The World Health Organization (WHO) recommends wearing masks as an important measure to help prevent the spread of SARS-CoV-2, the virus that causes COVID-19. According to the WHO, masks can help to reduce the transmission of the virus by trapping droplets that are released when an infected person speaks, coughs, or sneezes.

The WHO recommends that people wear masks in situations where physical distancing is difficult to maintain, such as in crowded indoor spaces, on public transportation, and in situations where you are in close contact with people who are at high risk of severe illness from COVID-19, such as older adults and those with underlying health conditions.

The WHO also recommends that masks should be made of at least three layers, with the inner layer made of a material that absorbs moisture, such as cotton, a middle layer made of a filter material, and an outer layer made of a water-resistant material. They also advise people to ensure that masks fit snugly and securely over the nose, mouth, and chin, and should not be touched or adjusted once they are in place.

It's important to note that while wearing a mask is an important step in preventing the spread of the virus, it should be used in combination with other measures, such as physical distancing, frequent hand washing, and avoiding crowded indoor spaces.

Omicron and its sub variant what should we know now

The Omicron variant of SARS-CoV-2, the virus that causes COVID-19, is a concern among scientists due to its mutations in the spike protein of the virus. These mutations may make the variant more transmissible and potentially able to evade the immunity provided by some vaccines. Some sub-variants of Omicron have been identified, such as O.1, O.2 and O.3.

It's important to note that more research is needed to fully understand the implications of these mutations and the true level of danger posed by the Omicron variant is not yet fully known. However, some studies suggest that the Omicron variant is more transmissible than previous variants.

To protect yourself and others from the Omicron variant, it is important to follow the guidance of public health authorities, including getting vaccinated if eligible, wearing a mask, practising physical distancing, and washing your hands frequently. It is also important to be aware of any new guidance or recommendations that may be issued as more information about the Omicron variant becomes available.

It's also important to note that the Omicron variant has been found in many countries and likely to be more widespread, so it's important for authorities to have surveillance systems and rapid response plans in place to detect, track, and respond to this variant.
