Can I Catch Lyme Disease Without A Tick Bite? 3 Alternative Ways Of Transmission

As awareness of Lyme disease as a public health threat increases, so does the concern around its transmission and treatment. People are starting to realise the very real danger of Lyme infection, and they have a lot of questions, especially around alternative ways Lyme disease is transmitted.

Understanding the basics of Lyme transmission, diagnosis and treatment can go a long way in helping allay fears around this increasingly common disease. Let’s break down some of the most popular questions people have about Lyme disease.

How do you catch Lyme disease?

Lyme disease is a bacterial infection caused by a corkscrew-shaped bacterium known as Borrelia burgdorferi. It is typically transmitted to humans by Ixodes ticks, also known as black-legged or deer ticks. When ticks feed on rodents, other small mammals or certain birds that are infected with Borrelia burgdorferi, the ticks themselves become infected. When a tick carrying Borrelia burgdorferi bites a human, the bacterium spreads from the tick to the bitten human, leading to Lyme disease.

Can you catch Lyme disease without a tick bite?

Although far less common than tick bites, there are some additional ways that Lyme is transmitted. Here are three alternative ways of transmission:

  1. During pregnancy

There is some evidence that Lyme disease can spread from a woman who is pregnant to her placenta, leading to potential complications. However, it appears that these problems can be avoided when the Lyme-infected mother receives antibiotic treatment for her Lyme disease. Lyme disease has not been found to be transmitted through breast milk.

  1. Through a blood transfusion

Scientists have determined that the bacteria responsible for Lyme disease can live in the blood of an actively infected person even after it has been drawn and placed in storage. Although there are no known cases of Lyme infection through a blood transfusion, a person with Lyme disease who is receiving treatment should not give blood. After antibiotic treatment has been completed, however, Lyme patients may be eligible blood donors.

  1. During sex

Scientists are very much at odds over whether Lyme disease can be transmitted sexually. While some research indicates that Lyme bacteria may be passed from person to person during sex, the Centers for Disease Control (CDC) states that there is no credible evidence supporting the claim that Lyme disease can be transmitted through sexual contact.

People being treated for Lyme disease may not be eligible for blood donation.

What should you do if you’ve been bitten by a tick?

Because tick bites are the main way that Lyme disease is transmitted, taking precautions to avoid being bitten can be your first line of defence. Some of the ways to protect yourself from ticks are:

  • Avoid wooded areas, long grass, fallen logs and other tick habitats.
  • If you’re going to be in an area where you may be exposed to ticks, dress protectively. Wear a hat, long-sleeved shirt and long trousers tucked into your socks. If you have long hair, pull it back.
  • Use tick repellent. Active ingredients that have been shown to repel ticks include DEET, picaridin and lemon eucalyptus.
  • Check for ticks periodically while outdoors, and take a shower as soon as you get home.

If you’ve been bitten by a tick, do your best to remain calm. Avoid methods like smearing Vaseline on the tick or burning it with a match, as neither of these works to remove the tick. Instead, follow these steps:

  • Take care to avoid squeezing or squashing the tick.
  • Using a tweezers with a fine point or a special tool designed to remove ticks, grasp the tick as close to your skin as possible.
  • Steadily and firmly pull the tick straight out.
  • Once the tick is out, disinfect the bite area and wash your hands thoroughly.
  • Place the tick in a small bottle or plastic bag. If it’s still alive (which is preferable for identification purposes), add a small green leaf or damp tissue to the container.
  • Explore your options for having the tick tested.
Dress protectively to avoid exposure to ticks.

 

How do you know if you have Lyme disease?

After you’ve been bitten for a tick, it’s important to watch for symptoms of Lyme disease so you can seek treatment as soon as possible. Symptoms of early Lyme disease include:

  • An expanding red rash that sometimes resembles a bullseye or target
  • Headaches and neck stiffness
  • Fever
  • Fatigue
  • Joint pain and swelling
  • Weakness or paralysis of facial muscles
  • Lightheadedness or fainting
  • Heart palpitations or chest pain

Seek medical attention immediately if you experience any or all of these symptoms of Lyme disease. The sooner the disease is diagnosed and treated, the better the chances of treating it successfully.

Knowing you’re at risk for Lyme disease can be scary, especially when the disease seems to be spreading so rapidly. But arming yourself with knowledge about Lyme disease and the different ways it’s transmitted can help you be more aware of what you need to do to protect yourself.

