• In response to COVID-19, WHO published the "Strategic Preparedness and Response Plan" that outlines the health measures that should be taken in order to prevent the spread of COVID, as well as guidelines the international community and governments should follow to provide support and an outline for countries to prepare for and respond to COVID-19. The document discusses all the information WHO has about the virus and puts that knowledge into strategies and tactics that can help guide governments and international partners when creating context-specific, operational plans.

The US is currently halting payments to the WHO and has decided to pull out of the organization which could take effect as early as July 2021. Trump claims that the WHO was completely under China's control in the wake of COVID-19 and that the Chinese had instigated this global pandemic. In late May he said: "We will be terminating our relationship with the World Health Organization and directing those funds" to other global public health charities. The US was the top contributor in 2018-19 with $893 million. The abrupt leave could cause other members to follow in the US's footsteps and pull out of the organization too which would cause the WHO to lose a lot of power over global health authority.

The WHO has been able to provide health assistance to less fortunate countries who struggle with health issues but do not have the resources to combat these issues due to poverty and lack of governmental assistance.

WHO also allows and control the fair/equal distribution of pharmaceutical products (vaccinations, drugs etc) that allow for the development and improvement of health issues.

The WHO has had many positive effects on governments and has developed and improved the way global issues regarding health are acted upon by all nations. (i.e. COVID 19)

The WHO work to develop better health policies and use funds to ensure that health is prioritized with overall economic/development plans.

The WHO has affected the way pandemics and global health issues are dealt with and has allowed for the health sector to be more productive and effective around the world in developed and under-developed countries.
