The states of Illinois, Kentucky, Mississippi, North Carolina, Oklahoma, Tennessee, Texas, and Vermont did not notify the Center for Disease Control regarding cases in 2018. The states with the highest number of cases in 2018 were California, New York, Florida, and Wisconsin. There are seasonal trends associated with giardiasis. July, August, and September are the months with the highest incidence of giardiasis in the United States.In the ECDCs (European Centre for Disease Prevention and Control) annual epidemiological report containing 2014 data, 17,278 confirmed giardiasis cases were reported by 23 of the 31 countries that are members of the EU/EEA. Germany reported the highest number at 4,011 cases. Following Germany, the UK reported 3,628 confirmed giardiasis cases. Together, this accounts for 44% of total reported cases. Research
Some intestinal parasitic infections may play a role in irritable bowel syndrome and other long-term sequelae such as chronic fatigue syndrome. The mechanism of transformation from cyst to trophozoites has not been characterized but may be helpful in developing drug targets for treatment-resistant Giardia. The interaction between Giardia and host immunity, internal flora, and other pathogens is not well understood.The main congress about giardiasis is the "International Giardia and Cryptosporidium Conference" (IGCC). A summary of results presented at the most recent edition (2019, in Rouen, France) is available. Other animals
In both dogs and cats, giardiasis usually responds to metronidazole and fenbendazole. Metronidazole in pregnant cats can cause developmental malformations. Many cats dislike the taste of fenbendazole. Giardiasis has been shown to decrease weight in livestock. References

The FDA has approved the use of lasers in the treatment of many disorders. The treatment of GSM is not specifically mentioned in the list of disorders by the United States Food and Drug Administration (FDA) but laser treatments have had success. Larger studies are still needed. The laser treatment works by resurfacing the vaginal epithelium and activating growth factors that increases blood flow, deposition of collage and the thickness of the vaginal lining. Women treated with laser therapy reported diminished symptoms of dryness, burning, itching, pain during sexual intercourse, and painful urination. Few adverse effects were noted.In 2018, the FDA issued a warning that lasers and other high energy devices were not approved for this application and it had received multiple reports of injuries.
