory support. Further randomized trials are needed in the ED setting.

INTRODUCTION: Rapid worldwide spread of Coronavirus Disease 2019 (COVID-19) has resulted in a global pandemic. OBJECTIVE: This review article provides emergency physicians with an overview of the most current understanding of COVID-19 and recommendations on the evaluation and management of patients with suspected COVID-19. DISCUSSION: Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for causing COVID-19, is primarily transmitted from person-to-person through close contact (approximately 6 ft) by respiratory droplets. Symptoms of COVID-19 are similar to other viral upper respiratory illnesses. Three major trajectories include mild disease with upper respiratory symptoms, non-severe pneumonia, and severe pneumonia complicated by acute respiratory distress syndrome (ARDS). Emergency physicians should focus on identifying patients at risk, isolating suspected patients, and informing hospital infection prevention and public health authorities. Patients with suspected COVID-19 should be asked to wear a facemask. Respiratory etiquette, hand washing, and personal protective equipment are recommended for all healthcare personnel caring for suspected cases. Disposition depends on patient symptoms, hemodynamic status, and patient ability to self-quarantine. CONCLUSION: This narrative review provides clinicians with an updated approach to the evaluation and management of patients presenting to the emergency department with suspected COVID-19.

BACKGROUND: Emergency departments (EDs) play an essential role in the timely initiation of HIV post-exposure prophylaxis (PEP) for sexual assault victims. METHODS: Retrospective analysis of sexual assault victims evaluated and offered HIV PEP in an urban academic ED between January 1, 2005 and January 1, 2018. Data on demographics, comorbidities, nature of sexual assault, initial ED care, subsequent healthcare utilization within 28 days of initial ED visit, and evidence of seroconversion within 6 months of the initial ED visit were obtained. Predictors of subsequent ED visit and follow-up in the infectious diseases clinic were evaluated using logistic regression analysis. RESULTS: Four hundred twenty-three ED visits met criteria for inclusion in this study. Median age at ED presentation was 25 years (IQR 21-34 years), with the majority of victims being female (95.5%), Black (63.4%), unemployed (66.3%) and uninsured (53.9%); psychiatric comorbidities (38.8%) and substance abuse (23.6%) were common. About 87% of the patients accepted HIV PEP (368 of 423 ED visits). Age (OR 0.97, 95% CI 0.94-0.99, p = 0.025) and sexual assault involving >1 assailant (OR 0.48, 95% CI 0.26-0.88, p = 0.018) were associated with lower likelihood of HIV PEP acceptance. Ten patients (2.7%) followed up with the infectious disease clinic within 28 days of starting HIV PEP; 70 patients (19%) returned to the ED for care during the same time period. Psychiatric comorbidity (OR 2.48, 95% CI 1.43-4.30, p = 0.001) and anal penetration (OR 2.02, 95% CI 1.10-3.70, p = 0.024) were associated with greater likelihood of repeat ED visit; female gender (OR 0.30, 95% CI 0.11-0.85, p = 0.023) was associated with lower likelihood of repeat visit. Completion of HIV PEP was documented for 14 (3.3%) individuals. CONCLUSIONS: While ED patient acceptance of HIV PEP after sexual assault was high, infectious disease clinic follow-up and documented completion of PEP remained low. Innovative care models bridging EDs to outpatient clinics and community support services are needed to optimize transitions of care for sexual assault victims, including those receiving HIV PEP.

BACKGROUND: The national rate of syphilis has increased among persons who inject drugs (PWID). Missouri is no exception, with increases in early syphilis (ES), congenital syphilis, and PWID, especially in nonurban counties. METHODS: Disease intervention specialist records for ES cases in Missouri (2012-2018) were examined. Drug use was classified as injection drug use (IDU) (opioid or methamphetamine) or non-IDU (opioid, methamphetamine, or cocaine). Rates were compared based on residence, sex of sex partner, and drug use. RESULTS: Rates of ES in Missouri increased 365%, particularly in small metropolitan and rural areas (1170%). Nonurban areas reported a higher percentage of persons with ES who used injection drugs (12%-15%) compared with urban regions (2%-5%). From 2012 to 2018, women comprised an increasing number of ES cases (8.3%-21%); 93% of women were of childbearing age. Increasingly more women in rural areas with ES also reported IDU during this time (8.4%-21.1%). CONCLUSIONS: As syphilis increases in small metropolitan and rural regions, access to high-quality and outreach-based sexual health services is imperative. Healthcare policy to equip health departments with harm reduction services and drug treatment resources offers an opportunity to impact both syphilis increases as well as health outcomes associated with IDU.
