On January 28, 2020, the CDC updated its China travel recommendations to level 3, its highest alert. On February 8, the WHO’s director-general announced that a team of international experts had been assembled to travel to China and he hoped officials from the CDC would also be part of that mission. In January, Boeing announced a donation of 250,000 medical masks to help address China’s supply shortages. On February 7, the State Department said it had facilitated the transportation of nearly eighteen tons of medical supplies to China, including masks, gowns, gauze, respirators, and other vital materials. On the same day, U.S. Secretary of State Pompeo announced a $100 million pledge to China and other countries to assist with their fights against the virus.
Contact tracing is a tool to control transmission rates during the reopening process. Some states like Texas and Arizona opted to proceed with reopening without adequate contact tracing programs in place. Health experts have expressed concerns about training and hiring enough personnel to reduce transmission. Privacy concerns have prevented measures such as those imposed in South Korea where authorities used cellphone tracking and credit card details to locate and test thousands of nightclub patrons when new cases began emerging. Funding for contact tracing is thought to be insufficient, and even better-funded states have faced challenges getting in touch with contacts. Congress has allocated $631 million for state and local health surveillance programs, but the Johns Hopkins Center for Health Security estimates that $3.6 billion will be needed. The cost rises with the number of infections, and contact tracing is easier to implement when the infection count is lower. Health officials are also worried that low-income communities will fall further behind in contact tracing efforts which “may also be hobbled by long-standing distrust among minorities of public health officials”. As of July 1, only four states are using contact tracing apps as part of their state-level strategies to control transmission. The apps document digital encounters between smartphones, so the users will automatically be notified if someone they had contact with has tested positive. Public health officials in California claim that most of the functionality could be duplicated by using text, chat, email, and phone communications.
