IIT DEVELOPS ULTRASOUND
FOR COVID-19 SCREENING
IIT- Palakkad has
developed an automated lung ultrasound (LUS) for COVID-19 screening and
monitoring through cloud –based image analysis and scoring system
The app, the first of
its kind in India, is now available for clinicians to perform automated
analysis by just uploading the ultrasound video
The institute has
developed the app in collaboration with clinical partners at La Paz Hospital,
Madrid, Spain (Dr. Yale Tung Chen), Sree Chitra Institute of Medical Sciences
and Technology (Dr. C. Kesavadas) and Government Medical College, Kottayam (Dr.
Kiran Vishnu Narayan)
IIT team conducted LUS
analysis of normal, viral, and bacterial infected lungs, using image processing
and neural networks and developed an automated LUS analysis tool
Approach is not
only restricted to COVID -19 detection but also helps to identify other lung
infections
World Health Organization declared the
outbreak a Public Health
Emergency of International Concern on 30 January 2020, and a
pandemic on 11 March
Spreads primarily when people are in close contact
and one person inhales small droplets produced by an infected person
(symptomatic or not) coughing, sneezing, talking, or singing. WHO recommends 1
metre (3 ft) of social distance
Sputum and saliva carry large amounts of virus. COVID‑19 is a new
disease, and many of the details of its spread are still under investigation
The usual incubation
period (the time between infection and symptom onset) ranges from
one to 14 days, and is most commonly five days
Symptoms: Fever, cough, fatigue,
shortness of breath, and loss of sense
of smell. Complications may include pneumonia
and acute respiratory distress syndrome
Some infected people have no symptoms, known as asymptomatic or presymptomatic carriers;
transmission from such a carrier is considered possible
Diagnosed on the basis of symptoms and confirmed
using reverse transcription
polymerase chain reaction (RT-PCR) testing
of infected secretions or CT imaging of the chest
Prevention: hand washing,
covering one's mouth when coughing, maintaining
distance from other people, wearing a face mask in public
settings, and monitoring and self-isolation
for people who suspect they are infected. Strategies in the control of an
outbreak are screening, containment (or suppression) and mitigation
Contact
tracing is an important method for health authorities to determine
the source of infection and to prevent further transmission
The outbreak is a major destabilising threat to the
global economy.
