The present invention provides the use of nanoparticles of a compound of general formula MX, where M is (i) a metal selected from the group consisting of Calcium (Ca), Aluminium (Al), Zinc (Zn), Nickel (Ni), Tungsten (W) or Copper (Cu); or (ii) a non-metal selected from the group consisting of Silicon (Si), Boron (B) or Carbon (C); in which n is equal to 1, 2, or 3, and X is (iii) a non-metal selected from the group consisting of Oxygen (O), Nitrogen (N), or Carbon (C); or (iv) an anion selected from the group consisting of phosphate (PO), hydrogen phosphate (HPO), dihydrogen phosphate (HPO), carbonate (CO), silicate (SiO), sulphate (SO), nitrate (NO), nitrite (NO); in which y is equal to 0, 1, 2, 3 or 4; for use in reducing and/or preventing virus transmission. Articles of protective clothing or filters are provided in which the fibres are coated with said nanoparticles for use in reducing and/or preventing virus transmission. 2. A use as claimed in claim 1 , in which the nanoparticles have an average particle size up to 100 nm.3. A use as claimed in claim 2 , in which the nanoparticles have an average particle size in a range of from about 1 nm to about 90 nm4. The use as claimed in claim 1 , in which the compounds of the general formula MXare oxides claim 1 , carbonates claim 1 , silicates claim 1 , carbides claim 1 , nitrides and/or phosphates.5. The use as claimed in claim 4 , in which the compounds of the general formula MXare selected from the group consisting of aluminium oxide (AlO) claim 4 , silicon dioxide claim 4 , (SiO) claim 4 , zinc oxide (ZnO) claim 4 , aluminium phosphate (AlPO) claim 4 , aluminium hydrogen phosphate (Al(HPO)) claim 4 , aluminium dihydrogen phosphate (Al(HPO)) claim 4 , calcium oxide (CaO) claim 4 , calcium carbonate (CaCO) claim 4 , calcium silicate (CaSiO) claim 4 , calcium phosphate (Ca(PO)) claim 4 , calcium hydrogen phosphate (CaHPO) claim 4 , or calcium dihydrogen phosphate (Ca(HPO) claim 4 , silicon nitride (SiN) claim 4 , ...
