Lupus cases are not reported to any agency.
Lupus statistics are hard to pin point in any country. For example, in the United States, a diagnosis of lupus is not reported to any statistic gathering agency. Statistics are based on population samples (questionnaires) and hospital discharges. The Centers for Disease Control do not track lupus. Even if lupus cases are reported to a central agency in China, that data is not published.
Since lupus is not an infectious disease there is no agency to which a diagnosis is reported. The Lupus Foundation of America estimates that 16,000 patients are diagnosed in America each year.

Lupus statistics for the number of children worldwide with lupus are not available. Since lupus is not a contagious disease, there are no reporting requirements to any agencies that gather this data. In developing countries, many people do not have access to doctors who can properly diagnose the disease, so many cases go undiagnosed. Some lupus statistics are drawn from hospital discharge statements, however, the discharge statement might not reflect the diagnosis. Doctors have no agency to which to report cases of lupus. Some data, like that of the Lupus Foundation of America, is based on telephone surveys and extrapolated to the general population. There really is no answer to your question.
