• 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.

Mononucleosis happens in three stages:

During the initial stage, those with mono may experience few symptoms as EBV replicates in the body. Symptoms such as headaches and body aches are often misattributed to allergies or stress. People with mono may continue performing their daily activities and attending school, leading to increased transmission of the virus to others. The initial stage lasts for about five to fourteen days.

During the acute stage, mono symptoms intensify and may include the enlargement of the spleen, a sore throat, fatigue, liver issues, and skin rashes. The mono infection is at its worst in this stage.

Lastly, the convalescent stage is when recovery begins. This period of healing can last from two to six months.

Mono can be detected by a physical exam; physicians can diagnose mono by checking for inflamed lymph nodes, tonsils, or spleens. Blood antibody tests may also help diagnose mono by revealing antibodies in the blood that were formed as a response to the Epstein-Barr virus. Elevated levels of white blood cells can also suggest that a patient has mono.

There are no medications specifically for mono or the Epstein-Barr virus, and patients are advised to rest and avoid strenuous exercise. Drinking plenty of fluids, eating a healthy diet, and taking anti-inflammatory ibuprofen (motrin) may also help people who are afflicted with mono feel better.

People with mono should take precautions to avoid spreading the condition to others. They can prevent infection by not sharing glasses, food, and utensils with others until they fully recover.
