DRDO develops N99 masks, ventilators and hand sanitizers to help fight against COVID-19

The DRDO (Defence Research Development Organization) has been tracking the spread of the COVID-19 virus since it began to spread in China. Now, the organization has developed four items to help India in its “War against Corona”.


The DRDO has developed hand sanitizer, ventilators, five-layer masks and body suits.

Hand Sanitizer

Around 4,000 litres of hand sanitizers have been developed for the Indian Armed Forces, Security Corps and Medical corps. The organization has developed 1,500 litres for the Ministry of Defence and 300 litres for the Parliament.

DRDO is to make 20,000 to 30,000 litres of hand sanitizers per day. The cost of the sanitizers is less than Rs 120 per litre

N99 masks

DRDO has developed 5-layer N99 masks. Among the five layers, 2 layers are made of nano mesh. The organization is to manufacture 10,000 such masks a day. The cost of the mask is Rs 70 per piece


The Society for Biomedical Technology programme, operating under DRDO has been modified to fulfil the current needs. The programme will now be deployed to manufacture ventilators. Around 5,000 ventilators are to be produced in the first month. It is then to gradually be increased to 10,000 in the subsequent month.

Body Suits

The body suits developed by DRDO earlier for medical and paramedical staffs for radiological emergencies has now been converted into a full body suit that will help to stop contamination.

Mutation and Pangolins main source of COVID-19

According to a research published in the journal “Pathogen”, virus jumped to humans from Pangolins. Also, mutation was the main reason for the virus to target human cells so easily and hence leads to fast spread of the virus.


The study has found that the virus has jumped to humans from Pangolins. Pangolins are the most trafficked animals in China. They are traded for their medicinal values. The initial cases of the virus were reported to have originated from the Hunan market of Wuhan city where illegal trade of Pangolins is common. Wuhan was the epicenter of the COVID-19 outbreak.

How does the Virus enter Human Cells?

The COVID-19 virus has a spike protein. These proteins contain Receptor Binding Domain (RBD) that facilitates the entry of the virus. The RBD binds with the angiotensin-converting enzyme-2 (ACE-2) found in lungs, heart, kidneys and gastrointestinal tract.


The researchers say that COVID-19 is a mutated version of SARS virus that created an epidemic in 2002-03. Also, the mutation increased their ability to get bonded to ACE-2 enzymes.