**Comment**

Much, much work remains to be done regarding transmission. This is one of the most honest articles I’ve read for a long time; however, due to the lack of work in this area we truly haven’t a clue on transmission prevalence regarding sexual, congenital, blood, or via other means, including other insects.  I know numerous experienced practitioners who disagree about the stance this article takes that it can’t be spread via breast milk.  Again, until more transparent work is done, all we have are clinical case studies.

For far too long authorities have dismissed these possibilities with a wave of the hand, while experienced researchers have stated since the 80’s that the black legged tick is not the sole perp:  https://madisonarealymesupportgroup.com/2019/05/24/microbiology-professor-im-convinced-lyme-disease-is-transmittable-from-person-to-person/

“I AM CONVINCED THAT LYME DISEASE IS TRANSMITTABLE FROM PERSON TO PERSON.” Lida Mattman, PhD.

Well, it doesn’t get any clearer than that.

When you consider the insidious conflicts of interest within the CDC and the fact there has been biowarfare experimentation done on ticks for decades, one begins to understand why the CDC has dismissed anything that might bring them under the Eye of Mordor.

CZECHS RECORD MOST TICK-BORNE ENCEPHALITIS (TBE) CASES IN ENTIRE EU

24-05-2019

The Czech Republic recorded the highest number of tick-borne encephalitis (TBE) cases in the EU last year. In the whole of Europe, only Russia recorded more cases of the potentially deadly disease.

There were 712 recorded TBE cases in the country last year, the highest number since 2011, a Czech member of the International Scientific Working Group on TBE (ISW-TBE) said in a press release on Thursday.

Only about one quarter of inhabitants of the Czech Republic are vaccinated against TBE, a low percentage compared to other EU countries. Within the bloc, the second-highest number of TBE cases was recorded in Germany, which has a population eight times larger.

Encephalitis patients suffer from fever, headache, aching joints and muscles. It can develop into meningitis.

Septic Shock Caused by Rocky Mountain Spotted Fever in a Suburban Texas Patient with Pet Dog Exposure: A Case Report

Abstract

Patient: Female, 45

Final Diagnosis: Rocky mountain spotted fever

Symptoms: Altered mental state • ataxia • dyspnea • fever • headache

Objective:

Unusual clinical course

Background:

Rocky Mountain spotted fever (RMSF) is associated with high mortality and requires prompt identification and treatment to ensure better outcomes.

Case Report:

We describe an advanced case of RMSF in a 45-year-old female patient with pet dog exposure who presented with altered mental status, dyspnea, and ataxia progressing to septic shock and acute hypoxic respiratory failure requiring intubation and mechanical ventilation.

Conclusions:

This case illustrates the importance of keeping RMSF in the differential diagnosis in patient populations outside of the usual geographic areas of incidence in the appropriate clinical setting.

**Comment**

This is what can happen when diagnosis is delayed.

This woman that lived in the suburbs had a 7-day history of fevers associated with headache, arthralgias, nausea, fatigue, and neck pain, but did NOT have the tell-tale blotchy RMSF rash.

Two days later, she worsened with confusion, combativeness, dyspnea, and ataxia. She got multiple recent bug bites from her pet dogs sleeping in her bed. The dogs were not up to date on flea and tick medication but were healthy and showed no sign of illness.
  • Rule #1:  Do NOT sleep with pets.  The risk is too great.
  • Rule #2:  If you choose to have pets, make sure you treat them if they go outdoors.  The risk is too great.
  • Rule #3:  Doctors need to start treating this plague with the respect it deserves and frankly should keep it in the back of their minds AT ALL TIMES.
Positive findings were R. typhi IgM 1: 1024 (normal <1: 64), R. Rickettsii IgM 1: 1024 (normal <1: 64), IgG 1: 128 (normal <1: 64), and echovirus Ab 1: 80 titer (normal <1: 80). The Rickettsial titers were repeated for possible cross-reactivity and R. typhi antibodies were noted to be negative (<1: 64).
Although R.typhi was ruled out due to cross-reactivity, I believe we will start seeing more of this strain in the future.
The patient improved on doxycycline, the drug of choice for RMSF and was discharged.
Why isn’t there a full-out media blitz on this like there was on Zika?

Going Outside? Watch Out For Asian Longhorned Tick Now in Kentucky

Going outside? Watch out for unusual tick found in Eastern Kentucky

By WYMT News Staff

MARTIN COUNTY, KY. (WAVE) – It’s Memorial Day weekend and more people will head outside as the summer season kicks off. While you’re out having fun, be sure to keep an eye out for a tick that is new to the area.

This year’s tick season is different in Kentucky because a new tick has popped up in our area.

