Do face masks work against the virus?

4 April 2020

Since the beginning of the crisis, we have all been aware of the shortage of face masks, but do they really work? As the US Centers for Disease Control and Protection formally recommends wearing masks to the public, William Murray clears up some common misconceptions in this short article for commonspace.eu.

Over the last few weeks, there has been a level of confusion regarding the value of face masks, with some spreading that they are of no help whatsoever at preventing the spread of the virus. This simply isn't true. Whilst they aren't 100% effective, they are able to block many of the little droplets released in the breath, which is considered the most effective way for the virus to spread [1].

But should you wear a face mask? In the US, this week, officials have recommended the use of face masks to the general public [2]. The World Health Organization, however, has been clear that the only people that should be wearing face masks are those that are sick or taking care of someone that is sick [3]. The BBC have reported that this to prevent the unnecessary touching of the face - removal of the mask needs to be done properly to be effective - and to avoid people being lulled into a false sense of security. [5] In any case, having a face mask is not a substitute for social distancing.

For those looking to make their own masks at home, NBC reports some fabrics work better than others [5].

Borrell tells the European Parliament that the situation in Afghanistan was critical, but the EU will remain engaged

Borrell underlined that the European Union will make every effort to support the peace process and to remain a committed partner to the Afghan people. "Of course, we will have to take into account the evolving situation, but disengagement is not an option.  We are clear on that: there is no alternative to a negotiated political settlement, through inclusive peace talks.

Armenia and Azerbaijan edge closer to a peace deal

22 April 2024
Armenia and Azerbaijan last week announced they had agreed on the process of demarcation of their border in the Tavush region that will result in the return of four villages that had been under Armenian control since the conflict in the 1990s to Azerbaijan. The agreement is being seen as a milestone event that will greatly contribute to finalising the process leading towards the signing of a peace agreement between the two countries, who have been in conflict for more than three decades. The agreement comes after months of negotiations, and controversy, including some opposition from Armenian residents in the proximity of the four villages. On 19 April, it was announced that the eighth meeting of the Committee on Demarcation and Border Security of the State Border between the Republic of Armenia and the Republic of Azerbaijan and the State Committee on the Demarcation of the State Border between the Republic of Azerbaijan and the Republic of Armenia was held under the chairmanship of Armenian Deputy Prime Minister Mher Grigoryan and Azerbaijani Deputy Prime Minister Shahin Mustafaev. There are of course many small details that will have to be ironed out later, but the fact that the sides have agreed the basic parameters, and especially their re-affirmation that they will "be guided by Alma Ata's 1991 Declaration in the demarcation process" is a huge step forward. No wonder that the international community in the last few days have lined up to congratulate the two sides on their success and to nudge them forward to complete the process of signing a peace agreement between them. Seasoned observers now see the signing of such an agreement as being truly within reach. Of course, there will be those who for one reason or another will not like these developments and will try to spoil the process. Armenia and Azerbaijan must remain focused on overcoming any last obstacles, and on its part, the international community must also remain focused in helping them do so as a priority.
