This phase is characterized by decreased CD4+ cell counts, viral entry, where the virus infects epithelial cells, produces prog- loss of immune responses, and onset of opportunistic infections eny viruses, and eventually causes cell death. In response to various stimuli, such as intense sunlight, emotional The virus is most commonly spread by sexual intercourse, injec- stress, febrile illness, or menstruation, this latent virus may become tion of intravenous drugs with contaminated needles, mucous reactivated and lead to viral reproduction and shedding. Although the virus is found in most and neonatal herpes is a serious complication of maternal genital her- body ﬂuids, infection has primarily been associated with exposure pes. Neonatal herpes usually becomes evident within the ﬁrst week to blood, semen, or vaginal secretions. The virus is not spread of life and may be manifested by the typical clusters of blister- through casual contact. Health care workers have been infected by like lesions on skin or mucous membranes. Irritability, lethargy, needlestick injuries and should be aware that postexposure pro- jaundice, altered blood clotting, respiratory distress, seizures, or phylaxis is available and may signiﬁcantly reduce the risk of trans- coma may also occur. In immunosuppressed patients, HSV infection may result in The respiratory syncytial virus (RSV) is a highly contagious virus severe, systemic disease.

In older children, RSV infection produces much milder disease but RSV is the most common cause of bronchiolitis and pneumonia may be associated with acute exacerbations of asthma. These infants usually have wheezing, cough, respiratory symptoms of fever, cough, and nasal congestion. The infection is usually self-limited and re- most often in those with household or other close contact with chil- solves in 1 to 2 weeks. Antiviral therapy with ribavirin is used in dren, including pediatric health care workers. The mortality rate from RSV infection is low in chil- RSV infection may cause pneumonia requiring hospitalization. In dren who are generally healthy but increases substantially in those immunocompromised patients, RSV infection may cause severe with congenital heart disease or immunosuppression. Once inside host cells, viruses use cellular metabolic ac- pends on cell-mediated immunity (lymphocytes and tivities for their own survival and replication. Viral repli- macrophages) to eradicate the virus along with the cation involves dissolution of the protein coating and cell harboring it. Viral infection may occur without signs and symp- [DNA] or ribonucleic acid [RNA]). Then, host cell genes are coded to produce new viruses (eg, herpesviruses) can survive in host cells viruses. Also, autoimmune ing host cell mitosis and becomes part of the inherited diseases may be caused by viral alteration of host cells genetic information of the host cell and its progeny. Symptoms usually associated with acute viral infec- tase before replication can occur. When the cell is destroyed, the signs and symptoms vary with the type of virus and viruses are released into the blood and surrounding tis- body organs involved. Antibodies are Antiviral Drugs proteins that defend against microbial or viral invasion. They are very speciﬁc (ie, an antibody protects only Few antiviral drugs were available before the AIDS epi- against a speciﬁc virus or other antigen). Since then, numerous drugs have been developed to a person who has had measles, antibody protection (im- treat HIV infection and opportunistic viral infections that munity) develops against future infection by the measles occur in hosts whose immune systems are suppressed by virus, but immunity does not develop against other viral AIDS or immunosuppressant drugs given to organ transplant infections, such as chickenpox or hepatitis. Drug therapy for viral infections is still limited, The protein coat of the virus allows the immune sys- however, because drug development is difﬁcult. Viruses use tem of the host to recognize the virus as a foreign the metabolic and reproductive mechanisms of host cells for invader and to produce antibodies against it.
