Could My Dad Catch Mono From Me?

6/20/2025, 2:30:34 AMMale25-34

Recently, I (28-year-old female) received a positive diagnosis for mononucleosis. Just yesterday, while sipping on a can of sparkling water, I left it in the fridge to enjoy later. This evening, my father (64-year-old male) approached me, expressing that he suspected it could be his drink and took a sip from it. The can had been chilling in the fridge for just over a day. Now, I'm concerned that he might contract mono from me, but I'm holding out hope that he will be fine. I feel a bit careless for leaving my drink unattended, but I didn't anticipate anyone would confuse it with theirs.

It's understandable to be concerned about the possibility of transmitting mononucleosis (often caused by the Epstein-Barr virus) to your father, especially after he sipped from your drink. Here’s a breakdown of the situation and what you can do next.

Main Points

  1. Transmission Risk: Mononucleosis is primarily spread through saliva, but it can also be transmitted through shared items like utensils or drinks.
  2. Time Frame for Contagion: The virus can remain in a person’s saliva for weeks to months even after symptoms resolve. However, the likelihood of transmission from a one-time sip is relatively low.

Explanation

Mononucleosis is often referred to as "the kissing disease" because it's commonly transmitted via saliva. Since your father only took a single sip from the can, the risk of him contracting mono is lower than if you had directly shared something like a fork or kissed him. Nonetheless, there is still a possibility, albeit small, depending on factors like how much virus was in your saliva and the immune health of your father.

Next Steps

  1. Monitor Symptoms: Watch for symptoms in both you and your father over the next few weeks. Common signs of mono include extreme fatigue, sore throat, swollen lymph nodes, and fever.

  2. Encourage Hygiene Practices: To reduce any potential risk:

    • Avoid sharing personal items like drinks, utensils, and towels for the time being.
    • Ensure both of you practice good hand hygiene, washing hands frequently with soap and water.
  3. Reassure Your Father: Talk to him about your concerns. Most people exposed to the virus do not develop symptoms, especially if they are older and have a robust immune system.

If he does develop any significant symptoms, it may be beneficial to consult a healthcare professional for further advice. Feel free to reach out if you have more questions or need support during this time!

Inability to Sneeze: Potential Neural Communication Issues

Hello. I’m seeking assistance to comprehend my situation and explore possible remedies. I’m a 25-year-old male working as a software engineer and currently not taking any medications. For the last two years, I have experienced an inability to sneeze. This issue first arose following two significant incidents involving exposure to neurotoxic substances, which led to a variety of neurological symptoms. 1) **Vitamin B6 Toxicity**: Over a span of 4-6 weeks, I received seven intramuscular injections of a B-complex vitamin, each containing 100mg of Vitamin B6 in the pyridoxine form. Shortly after beginning these injections, my health rapidly declined, and numerous symptoms emerged. Research has identified pyridoxine as potentially neurotoxic, with recent documentaries and studies — particularly from the Australian community — raising awareness about this condition. In response, Australia’s Therapeutic Goods Administration (TGA) has taken steps to restrict the sale of B6 supplements and to lower their permissible amounts. For more insight into the seriousness of this issue, you can find several informative short documentaries on the ABC News YouTube channel. 2) **Insecticide Exposure**: While undergoing the B6 treatment, I also encountered a concerning situation where I inhaled toxic insecticide fumes. Not realizing the danger due to nasal congestion from a minor illness, I sprayed a considerable amount of insecticide in my room. It was only after I started coughing that I realized I had been breathing in these harmful fumes. It occurred late at night when I was already feeling unwell, and I opted to go to sleep shortly afterward. Both incidents occurred in September to October of 2021, after which I began to experience an alarming array of around twenty symptoms affecting my sensory, motor, and autonomic nervous systems. I developed severe numbness and tingling in various parts of my body, involuntary muscle movements, ataxia, facial numbness accompanied by a loss of muscle volume in my face due to nerve damage, and symptoms that resembled diabetes such as excessive thirst and fatigue post-meals. Other issues included rapid heart rate, skin lesions, an inability to sweat, extreme muscle weakness, and significant psychological symptoms, including emotional numbness and anhedonia. Virtually every area involving nerves seemed to be impacted. Now, 18 months later, I’ve made considerable progress, with most of the symptoms easing, but I still struggle with the inability to sneeze. Recently, after experiencing a flu, I noticed that my body failed to sneeze about 90% of the time. I feel the urge to sneeze starting deep in my lungs, traveling to the tip of my nose, yet it rarely culminates in an actual sneeze. Instead, I feel pressure released in alternative ways, sometimes sensed as pressure in my head, and occasionally, I experience tears running from my eyes and nose when the sneezing sensation arises, yet no sneeze follows. Despite waiting a year and a half for recovery and seeing improvements in my larger nerves, these specific bodily functions remain unresolved. A recent electromyography (EMG) and nerve conduction study (NCS) conducted two weeks ago returned normal results, which aligned with my awareness of the recovery in my larger nerves and muscles during this period. Through my research, I’ve discovered that the trigeminal and cranial nerves play a crucial role in initiating a sneeze, suggesting the presence of a signaling issue. I would greatly appreciate guidance on this matter.

