Bitten by Bugs? Protect yourself from Scrub Typhus with These Tests!

Scrub typhus is a bacterial infection which is transmitted through tiny mites carrying the Orientia tsutsugamushi bacteria. This disease is prevalent among people worldwide and more so in the rural tropical regions of Asia, Pacific Islands and Northern Australia. It can be fatal if not treated promptly, as its case fatality rate (CFR) in India falls between 1% and 34% based on the affected region or organ.

A better understanding of scrub typhus disease will help in early identification and, therefore, minimise possible complications or fatalities. Here are the details of the disease, including the signs, origins, diagnostic methods, and cures, to guide you in avoiding this lethal disease.

Signs & Symptoms of Scrub Typhus

Scrub typhus symptoms typically appear within 10 days following a mite bite. The illness can lead to different symptoms and make you feel quite ill. Understanding these signs at an early stage can assist in getting prompt medical attention.

• Fever
• Skin Sores 
• Rash
• Severe Headache
• Body Aches or Muscle pain

Causes of Scrub Typhus

• Tiny Mites: It is caused by a bacterium transmitted through the bites of small mites that are common in regions with extensive bushes.
• Orientia Tsutsugamushi: This bacterium is known to be the major cause of the disease.
• Geographical Spread: It is typically present across Asia, the Pacific region and northern regions of Australia.
• Environmental Factors: People living or working in rural or forested regions are at higher risk.
• Seasonal Occurrence: Scrub Typhus is more frequent during the wet season as mites are highly active in moist atmospheres.

Scrub Typhus Diagnosis

Prompt diagnosis will help in the early treatment of the scrub typhus disease and ensure rapid recovery. To diagnose scrub typhus, doctors perform a series of tests and check the symptoms the patient is displaying. Here’s how they do it:

• Physical Examination: Health experts search for signs unique to the disease, such as the eschar.
• Blood Tests: Serological tests can reveal the presence of antibodies or bacteria in one’s system.
• PCR Tests: PCR tests can detect the presence of the bacterium’s DNA.
• Serological Tests: These tests determine the presence of antibodies to the bacteria in the individual's bloodstream.
• Clinical Symptoms: A diagnosis is usually based on characteristic signs and symptoms and a history of possible contact with the organism.

Management & Treatment of Scrub Typhus

Scrub typhus treatment typically includes antibiotics and care to support the patient’s health. Here are the basic steps suggested by healthcare practitioners to recover from scrub typhus.

• Antibiotics: Doxycycline and azithromycin are commonly used antibiotics, which doctors often prescribe when treating respiratory infections. Healthcare professionals typically give azithromycin to children and pregnant women.
• Rest: Adequate rest is essential to help the body fight the infection.
• Hydration: Staying hydrated is important, especially if fever causes sweating.
• Monitoring: Watch for complications like respiratory issues or organ failure.
• Follow-up: Regular follow-ups with the doctor ensure the infection is fully treated.

Precautions for Scrub Typhus

Taking precautions can help you avoid scrub typhus disease. Here are some practical tips:

• Wear Protective Clothes: Long sleeves and full pants can protect your skin from mite bites.
• Use Insect Repellent: Apply repellent to exposed skin and clothing.
• Steer Clear of Infested Zones: Strive to avoid places recognised for having a substantial population of mites.
• Maintain Cleanliness: Keep living and working environments clean to discourage mites.
• Look for Mites: Often examine your skin and clothes for mites if you are often outdoors.

Conclusion

Scrub typhus disease is life-threatening, but it is easily avoidable with the right information and precautions. While it is nearly impossible to eliminate mites from one’s environment, there are several steps an individual can take to reduce the risk of encountering these insects.

Awareness of the disease alongside preventive steps can help you live a healthy life, free from scrub typhus.
