Understanding Contagion in Hand, Foot, and Mouth Disease
I understand that Hand, Foot, and Mouth Disease (HFMD) is at its most infectious right from the onset of initial symptoms, continuing to be highly transmissible until all sores have healed. However, I'm curious about whether an individual can spread HFMD before any noticeable symptoms arise. Any insights on this would be appreciated!

Hand, Foot, and Mouth Disease (HFMD) is a contagious viral infection primarily affecting young children, though it can also occur in adults. You're correct that it is most infectious during the initial symptoms and while active sores are present.
To address your question, yes, individuals infected with HFMD can spread the virus even before noticeable symptoms appear. This period of asymptomatic viral shedding, where the virus is present in the body but not yet causing visible signs of illness, can last for several days before the symptoms manifest. This is why HFMD can spread quickly in group settings, such as schools or daycare centers.
Key Points:
- Contagion Timeline: HFMD can be contagious 1-2 days before symptoms show and remains so until sores have healed.
- Viral Shedding: The virus can be present in respiratory secretions, saliva, and stool, contributing to its spread even before symptoms arise.
Next Steps:
- Hygiene Practices: Ensure thorough handwashing with soap and water, especially after using the bathroom and before eating.
- Avoid Close Contact: If someone is suspected to have HFMD, minimize close contact with others to reduce the risk of transmission.
- Disinfect Surfaces: Regularly clean and disinfect commonly touched surfaces, like toys and doorknobs, to limit the spread of the virus.
- Monitor Symptoms: If exposed to someone with HFMD, watch for symptoms such as fever, sore throat, or rash on hands, feet, and mouth for at least a week.
By taking these steps, you can help reduce the risk of spreading HFMD, even during the contagious period before symptoms develop. If you have further concerns or need additional information about prevention, feel free to ask!

The Risks of Swallowing Isopropyl Alcohol
As a 17-year-old considering a tongue piercing, I've been using isopropyl alcohol to disinfect my piercings. I am aware that ingesting this substance is highly discouraged, but I’m concerned about the possibility of inadvertently swallowing a small amount while cleaning my tongue. Would this pose any health risks? Could it lead to illness or adverse effects? I want to ensure I handle this correctly. If ingesting it is indeed harmful, I would opt for using salt water as an alternative for cleaning, although I'm aware that salt tends to upset my stomach, which complicates things.
Understanding Beta Hemolytic Streptococcus in Urine Culture and Its Symptoms
A 30-year-old female, weighing 148 lbs and not taking any medications, presents with escalating symptoms including a yellowish vaginal discharge, malodorous urine, and vaginal itching. A medical examination revealed significant inflammation both internally and externally around the cervix and vagina. Additionally, the patient reports persistent throat pain. This individual has faced ongoing symptoms, struggling to find a resolution. Despite undergoing several tests, results for yeast infections, bacterial vaginosis, and sexually transmitted diseases have all returned negative. However, upon further investigation and requests for different evaluations, a vaginal swab confirmed the presence of gram-positive cocci, and a urine culture identified the growth of beta hemolytic streptococcus at a level of 50,000-100,000 colony-forming units per milliliter. The patient inquires whether antibiotic treatment is necessary and if this bacterial infection might be related to her vaginal symptoms. She has experienced recurrent issues typically associated with bacterial vaginosis (BV). Various treatments have been trialed with limited success; metronidazole has not provided relief, while extended courses of clindamycin have only yielded temporary respite, lasting about a month at most. Additionally, the patient mentions that her partner is dealing with periodontal disease, prompting concerns about whether this condition may contribute to her recurring symptoms. She also notes that her throat remains sore and red, accompanied by nearly complete swelling in her sinuses, raising the question of a potential connection between these symptoms and the identified infections.
