- Becoming infected with COVID-19 after touching a contaminated surface. (correct)
- Contracting malaria after being bitten by an infected mosquito.
- Acquiring rabies through the bite of an infected animal.

In the context of infectious disease transmission, which of the following distinguishes congenital infections from postnatal infections?
In the context of infectious disease transmission, which of the following distinguishes congenital infections from postnatal infections?
- Congenital infections manifest only after delivery, whereas postnatal infections are present in utero.
- Congenital infections are exclusively transmitted through breast milk, while postnatal infections occur via direct contact.
- Congenital infections are acquired in utero, while postnatal infections occur after birth. (correct)
- Congenital infections are caused by viral pathogens, and postnatal infections are caused by bacterial pathogens.

- A mother passing HIV to her child during pregnancy. (correct)
- A person becoming infected with salmonella after consuming contaminated food.

Study Notes
- There are two modes of infectious disease transmission to humans: general (non-human to human) and human to human.
Non-Human to Human Transmission Examples
- Soil: Transmission of Chicanas.
- Water: Transmission of avias.
- Food: Transmission of salmonellas.
- Animals/Animal Bites: Transmission of rabies.
- Formites: Transmission of COVID-19 and HPV.
- Insects/Insect Bites: Transmission of malaria and initial gasses.
Human to Human Transmission
- Can occur via direct contact, indirect contact, droplets, airborne transmission, or fecal-oral route.
- Direct Contact: Transmission of HIV, trapez virus, and Ebola virus.
- Indirect Contact: Transmission of influenza and norovirus.
- Droplets: Transmission of Alois and borders.
- Airborne: Transmission of influenza and tuberculosis.
- Fecal-Oral Route: Transmission of COVID, Coronavirus and sugar.
Medical Transmission
- Defined as the passage of a disease-causing agent from mother to baby before, during, or after delivery.
- Transmission can occur via the placenta, breast milk, or direct contact.
Congenital Infections
- Caused by pathogens while the baby is still in the uterus.
- Examples: Transmission of rubella, CMB, and HIV.
- COVID infection can be passed from mother to baby either in the uterus or during delivery.
- Examples: Transmission of nisibinovia, chemos and HSV.
Postnatal or Postpartum Infections
- Occur after delivery, usually beginning in the fixtures.
- Examples: Transmission of mycelia granule and HIV.
Pathogen Entry Points and Diseases
- The level of infectious agents entering the body matters, varying by pathogen.
Respiratory Tract
- Ex: Ptetrafocus Pneumonia enters through the respiratory tract, causing pneumonia.
Gastrointestinal Tract
- Ex: Shigella dysentery enters the gastrointestinal tract, causing dysentery.
Skin
- Ex: Prostate enters through the skin, causing tetanus.
- Tetanus and rabies also enter through the skin.
Genital Tract
- Ex: Lyceum enters Learning Objective video.
