Regarding the Washington Post article, “The more we learn, the worse things seem to get”: With 160 confirmed cases in Puerto Rico and thousands of pregnant women expected to be infected by the end of the year, it is time for Congress to act. With the cost of caring for one child with birth defects at $10 million or more, prevention is much cheaper. Whether it is Zika, Ebola, HIV or tuberculosis, it will be cheapest to deal with it now. As Mark Dybul of the Global Fund has said, we are at a tipping point to control these diseases or watch these diseases explode out of control. So calls and letters will help Congress, decide to act now.
