Leading dentist in Chennai | HSV Infections in Babies: What Parents Need to Know Herpes Simplex Virus (HSV) can pose serious risks to babies due to their undeveloped immune systems. It may cause oral sores, fever, irritability, and, in severe cases, life-threatening complications. Transmission often occurs through direct contact, such as kissing, by someone with an active HSV infection. Preventative measures include avoiding contact with cold sores and maintaining strict hygiene. Early diagnosis and treatment are crucial. At Dr. Akkshaya Dental & Aesthetics, we emphasize awareness and care for your baby’s oral health.
