How does Zika virus spread 1, mosquito transmission
Mosquitoes are the main spreaders of Zika virus. When mosquitoes bite Zika virus carriers, they will carry the virus in their bodies, and when they bite the next target, they will spread the virus to the target. Because of the huge mosquito population, it is hard to prevent, and it is easy to be infected by mosquitoes.
2. Body fluid transmission
Zika virus can also spread from person to person, because the virus can survive in the human body, so Zika virus can also spread through body fluids. Zika virus patients will spread the virus to each other through body fluids when they are in close contact with ordinary people, which will lead to infection.
3, mother-to-child transmission
If pregnant women are infected with this virus, or lactating mothers are infected with this virus, it will also be transmitted to fetuses and infants through umbilical cord and milk, leading to their infection. Infants and young children's immunity is very weak, there is almost no subjective protection measures, and they are vulnerable to great harm.
Zika virus prevention method
Zika virus prevention is very important because there is no effective treatment at present. The first thing to do to prevent Zika virus is to prevent mosquito bites. In the season when mosquitoes are prevalent, you must wear anti-mosquito clothing when you go out to avoid being bitten by mosquitoes. Screen windows and screen doors can be installed at home to prevent mosquitoes from entering. Installing mosquito nets in sleeping environment can further avoid being bitten by mosquitoes. In epidemic areas, avoiding contact with others, especially close contact, can effectively prevent infection with the virus.
Viral harm of Zika virus
After being infected by the virus, it is very harmful to health. The human body will be affected by virus infection, and its own tissues and organs will be destroyed, so it is prone to skin diseases, gastrointestinal diseases, vision loss and other adverse effects. Moreover, pregnant women and babies are the most affected by Zika virus. After being infected with the virus, it will seriously affect the growth and development of the body, leading to fetal hair malformation and microcephaly with a high probability, which will adversely affect the growth and development of infants and children, and there will be adverse reactions such as mental decline, brain dysfunction and cranial nerve disorder. Human body is infected by virus, and its immunity is reduced, so it is easy to be infected with other diseases. Once multiple diseases are complicated, it will be more harmful to health. Zika virus can cause autoimmune disorder and nervous system disorder. If the situation is serious, it is easy to have various complications, which will be life-threatening.
Treatment measures of Zika virus
Because there is no effective treatment at present, there are only some ways to enhance the autoimmune ability. Don't take aspirin during illness. Aspirin is basically ineffective and may cause adverse reactions. You can take some anti-inflammatory drugs to enhance your resistance to the virus. Some antipruritic and detumescence drugs can be applied to the affected area of the skin to improve the immunity of the skin. For patients with pain symptoms, some analgesic drugs can be taken, which can effectively relieve the pain.
Zika virus
Zika virus belongs to flaviviridae, flavivirus, single-stranded positive-stranded RNA virus, with a diameter of 20nm. It is an arbovirus spread by mosquitoes, and its host is unknown. It is mainly spread among wild primates and mosquitoes living in trees, such as Aedes africanus. The virus was first discovered accidentally in rhesus monkeys in Zika jungle of Uganda through yellow fever surveillance network in 1947, and then in Uganda and Tanzania in 1952. The virus activity has been relatively hidden, and there are only sporadic cases of Zika virus infection in Africa, America, Asia and the Pacific region around the equator. The first epidemic occurred in Yap Island, Cronia Islands in the western Pacific in 2007, and the largest epidemic occurred in French Polynesia in Oceania from 20 13 to 20 14, with about 32,000 infected people. Aedes mosquitoes also spread three other viruses in flaviviridae, including dengue virus, chikungunya virus and yellow fever virus, which are mainly prevalent in tropical and subtropical regions. Decades ago, African researchers noticed that Zika virus spread by Aedes mosquitoes inexplicably followed Chikungunya virus spread by Aedes mosquitoes. A similar pattern began at 20 13, chikungunya virus spread from west to east, followed by Zika virus.
