There is no "typical presentation" of herpes. Some people after exposure will develop outbreaks or recurrences with a vesicular, painful rash. Others never see lesions or rashes. Even others - fall somewhere in between with localized pain coming first, followed by a rash. According to a recent study, some people with genital herpes may find that they have serious neuropathic pain (pain that follows nerve pathways) even if a rash or lesions never appear .
This study looked at 17 patients who complained of generalized chronic pain and had no signs of lesions. The majority of these patients were known to have herpes simplex virus. The researchers came to the conclusion that when some people get infected with the herpes virus, it may actually alter the pain processing mechanism in the central nervous system. Once these patients in the study were given anti-herpetic medication (like Acyclovir), the pain lessened considerably. So ...

Similarly, antibiotics and other drugs are used to protect livestock from diseases and parasites. Extra hormones may be given to animals to increase meat and milk production. In the U. S., use of these drugs is regulated by the FDA.
By getting rid of disease sources, pesticides and antibiotics help increase food production, reduce food loss, and keep the U.S. food supply safe from threats.