Concerns About Incomplete Breast Examinations at the Gynecologist
Hello, I'm a 24-year-old female, standing at 4'11" and weighing 90 pounds; I have no medical conditions and no significant family health history. During my visits to the gynecologist, I typically wear my gown with the opening in front. I try to keep it closed, but when she checks my heart, the gown gets opened, revealing my breasts. Is this standard practice? After checking my heart, she shifts the gown underneath my breast to examine it, and she continues to leave the gown open while also examining my abdomen. In contrast, my regular doctor instructs me to wear the gown with the opening at the back and doesn’t pull it up to check my heart. I often feel uncomfortable and overly exposed during my gynecological appointments when I believe it could be handled differently.
Concerns About My Son's Recent Diagnosis of Mastoiditis
Today, I took my 13-year-old son to the physician to investigate an unusual hard lump located behind his ear. This bump has been present for approximately one to two months, though I only became aware of it a month ago. After examining it, the doctor diagnosed him with Mastoiditis and appeared to downplay its significance. Notably, my son shows no signs of fever and reports no discomfort. The doctor also examined his ears and confirmed that everything seemed normal before sending us home. Feeling a bit uneasy, I later researched Mastoiditis online and discovered that it can be a serious condition. Now, I'm left wondering if I should seek a second opinion from another healthcare provider, as I am quite concerned. My son appears to be in good health and is not taking any medications, standing at 5 feet 9 inches tall and weighing 125 pounds. I appreciate any advice from medical professionals!
Concerns About Potential Medical Malpractice
A few days ago, my 23-year-old partner underwent surgery for an appendix removal. Initially, the procedure was intended to be laparoscopic; however, complications arose when their appendix ruptured, leading to an infection. Consequently, the surgical team had to perform a larger incision and close it using staples. Presently, my partner is on a 3mg regimen of morphine to manage pain, and they have a Jackson-Pratt (JP) drain in place, which has recently stopped producing significant fluid. This decline raised the doctor's concerns regarding possible pus accumulation in my partner's abdomen. During a follow-up examination, the doctor did not inform us about the intended procedure. He abruptly pulled back the covering and began to apply pressure at the stitch site. Some drainage emerged, prompting discomfort for my partner. Without any prior warning, the doctor requested a staple remover from a nurse. When the nurse could not locate one immediately, the doctor left the room, displaying impatience. I suggested to my partner that they might want to ask for additional pain relief before the doctor returned. My partner indicated they would relay their pain level to the doctor during the procedure. Upon the doctor’s return, he still failed to explain the impending actions. He proceeded to remove several staples, forcefully inserting the staple remover into the incision. This action reopened the wound, causing my partner to react in visible pain. As the doctor continued to manipulate the staple remover awkwardly within the incision, he offered sporadic apologies, seemingly indifferent to my partner's distress. Notably, there was no nursing staff available during this time, although one nurse walked by and appeared alarmed at the doctor’s conduct. The doctor continued to squeeze around the incision to expel any remaining fluid while intermittently grabbing gauze to dab the area before forcefully re-engaging the staple remover. Remarkably, at no point did the physician inquire about my partner's pain level or the last administration of pain medication, which had been some time prior. Eventually, he used gauze to absorb the fluids, covering the wound with fresh tape, ultimately leaving it open for further drainage. I recognize that some medical scenarios necessitate reopening a wound, but the manner in which it was executed raised numerous red flags. The lack of prior communication, failure to assess pain levels, absence of nursing support, and the aggressive technique used to reopen the incision all contribute to my concerns. Following this ordeal, my partner appeared emotionally drained, visibly pale, and lost in thought, as if they had given up hope. When a nurse returned, my partner could barely articulate their need for another dose of pain medication, which was administered. Upon reflection, they stated they would have requested pain relief had they been forewarned of the doctor's actions. Even when I offered to ask a nurse to clarify what the doctor intended, my partner resignedly replied that it would be futile, as even the nurses seemed unaware. While I understand that post-surgical recovery can be painful, it seems excessive discomfort could have been minimized with straightforward communication about the forthcoming procedures. Currently, my partner is sleeping deeply, their skin feeling unusually cool to the touch, which has left me concerned. It's been increasingly difficult to maintain their spirits after the distressing experience they endured. In summary, is the doctor's conduct—specifically using a staple remover without warning, failing to check on my partner's pain level, and conducting the procedure without a nurse present—indicative of medical malpractice?
