• Blacklegged (deer) ticks, which spread Lyme disease in the Northeastern, North -Central, and mid-Atlantic United States.
• Western blacklegged ticks, which spread Lyme disease in the Pacific and Coastal regions of the United States.
• A mother infected with Lyme disease may pass it onto a fetus.

As background, ticks lay on the tops of grass and brush, clutching onto leaves with their legs and with their arms outstretched. This formation is called "questing" and allows ticks to quickly latch onto passers-by. Within two hours of biting a person's skin, the tick slowly begins to feed from the blood of its host, which can transmit the bacteria that causes Lyme disease. This tick activity generally occurs seasonally and tick bites mostly occur during the springtime.

After being infected, people with Lyme disease may develop symptoms like fever, exhaustion, headache, joint aches, and skin rash, usually three to thirty days after the tick bite. Lyme disease is characterized by a particular skin rash called erythema migrans, which is an enlarged red rash that starts at the site of the tick bite and expands outwards. The rash is a strong indicator that someone has developed or is at risk of developing Lyme disease.

In the following few months, symptoms may worsen and progress to include:

• Facial palsy (facial droop)
• Headache and neck pain
• Arthritis
• Nerve pain and numbness
• Spinal and brain inflammation
• Abnormal heart rhythm (Lyme carditis)

Most cases of Lyme disease dissipate over a few months. Lyme disease may be cured by a course of oral antibiotics, such as amoxicillin or doxycycline. Other treatments may include:

• Nerve blocking drugs for pain, such as gabapentin
• Topical ointments for rashes

People can take action to prevent Lyme disease by exercising caution when in environments with ticks. Using insect repellant and wearing long socks and protecting clothing can help prevent tick bites. Outdoor enthusiasts should regularly perform "tick checks," evaluating their skin for small ticks, especially in areas where ticks may easily burrow. Showering within two hours of returning indoors also can reduce the likelihood of developing Lyme disease.

Sexual intimacy disorders are those that cause problems with the act of sexual intercourse, such as erectile dysfunction or vulvodynia. Erectile dysfunction, the inability to get or maintain an erection hard enough for sexual intercourse, is extremely common. It affects fully half of men over 40 to some degree. It is treated with medications, devices, or surgery. Vulvodynia, burning pain in the vulva that can be made worse with sexal activity, has no known cause. It is treated with oral or topical medications.

Sexually transmitted diseases, including HIV/AIDS, herpes, gonorrhea, and chlamydia, are bacterial or viral infections that are contagious in the bodily fluids exchanged during sexual contact. Barrier methods of contraception, such as condoms, help prevent the spread of STDs. HIV is a virus that can be caught from an infected person's sexual fluids or blood. When the virus infects the body, it interferes with the immune system and causes the disease known as AIDS. There is no cure, but anti-viral medications can help people with AIDS live a long and healthy life. Herpes is also a virus found in sexual fluids, called HSV-2. It causes blisters that come and go on the genitals. There is no cure for herpes, but anti-virals can minimize outbreaks. Gonorrhea and chlamydia are both bacterial infections. They are extremely common and often have no symptoms. The most common signs of an infection are burning pain and discharge. Gonorrhea and chlamydia can be treated with medications.

Reproductive health refers to both contraception and infertility treatment. Contraceptives prevent and plan the timing of pregnancy. Some, such as a vasectomy or tubal ligation, are extremely effective at preventing pregnancy. Others, such as spermicides, are less reliable. Popular contraceptives include condoms, birth control pills, IUDs, and diaphragms. On the other side of reproductive health, infertility is the inability to carry a pregnancy to term after one year of trying. It can be due to problems in either the man or the woman, and both genders are affected equally. In total, about 15% of the population suffer from infertility. Infertility treatments include medications and surgery.

Gay and transgender people have a few specific health care needs that may sometimes fall under the sexual health umbrella. First, many LGBT people still face discrimination from healthcare providers, so providing supportive and appropriate care is an issue. Because of social attitudes surrounding sexual orientation and gender identity, many gay and transgender people struggle with their identities. Rates of depression, substance abuse, and suicide are all higher in this group. Providing mental health support and counseling to those in transition is critical. Finally, transgender patients who are undergoing gender affirmation require sensitive medical health care, including surgical and hormonal treatment.

Sexual violence can be defined as any unwanted or non-consensual sexual activity. It ranges from sexual harassment to touching to rape. It affects women more than men and is widespread: 1 in 4 women report being victims of sexual violence at the hands of a partner, and as many as 1 in 3 girls report their first sexual contact as being violent. Sexual violence has lasting physical and emotional consequences for victims, but educating both girls and boys can prevent violence. Care for those who have endured sexual violence includes counseling and mental health support, medical care, and legal support.

Sexuality is more than a reproductive requirement -- it is a form of expression and identity. Sexual health blends all these aspects of experience together and helps people lead sexually fulfilling lives.
