Question: What are the transmission routes of Covid-19 and TB?

Answer passage (source: WHO):
page_title: Q&A: Tuberculosis and COVID-19
section_headers: Can tuberculosis and COVID-19 be tested on the same type of specimen?
section_content: The diagnostic methods for tuberculosis (TB) and COVID-19 are quite distinct
and commonly require different specimens.  
Sputum, as well as many other biological specimens, can be used to diagnose TB
using culture or molecular techniques.  
Tests for COVID-19 are done most commonly by nasopharyngeal or oropharyngeal
swab or wash in ambulatory patients, but sputum or endotracheal aspirate or
bronchoalveolar lavage may be used in patients with severe respiratory
disease. Molecular testing is the currently recommended method for the
identification of infectious COVID-19 and just as for TB, serological assays
are not recommended for the routine diagnosis of COVID-19.
The pipeline for COVID-19 diagnostics has flourished impressively within a few
months. Amongst these is the Xpert® Xpress SARS-CoV-2 cartridge for use on
GeneXpert machines, which are machines used in TB diagnosis. WHO is currently
evaluating this cartridge as well as other tests. Additional resources to roll
out COVID-19 testing should be mobilized rather than relying only on existing
resources that are used for TB, to ensure that the diagnostic coverage for TB
is maintained as necessary.

Reviewer feedback on this answer:
This answer does not address the question at all. The question asks about transmission, while the answer only describes testing/diagnostic methods.
This does not discuss the transmission routes for TB and COVID-19.

Answer passage (source: WHO):
page_title: Q&A: Tuberculosis and COVID-19
section_headers: What services can be leveraged across both diseases?
section_content: The response to COVID-19 can benefit from the capacity building efforts
developed for tuberculosis (TB) over many years of investment by national
authorities and donors. These include infection prevention and control,
contact tracing, household and community-based care, and surveillance and
monitoring systems.  
Although modes of transmission of the two diseases are slightly different,
administrative, environmental and personal protection measures apply to both
(e.g. basic infection prevention and control, cough etiquette, patient
triage).  
TB laboratory networks have been established in countries with the support of
WHO and international partners. These networks as well as specimen
transportation mechanisms could also be used for COVID-19 diagnosis and
surveillance.  
Respiratory physicians, pulmonology staff of all grades, TB specialists and
health workers at the primary health care level may be points of reference for
patients with pulmonary complications of COVID-19. They should familiarize
themselves with the most current WHO recommendations for the supportive
treatment and containment of COVID-19.  
TB programme staff with their experience and capacity, including in active
case finding and contact tracing, are well placed to support the COVID-19
response.
Various digital technologies used in TB programmes can support the COVID-19
response, including adherence support, electronic medical records and
eLearning.

Reviewer feedback on this answer:
This does not answer the question either. Although it's mentioned that modes of transmission for COVID-19 and TB are "slightly different", the actual transmission routes are not described.
This only touches on the transmission routes of TB and COVID-19, and does not thoroughly answer the question.

Answer passage (source: WHO):
page_title: Q&A: Tuberculosis and COVID-19
section_headers: Do COVID-19 and tuberculosis spread in the same way?
section_content: While both tuberculosis (TB) and COVID-19 spread by close contact between
people the exact mode of transmission differs, explaining some differences in
infection control measures to mitigate the two conditions.  
TB bacilli remain suspended in the air in droplet nuclei for several hours
after a TB patient coughs, sneezes, shouts, or sings, and people who inhale
them can get infected. The size of these droplet nuclei is a key factor
determining their infectiousness. Their concentration decreases with
ventilation and exposure to direct sunlight.  
COVID-19 transmission has primarily been attributed to the direct breathing of
droplets expelled by someone with COVID-19 (people may be infectious before
clinical features become apparent). Droplets produced by coughing, sneezing,
exhaling and speaking may land on objects and surfaces, and contacts can get
infected with COVID-19 by touching them and then touching their eyes, nose or
mouth . Handwashing, in addition to respiratory precautions, are thus
important in the control of COVID-19.

Reviewer feedback on this answer:
Provides a thorough explanation of TB transmission and COVID-19 transmission, and even explains how they differ and why this means safety precautions also differ.
This is a thorough and helpful answer that addresses the question directly.
