The WHO raised the alert level to phase 4, meaning there is sustained human-to-human transmission of the virus causing outbreaks in at least one country.

Its alert system was revised after bird flu in Asia began to spread in 2004, and Monday was the first time it was raised above phase 3.

"At this time, containment is not a feasible option," as the virus has already spread to several other countries, said WHO Assistant Director-General Keiji Fukuda.

Putting an alert at phases 4 or 5 signals that the virus is becoming increasingly adept at spreading among humans. That move could lead governments to set trade, travel and other restrictions aimed at limiting its spread.

Phase 6 is for a full-blown pandemic, characterized by outbreaks in at least two regions of the world.


Ask your chemist what level of protective mask is optimal for you. In general any rating better than P2, N95 or FFP2 will stop 95% of airborne water droplets which spread the virus. Drying out the virus or using soap and water will kill it.

Common sense applies when using a face mask. Getting the filter media wet from rain or breath means you have to change masks, and touching the front of a used mask just transfers the viral particles to your hands, which then need to be washed.

the CRG healthcare site seems to have its head on straight when it comes to precautions.

They don't mention some later developments like the viroguard mask

as for me: I'm sticking to the old fashioned P2 mask that we have in the Bio21 supply store for $2.00 a mask and is also available from Bunnings, any chemist or your doctor.
