Context:
According to the World Health Organization (WHO), pathogens that are transmitted through the air will be described by the term ‘ Infectious Respiratory Particles’ (IRPs).
More on the news:
- The World Health Organization (WHO) has released a report titled ‘Global technical consultation report on proposed terminology for pathogens that transmit through the air’.
- The WHO has introduced the term to address the lack of a common language during the COVID-19 pandemic and facilitate better communication.
- The varying terminologies used by experts highlighted gaps in common understanding and hindered efforts to curb pathogen transmission. The new term IRPs aims to provide clarity.
- The pathogens Include those that cause respiratory infections like COVID-19, influenza, measles, MERS, SARS, and Tuberculosis(TB), among others.
Respiratory Particles
- They are tiny airborne objects we breathe in, impacting our health.
- The particles that are generated contain, in addition to water, many other constituents, including salts, proteins, mucus, and pathogens such as bacteria or viruses.
Types:
- Droplets: Larger (over 5 micrometers) expelled through coughs, sneezes, etc.
- Aerosols: Smaller (under 5 micrometers) and linger in the air longer.
- Airborne dust: Includes dust mites, pollen, and mold spores.
- Size Matters: Larger droplets get trapped in the upper airways, while smaller aerosols reach the lungs.
- Health Risks: These particles can lead to respiratory illnesses like the common cold, flu, COVID-19, and asthma.
Global Technical Consultation Report:
- It aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities.
Impact and Importance:
- Consensus on terminology will guide research agendas and public health interventions.
- Enhances identification, communication, and response to existing and new pathogens.
