Babesia Sweats and Coinfection: Why Symptoms Last Longer
Babesia sweats are a common symptom — but they are only one part of the picture. When patients have both Babesia and Lyme disease, illness is often more severe and longer lasting. :contentReference[oaicite:0]{index=0}
A landmark study found that 50% of coinfected patients remained symptomatic for 3 months or more, compared to just 4% of those with Lyme disease alone.
Recognizing the connection between night sweats and Babesia coinfection can change the course of care.
Babesia Sweats and Other Symptoms
In a study by Krause and colleagues, 46% of Babesia patients reported sweats — but 42% did not, meaning absence of sweats does not rule out infection.
Other common symptoms included:
- Fatigue (81%)
- Headaches (77%)
- Fever (58%)
- Chills (42%)
- Muscle aches (38%)
Sweats are not unique to Babesia and can also occur in Lyme disease and anaplasmosis.
Why Coinfection Makes Patients Sicker
Patients with both Lyme disease and Babesia tend to have more symptoms and a more prolonged illness.
In the same study:
- 50% of coinfected patients were symptomatic for ≥3 months
- Only 4% of Lyme-only patients had prolonged symptoms
Coinfected patients also had higher rates of detectable spirochetal DNA and were less likely to be asymptomatic.
These findings suggest that coinfection can amplify symptom burden and delay recovery.
Delayed Diagnosis Is Common
Babesia is frequently missed.
In the study, none of the patients initially received Babesia treatment, reflecting delays in recognition.
Even patients without obvious immune compromise can develop significant illness.
How Common Is Babesia Coinfection?
Up to 40% of patients with Lyme disease may have Babesia coinfection in some regions.
Cases are increasing, particularly in the Northeastern United States.
Babesia should be considered in patients with atypical Lyme presentations or incomplete response to treatment.
Testing Challenges
Babesia can be difficult to detect.
- Blood smears may miss infection
- Serologic and PCR testing may be negative in a significant proportion of patients
Clinical judgment remains an important part of diagnosis.
Treatment Differs from Lyme Disease
Babesia is a parasite, not a bacterium.
This distinction is critical because standard Lyme antibiotics do not treat Babesia.
Typical therapy includes:
- Atovaquone + azithromycin
- Alternative: clindamycin + quinine
Patients with coinfection often require treatment for both Lyme disease and Babesia.
Babesia Sweats Are Not the Only Clue
While babesia sweats can be helpful diagnostically, they are not reliable on their own.
When night sweats are accompanied by:
- Air hunger
- Severe fatigue
- Temperature dysregulation
Babesia coinfection may be worth considering.
Clinical Takeaway
Babesia coinfection is associated with more severe and longer-lasting illness.
- Half of coinfected patients remain symptomatic for 3+ months
- Absence of sweats does not rule out Babesia
- Testing may miss infection
- Treatment requires antiparasitic therapy in addition to Lyme antibiotics
Frequently Asked Questions
Are babesia sweats common?
About 46% of patients report sweats, but nearly as many do not — so absence of sweats does not exclude infection.
How is coinfection different from Lyme alone?
Coinfected patients tend to be sicker for longer and have more persistent symptoms.
Why doesn’t Lyme treatment work for Babesia?
Babesia is a parasite and requires different medications than bacterial Lyme disease.

My husband was diagnosed with Lyme disease about 3 years ago…….although a bulls eye was never noticed on him, we feel he had it for considerable time before being diagnosed. He had one month of antibiotics and did well for about 4 months……He has had occasional night sweats and high debilitating fevers. Now he is dealing with body sweats throughout the day. His physician did a repeat testing for Lyme and it was negative. I am at my wits end as to how to help him….soo many doctors insist he is cured and he is not! I notice mood swings….memory loss…concentration issues….At 71 he still works a full 60 hours per week, but I do not know how he does it…..he was tested for coinfections and the test also was negative…..where do we turn?
Doctors are divided over whether to use clinical judgement when testing negative. You may need to consider treatment for Babesia given the sweats. You should also rule out other illnesses.