Lower Lip Abscess in a Young Child

My four-year-old is dealing with a lower lip abscess. What began as a small crater on his lip last Sunday rapidly progressed to a pus-filled lesion by Monday night. By Wednesday evening, we managed to see a pediatrician who admitted him for intravenous antibiotic therapy. Since being hospitalized on Wednesday night, he has been receiving Sulvacil through an IV. A general surgeon evaluated him yesterday but chose not to perform an incision for drainage, stating that managing a lip wound would be quite challenging at his age. Currently, I'm feeling uncertain about the progress of his condition, as the abscess appears to still contain pus. It seems to swell and then reduce in size only to fill up again. Despite this, my child remains lively and has a good appetite, though he does experience discomfort when trying to chew. I’m left wondering if we are observing any tangible improvement, or if it might still be too soon to judge the situation?

Persistent Vomiting and Confounding Endoscopy Findings

I'm struggling to articulate my situation adequately, but I'll share everything and hope not to overlook any details. I'm 16 years old, standing at 5 feet 7 inches tall, and weighing 140 pounds. My blood tests have returned normal results, although I do have slightly low vitamin D levels, and my stool samples have come back clear. My current medication regimen includes 30 mg of Vyvanse, 20 mg of propranolol taken twice daily, 300 mg of gabapentin at night and 150 mg in the morning, and I recently began taking 25 mg of amitriptyline a week ago. Since I was about four or five, I’ve experienced unusual digestive issues, such as diarrhea, stomach cramps, constipation, and acid reflux, with the most alarming symptom being unexplained vomiting. Daily abdominal cramps and constipation are common for me, and surprisingly, these symptoms don’t seem to be influenced by my diet or activities. Around the age of five, I started to vomit inexplicably, particularly during times of excitement like the Super Bowl, birthday celebrations, or, most notably, vacations. When I turned 12, my condition worsened significantly after contracting COVID-19. I started experiencing dry heaves or vomiting almost every morning, which led to frequent school absences, severe migraines concentrated mostly on the left side of my forehead, and worsening stomach troubles. Living in Washington, I consulted numerous specialists at Swedish, including both an allergist and a gastroenterologist. The allergist suspected mast cell disease and prescribed Cromolyn, which unfortunately did not provide any relief. The gastroenterologist suggested that I had an issue related to my "lizard brain" and advised me to “find a hobby.” I also visited a cardiologist due to low blood pressure, where I was diagnosed with neurocardiogenic syncope. Recently, I convinced my general practitioner to refer me to a children’s hospital, where I underwent an endoscopy. To my surprise, the procedure revealed food remnants in my stomach despite having fasted for over 11 hours beforehand. Both the anesthesiologist and gastroenterologist expressed some skepticism regarding my fasting claim. I'm reaching out in search of any recommendations or insights. This ongoing illness has reached a point of frustration for me, and I desperately want to uncover its cause. The gastroenterologist who performed the endoscopy mentioned a possible gut-brain disorder, but this diagnosis is still quite vague. I am preparing for my next consultation and would appreciate any feedback. We have suspect cyclic vomiting syndrome for a while, but now I’m starting to wonder about gastroparesis as well. Honestly, I feel like this situation may have turned me into somewhat of a hypochondriac.

Understanding a Nodular Finding on My Appendix: Seeking Clarity

I'm a 22-year-old female, standing 4'9", with a background of EDS and anxiety. Recently, on January 30, 2026, I visited the emergency department due to kidney discomfort, which turned out to be a kidney stone. While reviewing my CT scan report to recall the size and location of the stone—still lodged and proving quite troublesome—I stumbled upon a mention of a nodular area on my appendix. This detail was not brought up by my doctor during my visit. Although I suspect it may not signal a serious issue, I'm curious if this is something I should discuss further with my primary care physician. Can anyone clarify what a nodular finding on the appendix means? I came across some information suggesting it could indicate a tumor, but I’m aware that online medical searches can often lead to misunderstandings. Any insights would be appreciated!

Dealing with Esophageal Cramping and Heartburn while on Oral Minoxidil

Hello everyone. I’m a 37-year-old male who frequently experiences alopecia areata, particularly during stressful periods at work. Recently, my dermatologist recommended oral minoxidil in 2.5mg capsules to speed up my hair restoration process. Since I began this treatment, I’ve encountered several side effects, including elevated heart rate, dizziness, shortness of breath, heartburn, and esophageal cramps, albeit not all at once. Most of these issues have subsided, but the cramps and intermittent heartburn persist. I find the cramps tend to occur after meals, accompanied by a sensation as if I can feel the food moving through my esophagus; this uncomfortable feeling can linger for hours before fading, only to return with my next meal. The discomfort isn’t severe enough to incapacitate me, but it can be quite bothersome, with some days being better than others. Should I consider halting the medication, or should I wait until my next scheduled appointment to discuss this? I live in a rural area, making it difficult to find sooner availability, as the next appointment isn’t for another month. I appreciate any advice you might have!
