HSVs can be reactivated by illnesses such as colds and influenza, eczema, emotional and physical stress, gastric upset, fatigue or injury, by menstruation and possibly exposure to bright sunlight. HSVs establish lifelong infection and it cannot be eradicated from the body. However Antivirals like Acyclovir can be used to reduce the severity and reduce the recurrence rates. In addition to antivirals, You need to follow some Keep the genitals and blisters clean and dry Wear loose and cotton clothes Wash hands regularly.Keeping your immune system at its full capacity is important for maintaining an outbreak-free lifestyle with herpes.
