What are the symptoms of Zika virus?

The main transmission route of Zika virus is through mosquitoes, but in very rare cases it is transmitted through sexual intercourse, so everyone must pay attention to it. There is currently no treatment for Zika virus, so when you go to an unfamiliar environment, you must take certain anti-mosquito measures and pay attention to your own hygiene to avoid the invasion of the virus.

Virus Introduction

Zika virus Zika virus, also known as Zika virus, is a mosquito-borne virus that is mainly spreading in various regions of Brazil.

In February 2018, the WHO released its annual list of pathogens, listing ten deadly viruses that pose an "urgent" threat to human health and require close monitoring. The Zika virus is among them.

Main symptoms

The Public Health Agency of England said that the Zika virus that causes Zika fever does not appear naturally in the UK, but the virus can be transmitted by mosquitoes. In rare cases, the virus can also be transmitted through sex or from mother to child. Babies born to pregnant women infected with the Zika virus may be born with microcephaly. Symptoms of Zika fever include fever, rash, joint pain, muscle pain, and non-purulent conjunctivitis.

What are the symptoms of Zika virus?

Zika virus (ZIKV) belongs to the Flaviviridae family, Flavivirus genus, and can be transmitted to humans by Aedes mosquitoes. Like other viruses in the Flaviviridae family, Zika virus has an envelope and an icosahedral protein capsid and is a positive-strand RNA virus. The virus most closely related to it is the Spondweni virus. In humans, it causes a mild illness called Zika. Zika disease, or Zika fever as it is also known, has been confined to a narrow strip of Africa and Asia near the equator since the 1950s.

Zika virus can be transmitted by mosquitoes that are active during the day. Several species of Aedes mosquitoes are known to transmit the virus. Studies have shown that the external incubation period of Zika virus in the Aedes mosquito is about 10 days. The vertebrate hosts of the virus are mainly monkeys and humans. At present, the pathogenesis of the virus is still unclear. The scientists hypothesize that the Zika virus initially infects the juxtanuclear region of dendritic cells and then spreads to the lymph nodes and blood. Flaviviridae viruses typically replicate in the cytoplasm, but Zika virus antigens have been found in the nucleus of infected cells.

The virus causes symptoms that are like a mild form of dengue fever. Common symptoms of infection with the virus include mild headache, maculopapular rash, fever, malaise, pink eyes and joint pain. It starts with a mild headache and progresses to a maculopapular rash, fever, and back pain. Within two days, the rash subsided, and within three days, the fever was over, but the rash remained. There is still no effective vaccine or treatment.
