There are four serotypes:
Herpetic whitlow Vesiculation and ulceration appears on the infected area. Care should be taken not to incise the wound because the content of the vesicles are infectious and the condition is self-limiting causing minimal symptoms. Herpetic kerato-conjunctivitis Herpes simplex may affect the eyes causing corneal ulcerskeratitis or kerato-conjunctivitis.
The adjacent skin of the eyelids may show herpetic vesicles and ulceration. Herpes progenitalis This is a venereal disease, which is sexually transmitted. The condition begins with burning and tingling on the affected skin followed by the appearance of small vesicles that tend to ulcerate.
The course is short but recurrence is common at the same site or near by in the genital area. The common site is on the penis and scrotum in males, vulva and vagina in females.
Infected mothers may transmit the disease to their babies during or after labor. Anogenital herpes in infants and children Ano-genital herpes in younger age groups have number of possible causes.
Sexual abuse should be considered where thorough history and investigations are necessary to detect the mode of infection. Direct infection from the nursery, mother, housemaids or others may be one of the possible causes Central nervous system herpetic infection Rarely herpes virus may invade the nervous system leading to encephalitis, meningeal irritation, and cranial nerve lesions with localized neurological signs and coma.
The condition may be fatal. Recurrent herpes simplex One of the distinct features of herpes simplex is its tendency for recurrence. It is believed that the herpes virus becomes dormant in the tissues and flare up when there is optimum predisposing factors. Herpes simplex has certain familial tendencies and infection with the virus will not lead to lasting immunity as most other viruses.
Recurrence of the herpetic attack usually involves the same previous location or a near by areas. Recurrence of the lesion may be precipitated by different factors such as common cold, fever, strong sunlight, psychic trauma, gastrointestinal upset and menses.
Almost all humans eventually had an attack of herpes simplex during their life. Diagnosis of herpes simplex Diagnosis of herpes simplex can be established by: This is usually expensive and rarely needed.
Treatment It should be noted that topical corticosteroids are contraindicated in viral disease infection since they may cause flare up of the lesions and depress serum interferon. Mild uncomplicated eruptions of herpes simplex require no treatment. Mucocutaneous lesions may be treated simply by 10 percent aluminium acetate or 1: Topical Acyclovir is of established value for herpetic keratitis.
Treatment should be started as soon as possible. In neonatal herpes and encephalitis:EC Microbiology. EC Microbiology (ECMI) is a multidisciplinary and internationally peer-reviewed journal that covers significant advancements in the field of microbiology encompassing bacteria, viruses, archaea and all the other microbes.
Clinical Dengue. Infection with any of the four dengue serotypes can produce the full spectrum of illness and severity.
The spectrum of illness can range from a mild, non-specific febrile syndrome to classic dengue fever (DF), to the severe forms of the disease, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). Mosquito-borne diseases or mosquito-borne illnesses are diseases caused by bacteria, viruses or parasites transmitted by regardbouddhiste.com can transmit disease without being affected themselves.
Nearly million people get a mosquito-borne illness each year resulting in over one million deaths. Microbiology Gateway. Information, current research and relevant technology (including metagenomics, qPCR, real-time PCR, nanotechnology, genomic analysis, DNA sequencing and computational biology) on all aspects of microbiology .
El dengue es una enfermedad infecciosa causada por el virus del dengue, del género flavivirus que es transmitida por mosquitos, principalmente por el Aedes regardbouddhiste.comn 4 tipos del virus de dengue.
La infección causa síntomas gripales, y en ocasiones evoluciona hasta convertirse en un cuadro potencialmente mortal, llamado dengue grave o dengue . TEXT. Dengue virus (DV) infections are transmitted to humans by Aedes sp. mosquitoes and are the leading cause of arbovirus-associated disease and death in tropical and subtropical locales throughout the world (2, 6, 15).Symptoms associated with primary infection by any of the 4 DV serotypes include fever, headache, and muscle and joint pains (6, 15).
