Zika virus (ZIKV) is an emerging mosquito-borne pathogen belonging to the genus of the family . is widely distributed in China. However, little is known about the vector competence of in China. The present study presents the oral susceptibility and vector competence of Guangzhou strain to ZIKV. Additionally, vertical transmission of ZIKV is described. The results demonstrated the susceptibility of local mosquitoes to ZIKV with an extrinsic incubation period of 6 days. Disseminated infection was observed in starting on day 2 postinfection (PI). Starting on day 6 PI, the saliva of exhibited ZIKV infection, and the transmission rate was 36.4%. Vertical transmission was observed during the first gonotrophic cycle. The minimum infection rate was observed in third-to-fourth instar larvae.

We characterized natural vertical transmission of Zika virus in pools of Aedes aegypti larvae hatched from eggs collected in Jojutla, Morelos, Mexico. Of the 151 pools analyzed, 17 tested positive for...
In a recent outbreak of Zika virus (ZIKV) infection in Jaipur city (Rajasthan, India), a total of 159 cases were reported in September 2018. In order to identify vector responsible for Zika transmissi...

Zika virus (ZIKV) has emerged as a globally important arbovirus and has been reported from all states of Brazil. The virus is primarily transmitted to humans through the bite of an infective Aedes aeg...
Detecting and monitoring the transmission of arboviruses such as Zika virus (ZIKV), dengue virus, and chikungunya virus is critical for prevention and control activities. Previous work has compared th...
Dengue viruses are the most medically important arthropod-borne pathogens worldwide, with transmission occurring in most tropical and sub-tropical regions. An estimated 390 million infecti...
In this prospective observational study the investigators will report on 20 male subjects with proven WHO-classification Zika infection. These subjects will be followed up for a maximum of...
The purpose of this study is to determine whether any diagnostic patterns exist in the symptom presentation of Zika Virus.
Currently, there are no licensed therapeutics against Zika virus infection. Due to this unmet medical need, Zika Virus Immune Globulin (ZIKV-IG) is being developed as a therapeutic interve...
The clinical trial will assess the safety, tolerability, and immunogenicity of GLS-5700. GLS-5700 is a synthetic DNA plasmid vaccine against the Zika virus. ZIKA-001 is the first in man cl...
The expelling of virus particles from the body. Important routes include the respiratory tract, genital tract, and intestinal tract. Virus shedding is an important means of vertical transmission (INFECTIOUS DISEASE TRANSMISSION, VERTICAL).
An order of the class Insecta. Wings, when present, number two and distinguish Diptera from other so-called flies, while the halteres, or reduced hindwings, separate Diptera from other insects with one pair of wings. The order includes the families Calliphoridae, Oestridae, Phoridae, Sarcophagidae, Scatophagidae, Sciaridae, SIMULIIDAE, Tabanidae, Therevidae, Trypetidae, CERATOPOGONIDAE; CHIRONOMIDAE; CULICIDAE; DROSOPHILIDAE; GLOSSINIDAE; MUSCIDAE; TEPHRITIDAE; and PSYCHODIDAE. The larval form of Diptera species are called maggots (see LARVA).
An arbovirus in the FLAVIVIRUS genus of the family FLAVIVIRIDAE. Originally isolated in the Zika Forest of UGANDA it has been introduced to Asia and the Americas.
A viral disease transmitted by the bite of AEDES mosquitoes infected with ZIKA VIRUS. Its mild DENGUE-like symptoms include fever, rash, headaches and ARTHRALGIA. The viral infection during pregnancy, however, may be associated with other neurological and autoimmune complications (e.g., GUILLAIN-BARRE SYNDROME; and MICROCEPHALY).
The transmission of infectious disease or pathogens. When transmission is within the same species, the mode can be horizontal or vertical (INFECTIOUS DISEASE TRANSMISSION, VERTICAL).
