Which of the following ways can cause the virus to be transmitted to an infant?

At present, the viral infectious diseases that can cause mother-to-child transmission are AIDS, syphilis, hepatitis B, hepatitis C, etc. Of course, even if the mother or father has the above diseases or is a carrier of the virus, medical intervention during pregnancy and pregnancy can give birth to a healthy baby. Wish.

Hand-to-hand contact, spraying in front of a baby, mouth-to-mouth feeding, etc., can spread the virus.

Direct contact with people with the virus, direct use of utensils from people with the virus, and feeding babies to people with the virus.

Mother-to-child transmission is one of the leading sources of infection, and when a mother is infected, the child is infected by breastfeeding. The second is contact with items with infectious agents.

Answer]: c The transmission of AIDS includes sexual and violent contact transmission, injection transmission, mother-to-child transmission, and contamination of medical staff by contaminated needle and damage**. A, B, and E are mainly transmitted by teasing socks and passing through a fecal route.

d The mode of transmission is human contact with plague-infected animals, vector insects, plague patients and their carcasses, bacterial secretions, etc.

Answer] :d mother-to-child transmission refers to transmission from mother to fetus or infant, and mother-to-child transmission is vertical transmission. Diseases that can be transmitted from mother to child include:

Viral hepatitis B, viral hepatitis C, viral hepatitis D, epidemic blood fever, AIDS, etc.

Correct answer: c

Analysis: Transmission of typhoid fever: through the fecal-oral route.

Transmission of cholera: through the fecal-oral route.

Transmission of AIDS: 1 Sexual transmission; 2 Transmission of blood or blood products; 3 Mother-to-child transmission.

Transmission route of plague: insect vector transmission, mostly to"Fleas"Disseminate.

Transmission of bacillary dysentery: mainly through the fecal-oral route. Therefore, C

Answer B Test point: Common viral infectious diseases (including AIDS) Analysis: Infectious diseases refer to diseases caused by pathogens, which can be transmitted between people and between humans and animals, with the characteristics of infectiousness and epidemic, and pathogens are the general name of microorganisms and parasites that can cause infectious diseases of humans and animals and plants Among them, there are bacteria, viruses, fungi (such as molds that cause jaundice), protozoa (such as malaria parasites), helminths (such as roundworms) and mites (such as scabies mites).

Answer: Solution: a. The causative agent of schistosomiasis is schistosomiasis, which is a parasite and does not meet the meaning of the topic b. AIDS, the abbreviation of acquired immunodeficiency syndrome, is a syndrome in which human beings are immunodeficient due to infection with human immunodeficiency virus (HIV), and a series of complications and tumors occur in the later stage, which can lead to death in severe cases

c. The causative agent of bacillary dysentery is dysentery bacillus, which belongs to bacteria and does not conform to the topic D. The pathogen of gonorrhea is gonorrhoeae diplococcus, which belongs to bacteria and does not conform to the topic Therefore, the key to this question is to clarify the characteristics of various diseases, especially the characteristics of AIDS

Babies are not as strong as adults, they are quite susceptible to illness and infection, try to take precautions, and know more about the things that babies need to pay attention to when they are sick, so that they will not be in a hurry.

Viral and bacterial double infection can be taken orally some anti-inflammatory drugs, anti-diarrheal drugs for **, if the medication is not obvious for 3 5 days, it is recommended to take the baby to the hospital for examination, and you can also inject some injections**, positive**, to prevent aggravation of the condition caused by dehydration.

It is a piece of deoxyribonucleic acid or ribonucleic acid encased in a protective shell. Through the mechanism of infection, these simple organisms can replicate themselves using the host's cellular system, but cannot grow and replicate independently. Viruses can infect almost all organisms that have cellular structures.

Viruses are made up of two or three components: viruses all contain genetic material (RNA or DNA, prions made up only of proteins are not viruses); All viruses also have capsids formed by proteins, which are used to encapsulate and protect the genetic material within; In addition, some viruses are able to form lipid envelopes when they reach the cell surface.

Viruses come in many forms, from simple helices and icosahedrals to complex structures. Virus particles are about one hundredth the size of bacteria. The ** of the virus is still unclear.

Different viruses may originate from different mechanisms. Some viruses may be plasmids (a type of cyclic DNA that can replicate within cells and be transferred from cell to cell), while others may be bacteria. From the classification of genetic material:

Deoxyribonucleic acid viruses, ribonucleic acid viruses, protein viruses (e.g., prions), from the classification of virus structure: euvirus (abbreviated as virus) and from the classification of host types:

Subviruses (subviruses, including viroids, pseudoviruses, prions) of bacteriophages (bacterial viruses), plant viruses (e.g., tobacco mosaic virus), animal viruses (e.g., avian influenza virus, smallpox virus, HIV virus, etc.). From natural to: mild viruses (e.g., HIV), virulent viruses (e.g., rabies virus).

If the baby is often infected with the virus, it is possible that the child's resistance is problematic, and the virus is transmitted through air contact, clothing, etc

Viruses are transmitted through the respiratory tract and droplets, such as rubella virus, influenza virus, etc. These viruses are relatively common, so it is important to protect your baby from infection. The virus can also spread through the digestive tract. If the virus contaminates food and water sources.

Therefore, giving your child the hepatitis A vaccine in advance can effectively improve your child's resistance to the hepatitis A virus. Hepatitis A vaccination generally does not cause serious reactions, and if there is local pain, redness and swelling, it usually resolves spontaneously within 72 hours.

Viral and bacterial double infection can be taken orally some anti-inflammatory drugs, anti-diarrheal drugs for **, if the medication is not obvious for 3 5 days, it is recommended to take the baby to the hospital for examination, and you can also inject some injections**, positive**, to prevent aggravation of the condition caused by dehydration.

It is possible that there is a problem with the child's resistance, and the virus is transmitted through air contact, clothing, etc
