Proof that masks work against coronavirus

Compiling the knowledge I’ve acquired so far:

Yes, N95 masks DO minimise the chance of getting the virus. Taiwan had planned and got itself fully prepared even as the virus had barely started. They were on the front foot and started mass production. By end February they were producing 4 million masks per day. Now 10 million per day. Plus 120 other actions.

ADDENDUM It remains true that “if people don’t wash their hands before taking off a mask, “you could increase your risk”. Washing hands before putting it on is important, and likewise after washing, since some virus might transmit from the mask to the hands. Hand sanitisers are therefore a crucial part of the mask toolkit.


Claim: ‘Face masks don’t work’

Wearing a face mask is certainly not an iron-clad guarantee that you won’t get sick – viruses can also transmit through the eyes and tiny viral particles, known as aerosols, can penetrate masks. However, masks are effective at capturing droplets, which is a main transmission route of coronavirus, and some studies have estimated a roughly fivefold protection versus no barrier alone (although others have found lower levels of effectiveness).

If you are likely to be in close contact with someone infected, a mask cuts the chance of the disease being passed on. If you’re showing symptoms of coronavirus, or have been diagnosed, wearing a mask can also protect others. So masks are crucial for health and social care workers looking after patients and are also recommended for family members who need to care for someone who is ill – ideally both the patient and carer should have a mask.

However, masks will probably make little difference if you’re just walking around town or taking a bus so there is no need to bulk-buy a huge supply.


The high rate of infection may be blamed, in part, on inadequate hand disinfection and sparse use of N95 respirators, which are designed to filter out virus particles, according to a study posted Feb. 19 on the preprint server medRxiv.


“commonly worn surgical masks are not effective protection”. “A heavy-duty mask, called an N95 respirator, is considerably better protection, but it is uncomfortable and can make breathing more difficult, the radio network said.”


“Masks known as N95 respirators guard against the virus, but only if used properly. Other masks don’t filter out small particles harboring the bug.”


N95 masks offer more protection. But they only work if they fit properly, and aren’t suitable for children or people with facial hair


“Doctors at the largest public hospital in New York say equipment shortages have resulted in them wearing the same masks for as long as a week. [This means that despite concerns, they can be re-used in emergency situations]

Rig Veda provides significant evidence of the “Aryan” invasion

I’m incrementally getting inclined to consider the Aryan invasion theory again. Not just migration.

Parpola’s evidence along with latest DNA evidence is becoming persuasive.

Extract below from Parpola’s The Coming of The Ayrans to Iran and India:

In his book The Roots of Hinduism, Parpola cites the following (rather extensive) extracts from a new translation of Rig Veda to demonstrate the nature of early wars. These are from a new translation of the Rigveda by Stephanie Jamison and Joel Brereton (2014).

1,51,5 With your wiles you blew away the wily ones, who, according to their own customs,
poured (their offering) “on the shoulder.”

You broke through the strongholds of Pipru, O you of manly mind; you helped jiśvan
through in the smashing of Dasyus.

6 You helped Kutsa in the smashing of Śuṣṇa, and you made Śambara subject to Atithigva.

With your foot you trampled down Arbuda, though he was great. Indeed, from long ago you
were born to smash Dasyus.

8 Distinguish between the Āryas and those who are Dasyus. Chastising those who follow no
commandment, make them subject to the man who provides ritual grass.

Become the potent inciter of the sacrificer. I take pleasure in all these (deeds) of yours at our
joint revelries.

1,103,3 He who by nature provides support, being trusted for his power, roved widely, splitting
apart the Dāsa strongholds.

As knowing one, O possessor of the mace, cast your missile at the Dasyu; strengthen Ārya
might and brilliance, O Indra.

2,12,4 By whom all these exploits have been done: who has put the Dāsa tribe below and hidden away,

who has taken the riches of the stranger, as a winning gambling champion does the wager— he, O peoples, is Indra.

10 Who has struck with his arrow those constantly creating for themselves great guilt, the unthinking ones;

who does not concede arrogance to the arrogant man; who is the smasher of the Dasyu— he, O peoples, is Indra.

