A global emergency is WHO’s highest level of alert but the designation does not necessarily mean a disease is particularly transmissible or lethal. Similar declarations were made for the Zika virus in 2016 in Latin America and the ongoing effort to eradicate polio, in addition to the COVID-19 pandemic and the 2014 Ebola outbreak in West Africa.
WHO Director-General Tedros Adhanom Ghebreyesus made the decision on calling monkeypox a global emergency despite a lack of consensus among experts on the U.N. health agency’s emergency committee, saying he acted as “a tiebreaker.” It was the first time a U.N. health agency chief has unilaterally made such a decision without an expert recommendation.
The WHO did not declare it a global emergency. One person did by himself.
This is why people lose confidence in "science" because even the people in charge of those areas replace scientific analysis, measurements and long-established guidelines and policies with their own arrogant subjective opinions and theories and assume due to having their job title people will believe them.
To be clear, I am not debating whether or not this is a global emergency but simply pointing out that in a world where every statement, scientific or not, is over-analyzed, heavily scrutinized and wildly debated, the last thing the scientific community should be doing is declaring and disseminating opinions and educated guesses under the guise of factual information.
That leads to distrust which opens the door for misinformation and disinformation and once that happens, it is hard to gain back the trust of the people.
