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!

Seeking Insights: My Journey with Undiagnosed Neurological Symptoms
Hello everyone, I'm a 34-year-old female grappling with neurological symptoms that first appeared in October, and I’m eager to hear from anyone who might have faced similar challenges. My journey began with unexpected migraines, blurred vision, and an ongoing sensation of being off-balance or intoxicated. Gradually, I began experiencing mainly sensory-related symptoms, such as tingling and burning sensations, feelings of extreme heat and cold, sharp pains radiating in my arms and back, as well as discomfort in my hands and toes, alongside intermittent numbness. I also endure varying degrees of weakness and heaviness in my right side, specifically my arm and leg, although I haven’t suffered complete functional loss. The nature of my symptoms is erratic; they fluctuate rather than consistently deteriorate. An MRI revealed mild, scattered lesions in the white matter, which were deemed nonspecific. Further tests from a lumbar puncture returned normal results, showing no markers of inflammation, and the oligoclonal bands were not present. A thorough range of lab tests yielded no significant findings. After evaluating my case, the neurology team suggested a possible diagnosis of MS and administered a three-day course of intravenous steroids. While I noticed a slight improvement in some sensory pain, my symptoms persist and continue to vary day by day. I still experience headaches and pressure in my head along with episodes of blurred vision, but there have been no new deficits since treatment. I am reaching out to connect with others who have had similar experiences. I would like to learn about the insights or diagnoses you encountered and what treatments proved beneficial (such as those related to migraine disorders, dysautonomia, or sensory neuropathy, for example). If you have navigated a similar path, I would greatly appreciate your sharing your story. Thank you!
Should I Seek Medical Attention for Left Ear Pulsatile Tinnitus?
A 31-year-old woman reports an ongoing issue with pulsatile tinnitus, which she is currently experiencing solely in her left ear. Although she's noticed this condition intermittently before, she hadn’t paid it much mind due to the absence of pain. Recently, however, her curiosity piqued her interest in researching the condition, where she stumbled upon information suggesting it could be serious. Usually, she avoids searching online for health worries, but now she is contemplating whether a visit to the doctor might be warranted. Can anyone advise on the need for a medical evaluation in this case?
Concerns About Angular Cheilitis
I’m a 23-year-old woman with no history of smoking, and I’m seeking assistance regarding a health issue. Back in January, I experienced angular cheilitis three times, each episode involving a minor crack at the corner of my mouth that healed within a few days. Following the last occurrence, I became quite anxious due to saliva accumulation in that area. I found myself frequently brushing my finger along that spot. After a few days, I observed a small area forming that appeared white and had a rough texture. Eventually, I realized it was not just a coincidence, and I started taking action, but only after it became noticeably larger. To address it, I cleaned the area with a mix of alcohol and apple cider vinegar. I’m uncertain about what this issue could be, but I’ve recently begun using over-the-counter Clotrimazole cream while also keeping the area moisturized with either lanolin or petroleum jelly. Unfortunately, I haven’t noticed any improvement, and I’m concerned as it seems to be expanding. The patch continues to be rough and excessively dry. Although I can open my mouth wide without any cracks forming, I do feel tension in the skin, similar to having a bandage over that location. At times, I experience a burning sensation after thorough washing, and I’ve noticed tiny red spots appearing on the outer edges of the patch sporadically.
Unusual Heart Sensation
I’m an 18-year-old, weighing 50 kilograms and standing at 170 centimeters (and yes, I’m aware that I’m quite slender). For the past couple of years, I’ve developed a habit of smoking about half a pack of cigarettes each day. So, the other day I was lying on my left side, relaxing, when I stumbled upon an unusual sensation. It felt as though my heart was pulsating so intensely that it was almost outside my body. Out of curiosity, I pressed a bit on the area and was instantly hit with a rush; my head started to tingle, my vision momentarily blurred, and it felt as though my heart dropped. It was as if my entire system had malfunctioned. Just for context, I’ve experienced something similar before after a ketamine overdose, and it persisted for about a month afterward, occurring occasionally while trying to sleep or during random moments in bed. This current episode has me quite anxious, especially since it hasn’t happened in a while, but this time felt particularly alarming.
