That&#8217;s a <em>huge<\/em> incentive to get the numbers right. If anything, some sites are known to overreport their cases, which is why name-based reporting is such an important accuracy check on the data.<\/p>\n<p>Lest you think that HIV is different because, well, it&#8217;s HIV, believe me there are plenty of places where HIV reporting is woefully inaccurate. Back in the mid-1990s, I joined a group from the Harvard School of Public Health to participate in a scientific symposium on HIV in India. There was a reported explosion of HIV cases in certain regions of the country, and their doctors and researchers set up the conference to address this growing problem.<\/p>\n<p>The first presentation was from a public health official representing the government. He showed data demonstrating that the number of cases in India was still relatively small and confined to isolated regions and &#8220;risk groups&#8221; &#8212; mostly commercial sex workers and injection drug users.<\/p>\n<p>The next presentation was from an active ID clinician at one of the largest hospitals in Mumbai. He showed slide after slide demonstrating the ravages of advanced AIDS in diverse populations (emphatically <em>not<\/em> all commercial sex workers and IDUs) and then finished with a few data slides on cases at his hospital. Turns out that <em>he had seen as many cases at his one site as had been officially reported to the government from the entire country.<\/em><\/p>\n<p>When asked how to reconcile his volume of experience with the previous lecture on the national epidemiology, he responded with two other questions.<\/p>\n<blockquote><p>So why should we report our cases? What good does it do us or our patients?<\/p><\/blockquote>\n<p>Once we can answer those questions for Lyme &#8212; as we most certainly can with HIV &#8212; then the underreporting problem will be solved.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In a welcome update, CDC just presented revised data on the number of Lyme Disease cases annually in the United States.
