Introduction

Sexually transmitted diseases (STDs) have become an increasingly prominent public health concern in recent years. In the United States alone, more than 110 million people currently have an STD, with 20 million new infections occurring each year. In addition to the physical symptoms and long-term health consequences associated with many STDs, individuals who are infected may also face social stigma and psychological effects such as anxiety, depression, and decreased self-esteem. Common STDs include Chlamydia, Gonorrhea, Syphilis, Trichomoniasis and Human Papillomavirus (HPV). When left untreated or undetected these infections can cause severe health complications including infertility, pelvic inflammatory disease (PID), ectopic pregnancy, and certain types of cancer such as cervical cancer in women. Additionally, HIV/AIDS is now considered a chronic manageable illness that requires lifelong antiretroviral therapy rather than a death sentence for those infected with it.

US STD Rates

STD rates in the United States is a persistent problem that is often overlooked, yet the numbers paint a sobering picture of the prevalence of these diseases. According to 2020 data from the Centers for Disease Control and Prevention (CDC), there were 1.6 million cases of chlamydia reported in the United States, down 1.2% since 2016, making it the most commonly reported STD nationwide. Gonorrhea followed at around 677,769 cases reported, up 45% since 2016 and syphilis saw 133,945 cases reported, up 52% since 2016. These figures indicate that Americans are facing an ever-growing threat from sexually transmitted infections, with rates having increased significantly over recent years. In fact, some areas have seen increases of almost 30%, particularly among young people aged 15 to 24. Meanwhile, HIV diagnoses remain relatively stable across all demographics each year, with approximately 37,000 new diagnoses occurring annually in that age bracket nationwide. It’s clear that sexual health needs to be taken more seriously if we are to address this growing problem responsibly and reduce transmission rates accordingly.

Highest STD Rates by State

The ten states with the highest STD rates are Mississippi, Louisiana, South Carolina, Alaska, North Carolina, Alabama, Oklahoma, Tennessee, Georgia, and New Mexico. Mississippi is the state with the highest STD rate in the US, with a rate of 1,300 cases per 100,000 people. Louisiana is the second highest, with a rate of 1,100 cases per 100,000 people. South Carolina ranks third, with a rate of 999.8 per 100,000, while Alaska ranks fourth, at a rate of 990.8 per 100,000. From North Carolina, which ranks fifth, onwards with this list all the rates are below 900, with North Carolina having a rate of 898.3 per 100,000. Alabama at 857.2 ranks sixth, Oklahoma at 842.9 ranks seventh, Tennessee at 836.6 ranks eighth, Georgia at 826.9 ranks ninth, and lastly New Mexico at 818.4 per 100,000 ranks tenth.

9. Georgia – 826.9 per 100k
10. New Mexico – 818.4 per 100k

State with Highest STD Rate

Mississippi has the highest STD rate in the United States, with 1,300 cases per 100,000 people. This is much higher than the national average of approximately 600 cases per 100,000 people. The Mississippi State Department of Health reports that the majority of STD cases occur among young adults aged 15-24 and that nearly half of all new infections are among those aged 15-19. Additionally, recent studies have revealed that racial disparities exist in Mississippi regarding STD rates, with African Americans having a much higher rate than their white counterparts. This is especially concerning given that African Americans make up a large portion of Mississippi’s population. To combat this issue, Mississippi has implemented various education and prevention initiatives to raise awareness about STDs and to encourage individuals to practice safe sex.

Lowest STD Rates by State

The ten states with the lowest STD rates are Vermont, New Hampshire, Maine, Wyoming, West Virginia, Utah, Idaho, New Jersey, Massachusetts, and Connecticut. Vermont is the state with the lowest STD rate in the U.S., with a rate of 201.8 per 100,000 people. New Hampshire comes second, with a rate of 253.3. Maine ranks third with a rate of 299.3 per 100,000, and Wyoming ranks fourth, with a rate of 408.4 per 100,000. In fifth position comes West Virginia, with a rate of 409.4. Utah at 427.7 ranks sixth, Idaho at 437.5 ranks seventh, New Jersey at 478.2 ranks eighth, Massachusetts at 478.9 ranks ninth, and lastly Connecticut at 493.7 ranks tenth.

State with Lowest STD Rate

Vermont is the state with the lowest STD rate in the United States, at 201.8 cases per 100,000 people. This is remarkably low compared to the national average of 439.5 new cases diagnosed per 100,000 people nationwide. The fact that Vermont has been able to keep its STD rate so low is a testament to the hard work and dedication of public health experts and local officials who have implemented successful prevention campaigns and early screening efforts. In addition to its ongoing commitment to education and awareness campaigns, Vermont has also adopted a comprehensive approach for STD treatment and management through primary care providers as well as specialized clinics across the state. Furthermore, more recent initiatives have successfully expanded access to preventive services such as expanded hours for testing and treatment, improving access for vulnerable populations in remote areas of the state.

The STD rate in Alaska is 756.8 cases per 100,000 people, ranking the state fifteenth in the nation. Alaska has seen a rise of STD cases overall and many experts attribute this rise to inadequate access to health care and a lack of proper sex education and prevention initiatives. All of these factors have contributed to one of the highest STD rates in all of America and highlight the urgent need for more resources and awareness in Alaska's communities.

The data reveals that over 45% of all reported cases of STDs in Arizona are chlamydia-related infections, while approximately 18% are gonorrhea-based infections. The young are disproportionately represented, with over half of all STDs reported in persons under the age of 25. The state has taken several measures to reduce the prevalence of STDs through public health campaigns and improved access to preventive care services such as regular screening and treatment for those who test positive for STDs.

The STD rate in Georgia is 826.9 cases per 100,000 people, ranking the state ninth in terms of STD prevalence throughout all of the United States. Despite many efforts to reduce these numbers, there has been little to no improvement in recent years. Recent data shows that there has been a 54% increase from a decade ago and from 2020 to 2021 there was a 17% this is largely due to a lack of access to comprehensive testing and treatment programs or simply because they have not been tested at all. Not only does this have serious health implications but it also results in a significant financial burden on Georgia’s healthcare system as well as its citizens.

Louisiana has the second-highest STD rate in the nation with 1,058 cases per 100,000 people. These high figures are likely due to a number of factors; for instance, Louisianans have been found to have lower levels of knowledge when it comes to sexual health and safe sex practices, and access to healthcare and quality educational programs in underserved communities is limited which further contributes to this growing problem.

The STD rate in Michigan is 690.6 cases per 100,000 people, ranking the state twenty-third in terms of STD prevalence throughout all of the United States. STDs such as chlamydia, gonorrhea, and syphilis are particularly prevalent in this state. The overall rate has been slowly increasing since 2011 due to inadequate funding for public health initiatives and an increase in sexual activity amongst younger individuals. To combat this issue, the state has invested in education and prevention programs to ensure that high-risk communities have access to resources to prevent the further spread of STDs across Michigan.

South Carolina has the third-highest STD rate in the United States, with 999.8 cases per 100,000 people. The most common STDs in South Carolina are gonorrhea and chlamydia, both of which disproportionately affect people aged 15-24 years. In addition to this age group, other risk factors may contribute to a higher STDs incidence. These factors include living in rural areas, being a member of minority groups, or having sex with multiple partners. The South Carolina Department of Health and Environmental Control (DHEC) has taken steps to reduce the spread of STDs by providing access to free condoms and testing at clinics across the state. By increasing awareness about protecting oneself from sexually transmitted infections, DHEC is working to reduce the number of new cases in South Carolina.