Same thing happened to me. My Lyme doctor told me I was cured, but I was having crazy heat flashes in the middle of the day, exhaustion, stiff neck, etc. I contacted dr. Zhang in nyc and went on their herbal protocol and it changed my life for the better. They told me immediately that I had Babesiosis and they could tell because a key symptom is it does not allow you to regulate your body temperature! You can do one in person consult with him or his assistant Phyllis and he/she will put him on an herbal
Protocol that costs about 300-400 a month and he will be cured within a year. Only hard part is the diet they put you on, but it’s worth having your health back. If you don’t want to go to nyc then you can also get the book “healing Lyme” by Stephen Buhner and it tells you some of the herbs that Zhang would recommend and he can order them online and self medicate. That will work too, but the diet actually speeds up the process and zhang has pharma grade herbs so I would go that route. Last piece of advice is make sure his iron count is good if he goes on the herbs..the herbs need the iron to kill the Babesiosis, I was anemic so it took a lot of extra time until I found that out..Babesiosis loves to eat the iron in the body too, so you need to take liquid supplements while killing it! That’s it..good luck and god bless.
Try to find a llmd doctor that will treat your husband for his symptoms, not blood test results-you could still have lyme desease, babasia ,bartonella with negative blood test results
It would be wonderful if you had a practice in maryland
Where do you live in Maryland?
I went to the University of Minnesota and got 2500 dollars in blood tests that all came back negative. I am at my wits end with this. Pain, Insomnia, sweats, chronic fatigue etc…I messaged my doctor about the results and asked if I should get an appointment as I had returning headaches. He told me he sent me to the specialists because he is unable to help me and to find another doctor. What???I’ve seen everyone already, at great cost to my family for the last 16 months. Tested CDC positive for Lyme. I write this as I didn’t sleep at all tonight, not uncommon anymore, pain and sweats were bad so I gave up. Is there anyone in MN that gets this?? Starting to give up but I can’t. I have to keep going for my kids. Feel so sick. Financially, emotionally and physically can’t keep this up anymore!
I grew up in Minnesota. I realize how hard it include a doctor with experience treating tick borne diseases. I have people who fly to New York reflecting the difficulty finding a doctor. You should work with local support groups or leaders to find a doctor. You may also contact the Lyme Disease Association, ILADS, or Global Lyme Alliance websites for names.
Hi Cathy, perhaps this is far too late as you commented a year+ ago…. my husband has been having the same issues and we have spent tens of thousands of dollars trying to figure out what is wrong with him. He finally went (per recommendation….. after 6+ years of issues) to Restorative Health Solutions in Edina and saw Dr . Warren. He performed a whole panel of very extensive testing for infections and co-infections. We FINALLY got an answer…. Babesia. We are waiting on the co-infection result, but suspected Lyme as well and we have an appointment this Friday…. which can’t come soon enough. In the last week the symptoms have worsened with extreme flushing/sweats during the day accompanied by chills and severe headache.
We recommended a friend to Dr. Warren as well and she has a phone consult on Friday. This has been the most frustrating, anxiety ridden journey we could have ever embarked on. It’s suspected he’s had it since he was bit in 2011. The last 3.5 years have been hell, and progressively worsening— to the point of questioning if a career and residence change is needed.
I do hope you see this and can seek some additional testing at this clinic. The Dr was very committed to finding the cause, but started with the “base” testing…. it was $1450. If additional tests were needed he would do them, but believes in only doing what is necessary to keep costs down for patients.
I often find Babesia to be the missing link in my patients who are finding it difficult to get better with treatment for other tick-borne illnesses. Commonly used antibiotics like doxycycline and amoxicillin are not effective for Babesia.
Am wondering if Cathy found the help she so much needed??

Homeopathy may help. Search for Lyme and Homeopathy and go from there.
No, it won’t. That’s a fantasy that keeps people from pursuing serious but challenging treatment.
Lymedisease.org has a Physician Finder link. You can just type your location to find an LLMD nearest to you. They also have free CME courses for physicians and nurses (AND patients!) to better educate medical professionals on current research and treatments. A lot has changed since I was first diagnosed in 2013! I am currently taking advantage of the free CME courses for my license renewal.
I was just diagnosed with Lyme but know nothing about it. Saw the red dot but honestly , if that’s the beginning why have I been getting worse since last year. Can they tell you definitively what stage it is cause I have them all
Do yourself a favor and find a REAL doctor, even remotely. I’ve struggled with it for nearly a decade…
Having almost 100 symptoms(of Lymes disease)for 3 years, the newest symptom of a few months is sweating under the soles of my feet, sweating following drinking a hot drink(also chills and touch) Imagine still no diagnosis and absolutely NOBODY taking me seriously, I mean what has to happen before somebody will DIE
I have babesia, Rocky mountain spotted and lymes for 2 years, the antibiotics are not working, I don’t have any idea what to do. The antibiotics have killed my immune system to where I can’t go out without catching something. I’m at wits end.
I am sorry to hear you are having a problems. I have patients who have benefited from a second Lyme disease opinion doctors vary in their approaches.
