WHO advocates for expanded collaboration, monitoring of COVID variants
The COVID-19 reproduction "R" number in the UK is estimated between 1.0-1.4, the UK Health Ministry said last week.

WHO also advocated for the "prompt" sharing of viral and serum samples globally between nations.“Science and research have played a vital role in responding to the pandemic since day one and will continue to be the heartbeat of everything WHO does,” WHO Director-General Dr. Tedros Adhanom Ghebreyesus said in his welcome speech during the event.The collective consultation worked through six thematic subjects, including epidemiology and mathematical modelling, evolutionary biology, animal models, assays and diagnostics, clinical management and therapeutics and vaccines.The experts decided that there is an importance to focus research on the potential impact of these emerging variants on society, while coordinating the future research across the disciplines - using national data platforms to document critical clinical, epidemiological and viral data working towards facilitating the detection and overall assessment of the new variants, the WHO stated.“Our collective goal is to get ahead of the game and have a global mechanism to quickly identify and study variants of concern and understand their implications for disease control efforts,” said Head of WHO’s R&D Blueprint Dr. Ana Maria Henao Restrepo.Scientists say both the South African and UK variants are associated with a higher viral load, meaning a greater concentration of virus particles in patients' bodies, possibly contributing to increased transmission.The COVID-19 reproduction "R" number in the UK is estimated between 1.0-1.4, the UK Health Ministry said last week, similar to the most recent estimated figure before Christmas.The previous R value, published on Dec. 23, was between 1.1 and 1.3. An R value between 1.0-1.4 implies that for every 10 people that get COVID-19, they will pass it on to between 10 and 14 more.
Genomic sequences for these variants are now being shared worldwide.“So far an astounding 350,000 sequences have been publicly shared, but most come from just a handful of countries. Improving the geographic coverage of sequencing is critical for the world to have eyes and ears on changes to the virus,” said WHO Technical Lead on COVID-19 Dr. Maria Van Kerkhove.
