CDC Warning: Rocky Mountain Spotted Fever Cases Rise Near Border

The Centers for Disease Control and Prevention (CDC) has issued a warning regarding a recent increase in Rocky Mountain spotted fever (RMSF) cases near the U.S.-Mexico border. This serious bacterial illness, transmitted through the bite of infected ticks, requires immediate medical attention. Understanding the risks and preventative measures is crucial for residents and travelers in affected areas.

Understanding Rocky Mountain Spotted Fever

Rocky Mountain spotted fever is a potentially life-threatening illness caused by the bacterium Rickettsia rickettsii. While the name suggests a geographic limitation, RMSF cases are reported across the United States, with higher incidences in certain regions, including areas bordering Mexico.

Symptoms of RMSF

Symptoms typically appear within two to fourteen days after a tick bite and can include:

• Fever: Often high and accompanied by chills.
• Headache: Severe and persistent.
• Muscle pain: Significant aches and pains in the body.
• Rash: A characteristic rash often appears 2-5 days after the fever begins. It typically starts on the wrists and ankles, spreading to the palms and soles. Important Note: Not everyone with RMSF develops a rash.

If you experience these symptoms, particularly after spending time in tick-infested areas, seek immediate medical attention. Early diagnosis and treatment are critical for a positive outcome.

The Border Region Risk

The CDC's warning highlights an uptick in RMSF cases near the U.S.-Mexico border. This increase might be attributed to several factors, including:

• Tick population density: Certain environmental conditions in border regions may be favorable for tick populations.
• Increased human-tick interaction: Outdoor activities and proximity to natural habitats increase the risk of tick bites.
• Limited awareness: Lack of awareness about RMSF and preventative measures contributes to higher infection rates.

Protecting Yourself from RMSF

Prevention is key to avoiding RMSF. Here are some practical steps you can take:

Tick Bite Prevention:

• Wear protective clothing: When venturing outdoors in tick-infested areas, wear long sleeves, long pants, and closed-toe shoes. Tuck your pants into your socks to prevent ticks from crawling up your legs.
• Use insect repellent: Apply EPA-registered insect repellent containing DEET, picaridin, IR3535, or oil of lemon eucalyptus to exposed skin.
• Check for ticks regularly: Perform thorough body checks after spending time outdoors, paying close attention to areas like the scalp, armpits, groin, and behind the knees.
• Remove ticks properly: If you find an attached tick, remove it carefully with fine-tipped tweezers. Grasp the tick close to the skin and pull gently upward. Clean the bite area with soap and water.
• Treat your yard: Reduce tick habitats by regularly mowing the lawn, removing leaf litter, and keeping grass trimmed.

What to Do if You're Bitten

If you suspect a tick bite, monitor yourself for symptoms of RMSF. Early diagnosis and treatment with antibiotics are crucial. Do not delay seeking medical attention if you experience any symptoms.

Conclusion: Staying Safe Near the Border

The CDC's warning serves as a critical reminder of the ongoing risk of Rocky Mountain spotted fever, particularly in border regions. By understanding the risks and implementing preventative measures, you can significantly reduce your chances of contracting this serious illness. Stay informed, take precautions, and prioritize your health. If you have any concerns, consult your physician or a public health official.