The University of Kentucky College of Agriculture, Food and Environment has received more calls about seeing ticks, but reports that incidents of tick-borne diseases in the state are very low.

People still need to use precautions because ticks are out there. They’re looking to suck blood three times in their lives in order to reproduce. This year’s tick season is different in Kentucky because a new tick has popped up in our area.

“The most common ticks we have are the Lone Star Ticks and the American Dog Tick,” Spencer County Agriculture agent Bryce Roberts said. “The new one we found is the Asian Longhorned Tick.”

Roberts said the Asian Longhorned Tick was found in Eastern Kentucky, in Martin County.

It’s very concerning because of the diseases they do carry,” Roberts said.

New ticks bring new diseases. Before or when someone gets a tick disease, they see epidemiologist Dr. Paul Schulz.

“The two we encounter the most are Ehrlichia and Rocky Mountain Spotted Fever,” Schulz said.

Schulz said the infectious disease department at Norton Healthcare found its first tick-borne disease of the year in March, a sign that tick season could be starting early.

“(In) well over 50 percent of diagnosed infections, the patient didn’t know they had tick exposure,” Schulz said.

People often don’t see or feel when a tick is biting them. However, there are ways to protect yourself and your summer experience: Cover up as much of your skin as you can, use a spray with DEET, avoid overgrown wooded areas, check yourself and your children every night.

In China and Japan, it transmits the severe fever with thrombocytopenia syndrome virus (SFTSV), which causes a human hemorrhagic fever (2), and Rickettsia japonica, which causes Japanese spotted fever (3). Studies in Asia identified ticks infected with various species of Anaplasma, Babesia, Borrelia, Ehrlichia, and Rickettsia, and all of these pathogen groups circulate zoonotically in the United States (4,5). In addition, parthenogenetic reproduction, a biologic characteristic of this species, allows a single introduced female tick to generate progeny without mating, thus resulting in massive host infestations.

 

Authorities have been relatively mum on what this tick transmits and I’ve had to dig to find it.  So far there are no noted human illnesses caused by this tick in the U.S., but the ones listed above have occurred other countries.  Do they really think this tick isn’t going to acquire disease and transmit here?  Maybe in an alternative reality, but then again, the CDC lives in an alternative reality.

 

 

 

 

 

Ehrlichia Strain Isolated From a Minnesota Tick – Frequently Lethal in Mice & Hamsters

https://www.ncbi.nlm.nih.gov/pubmed/31076433/

2019 May 10. pii: AEM.00866-19. doi: 10.1128/AEM.00866-19. [Epub ahead of print]

Characterization and genetic transformation of an Ehrlichia isolated from a Minnesota tick.

Abstract

Ehrlichia muris subsp. eauclairensis is recognized as the etiological agent of human ehrlichiosis in Minnesota and Wisconsin. We describe the culture isolation of this organism from a field-collected tick and detail its relationship to other species of Ehrlichia. The isolate could be grown in a variety of cultured cell lines and was effectively transmitted between Ixodes scapularis ticks and rodents, with PCR and microscopy demonstrating a broad pattern of dissemination in arthropod and mammalian tissues. Conversely, Amblyomma americanum ticks were not susceptible to infection by the Ehrlichia. Histologic sections further revealed that the wild-type isolate was highly virulent for mice and hamsters, causing severe systemic disease that was frequently lethal. A Himar1 transposase system was used to create mCherry and mKate-expressing EmCRT mutants, which retained the ability to infect rodents and ticks.

Importance: Ehrlichioses are zoonotic diseases caused by intracellular bacteria that are transmitted by ixodid ticks. Here we report the culture isolation of bacteria which are closely related to, or the same as the Ehrlichia muris subsp. eauclairensis, a recently recognized human pathogen. EmCRT, obtained from a tick removed from deer at Camp Ripley, Minnesota, is the second isolate of this subspecies described, and is distinctive in that it was cultured directly from a field-collected tick. The isolate’s cellular tropism, pathogenic changes caused in rodent tissues, and tick transmission to and from rodents are detailed in this study. We also describe the genetic mutants created from the EmCRT isolate, which are valuable tools for the further study of this intracellular pathogen.

OTHER MODES OF TRANSMISSION

Ehrlichia chaffeensis has been shown to survive for over a week in refrigerated blood. Therefore these bacteria may present a risk for transmission through blood transfusion and organ donation. It has also been suggested that ehrlichiosis can be transmitted from mother to child, and through direct contact with slaughtered deer. (14, 15)