11 Who in the fortieth autumn discovered Śambara dwelling in the mountains;

who smashed the serpent displaying its strength, the son of Dānu, (thereby) lying (dead)—he, O peoples, is Indra.

2,20, 6 The god famed as Indra by name, he the most wondrous, rose upright for Manu.

The able, independent one carried away the Dāsa Arśasāna’s very own head.

7 Smasher of Vtra, splitter of fortresses, Indra razed the Dāsa (fortresses) with their dark wombs.

He gave birth to the earth and the waters for Manu. In every way, he makes the sacrificer’s laud powerful.

4,16,10 Drive here to the home (of Uśanā Kāvya) with your Dasyu-smashing mind. In companionship with you, Kutsa will become eager.

Do you two, having the same form, sit down each in his own womb. She is trying to distinguish between you two—she is a woman who distinguishes the truth.

12 For Kutsa you laid low insatiable Śuṣṇa, who brings bad harvest, with his thousands, before the day’s first meal.

Immediately crush out the Dasyus with (the weapon) that is Kutsa, and then tear off the wheel of the Sun at the moment of encounter.

13 You subjugated Pipru Mgaya, swollen with power, to jiśvan, the son of Vidathin.

You scattered down the dark fifty thousand. You shredded their fortresses, like worn-out age a cloak—

5,34,6 Very energetic in the clash, affixing the wheel (to the chariot?), he is antagonistic to the non-presser, but strengthener of the presser.

Indra is the dominator of all, spreading fear; the Ārya leads the Dāsa as he wishes.

6,20,10 Might we win anew through your help, Indra. The Pūrus start up the praise with this (hymn) along with sacrifices.

When he split the seven autumnal strongholds, their shelter, he smote the Dāsa (clans), doing his best for Purukutsa.

6,26,5 You made that hymn (endowed) with might, Indra, so that you could tear out hundreds and thousands (of goods), o champion.

You struck the Dāsa Śambara down from the mountain and furthered Divodāsa with glittering help.

6,47,21 Day after day he drove off from their seat the other half, the black kindred all of the same appearance.

The bull smashed the two Dāsas, mercenaries, Varcin and Śambara, at the moated place.

7,6,3 Down with those of no intelligence, those tying in knots, those of disdainful words: the Pais, not giving hospitality, not giving strength, not giving sacrifices.

Onward and onward Agni has pursued those Dasyus. The first has made the last to be without sacrifices.

7,19,2 Just you, O Indra, helped Kutsa, while seeking fame for yourself with your own body in the clash,

when for him you weakened the Dāsa Śuṣṇa bringing bad harvest, doing your best for Arjuna’s offspring.

4 You—whose mind is inclined towards men in their pursuit of the gods—along with men you smash many obstacles, you of the fallow bays;

you put to sleep the Dasyu Cumuri and Dhuni, easy to smash, for Dabhīti.

5 Yours are these exploits, you with the mace in hand—that nine and ninety fortifications at once

along with the hundredth you worked to the end, in bringing them to rest [= collapse]. You smashed Vtra, and moreover Namuci you smashed.

8,70,10 You are the one who seeks the truth for us, Indra. You find no satisfaction in him who reviles you.

Gird yourself in between your thighs, O you of mighty manliness. Jab down the Dāsa with your blows.

11 The man who follows other commandments, who is no son of Manu, no sacrificer, no devotee of the gods—

him should your own comrade, the mountain, send tumbling down; the mountain (should send down) the Dasyu for easy smiting.

10,22,8 The Dasyu of non-deeds, of non-thought, the non-man whose commandments are other, is against us.

You smasher of non-allies, humble the weapon of this Dāsa.

10,138,3 The sun unhitched his chariot in the middle of heaven. The Ārya found a match for the Dāsa.

The firm fortifications of the crafty lord Pipru did Indra throw open, having acted together with jiśvan.

4 Defiant, he threw open the undefiable (fortifications); the unbridled one pulverized the ungodly treasure-houses.

Like the sun with the moon, he took for his own the goods found in the fortress. Being sung, he shattered his rivals with his flashing (weapon).
