[Compiled by Chen Chengliang/Comprehensive Report]Qu Gong disease is a disease transmitted by vector mosquitoes. It is afflicting the population of more than half of the world’s countries and there is a risk of further spread. According to a report in the journal Science, the world’s first vaccine against schizophrenia will soon be approved by the U.S. Food and Drug Administration (FDA) and is expected to be launched in December.
According to the report, the vaccine that is about to be approved is developed and produced by the French biotechnology company Valneva, and may initially be recommended mainly to American tourists traveling to affected areas. It is expected that the FDA’s approval will also pave the way for the vaccine to be launched in other countries.

Chikungunya Fever was first recorded in Tanzania in 1952. In the Kimakonde language of East Africa, Chikungunya means “curvature of the joints.” Although the disease is rarely fatal, TCM virus can cause long-term, debilitating joint pain in up to 40 percent of people infected. Most of these infected people live in warm areas where there are large numbers of Aedes aegypti and Aedes albopictus mosquitoes. In the United States, nearly all cases are among travelers returning from endemic countries.
Valneva’s research shows that 99% of people who receive one dose of the vaccine develop long-lasting antibodies. If the vaccine is approved, the FDA will require Valneva to conduct post-market clinical studies to evaluate whether the vaccine can actually prevent disease in the real world.
The global epidemic of TCM is mainly distributed in tropical and subtropical regions such as sub-Saharan Africa, Asia and South America. In recent years, due to factors such as economic and trade development and population migration, the endemic areas have gradually expanded. In addition, analysis of this circulating virus shows that the virus has mutated and can easily replicate itself in Aedes albopictus and Aedes aegypti mosquitoes, exacerbating its transmissibility to humans. In recent years, the epidemic has quickly broken out in India, Thailand, the Caribbean, and Brazil. So far, more than 100 countries have reported local transmission of the virus.
The early symptoms of TCM are very similar to those of dengue fever and Zika virus infection. Most people infected with TSV have symptoms, including sudden fever, joint pain or arthritis (about 70% of patients have it, especially the small joints of the hands and feet, wrists and ankles), headache, nausea, vomiting, fatigue, muscle pain or rash ( Approximately half of patients will experience it), and may be accompanied by atypical symptoms such as conjunctivitis, diarrhea, and photophobia, and the symptoms last for about 3 to 7 days. Fatal cases from TKD are rare, and most patients recover within 7 to 10 days. A few patients experience severe joint pain from the onset of the disease, which lasts for several months.
