Transmission-based Precautions I: Contact, Enteric, and Droplets01:17

Transmission-based Precautions I: Contact, Enteric, and Droplets

4.3K
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Transmission-based Precautions II: Airborne and Protective Environment

1.7K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Infection01:20

Infection

10.0K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Pulmonary Tuberculosis I

502
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Sexually Transmitted Infections01:26

Sexually Transmitted Infections

582
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Transcytosis of IgG01:15

Transcytosis of IgG

3.7K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Summary

This study found no evidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission via breast milk in Indian COVID-19 positive mothers. Neonatal testing also showed no signs of infection, suggesting breastfeeding is likely safe.

Area of Science:

  • Virology
  • Public Health
  • Neonatal Care

Background:

  • Concerns exist regarding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mother-to-child transmission during the COVID-19 pandemic.
  • The role of breastfeeding in potential SARS-CoV-2 transmission requires investigation, particularly in diverse global contexts.

Purpose of the Study:

  • To assess the possibility of SARS-CoV-2 transmission through breast milk in India.
  • To evaluate SARS-CoV-2 presence in breast milk and neonates of COVID-19 positive mothers.

Main Methods:

  • Descriptive study involving 30 COVID-19 positive mothers in India.
  • RT-qPCR analysis of breast milk samples for SARS-CoV-2.
  • RT-PCR testing of neonatal oropharyngeal swabs at 48 hours and day 5 of life.

Main Results:

  • One breast milk sample initially tested positive for SARS-CoV-2, but repeat testing the next day was negative.
  • All other breast milk samples from the 30 mothers were negative for SARS-CoV-2.
  • All paired neonatal oropharyngeal swabs tested negative for SARS-CoV-2.

Conclusions:

  • The study did not find conclusive evidence of SARS-CoV-2 transmission from mother to child through breast milk in the studied Indian population.
  • Breastfeeding may be a safe route of infant feeding for mothers with COVID-19, but further research is warranted.
