What is rickettsial infection?

Have you ever heard of rickettsial infection? If not, don’t worry – it’s not something you come across every day. But if your curiosity has gotten the best of you and now you’re wondering what this fancy medical term means, then strap in for a wild ride.

Let’s Start with the Basics

Rickettsial infections are caused by bacteria from the Rickettsiae genus. These little guys like to set up shop inside cells and wreak havoc on various organs throughout our bodies. There are several different types of rickettsial bacteria that can cause infections, each with their own unique symptoms and quirks.

The Symptoms

Before we delve into these specific bacteria though, let’s talk about what kind of symptoms rickettsial infections usually present with:

  • Fever (and boy do they bring the heat)
  • Headache
  • Muscle pain (think flu-like symptoms)
  • Rash
  • Gastrointestinal issues (nausea/vomiting/diarrhea)

These might seem pretty standard, but trust me when I say that rickettsial infections are anything but ordinary.

Types of Rickettisa Bacteria

Alrighty then – now that we have some background info under our belts let’s dive into the individual bacterial baddies themselves.

Rocky Mountain Spotted Fever: When You Just Need to Escape City Life

Rocky Mountain spotted fever (RMSF) might sound like a vacation spot for people who hate crowds and noise pollution, but unfortunately it couldn’t be further from an escape. RMSF is actually one of the more severe rickttesal diseases out there due to its potential involvement with vital organ systems such as heart & blood vessels.

How does it spread?

This particular bacterium is most commonly transmitted through tick bites during outdoor activities such as hiking, camping or enjoying the great outdoors in general.


RMSF starts out with a fever and headache but quickly progresses to include:

  • Rash (that can start on palms/soles)
  • Gastrointestinal issues
  • Joint pain
  • Cardiovascular collapse can occur, so watch out!

Scrub Typhus: AKA The Mite-y Enemy You Never Knew You Had

Scrub typhus is another rickttesal disease that likes to make things difficult for your immune system.

How does it spread?

This little bugger makes its home amongst mites which live in regions where humidty exceeds 70% of average… hence why heavy monsoons increase scrub typhus patterns.Besides that, you could pick up a case via travelling through sweltering areas as well. Good thing everyone’s vacation plans have been nullified right about now huh?!


The early symptoms are usually present after around ten days from exposure & involve :
– Fever accompanied by chills
– Severe headache
– Muscle pains and stiffness throughout the body

Scrubs aren’t all fun & Games.. Here’s what happens next:

As usual, along come severe problems particularly involving septic shock-like states(almost like bacterial second-hand smoke)like :

  • Lung failure making you short of breath 🌬️
  • Brain inflammation leading upto confusions 😵
  • Abnormal blood clotting 🩸

Ehrlichiosis : Not just Pimple-Poppin’!

Now I would tell you not to be grossed out by how this one spreads( they are found inside ticks too), but I won’t judge if you still think it’s nasty Some people will do anything for their research! Please try & avoid imagining those little critters crawling over yourself; that stuff gives me nightmares!

Infection Cycle

Ehrlichiosis causes the flattening of red & white blood cells which leads to accumulation inside vessels, creating a cycle that adversely affects human anticoagulation systems. It’s really bad news when it goes unnoticed in people with weakened systems – like those under medication for cancer or otherwise immuno-compromised.


The early symptoms and thus chance of getting tested are similar- with fever being prominent alongwith

  • Fatigue (😴)
  • Muscle Aches(💪)
  • Headache(🧠)

Then things may turn extremely unpleasant:

  • Respiratory distress 😰
  • Confusion/Depression/Sleep Disruption 💤
  • Bleeding&Increasing bruising eventually leading to death; but atleast there’s usually rash!(#weakattemptatjokes)

So how do we Deal With these Little Jerks?

Diagnosis and Treatment Methods

It should be noted our medical professionals have honed their procedures considerably after years of trials and several errors(gotta love progress!) Early detection is key because rickettsial infections can mimic other diseases with mild similarities in symptoms.
Reliable diagnosis could be done thanks due improved staining techniques aimed at better visualization of various microorganisms,it doesn’t even resemble sorcery anymore!Be prepared for invasive specimen-sampling though( lets not go into details!). The most common method currently employed is via antibody identification test(named IFA) which yields results ranging from specific bacteria all the way up to genus level.

Treating Rickettsial Infections takes time – Full disclosure: There isn’t an instant cure-all solution available as yet.The course starts out cautiously and then progresses either with tablets/or administered injections.This says nothing about the antibiotics patients will need if superimposed by other complicated infections.Phewy!

Still it holds true that prompt diagnosis allows doctors to act right away, giving them more control over reducing disease progression and minimizing symptoms from getting too out of control.

Prevention Strategies: You’re Welcome 🙋🏽

  • Tick/Mite avoidance
  • Avoid reserved/ heavily vegetation-laden spaces
  • Applying repellents with decent permethrin concentration, despite odours.
  • Clothing:
    • Wearing long & Loose fit shirts and pants, tucked inside the clothes while hiking or doing ANY activity that involves outdoor exploration will keep you safe!
    • Footwear should be covered so as to ensure no open areas for ticks/mites to zero in on your feet.

Keeping this little guide handy could do wonders for spreading more awareness about rickettsial infections! It’s remarkable how details about these rare medical terms are usually kept locked away like buried treasure beneath pages of scientific journals. Now that I’ve [pitched] it all..please try not rooting against us when people go ahead digging up various diseases due our increased ‘connectivity’ with wildlife during an ongoing PANDEMIC!
