British holidaymakers visiting Mexico are being warned about an intestinal parasite that is ravaging resorts in the country.  A total of 14 tourists staying at luxury hotels in the Riviera Maya resort and Cancun have experienced crippling stomach pains, sickness and diarrhoea due to an illness that is passed on through contaminated food.  The cause of the illness is the _Cyclospora cayetanensis_ parasite, which is transmitted by faeces coming into contact with water and food. This the 5th year in a row that the parasite has infected tourists in the region.

Nearly 600 British people have been infected with the bug since 2015, and the same areas of Mexico were the subject of a public health warning 3 years ago. Now medical experts are advising anyone who has visited the affected resorts and is feeling ill to seek medical attention.  Advice on the Health Protection Scotland website reads, "All travellers to Mexico are strongly advised to maintain a high standard of food, water and personal hygiene even if staying in luxury resorts. "Infection is transmitted through consumption of contaminated food or water; direct person to person spread does not occur. Foods often implicated in outbreaks include soft fruits like raspberries and salad products such as coriander, basil and lettuce. "On return from Mexico, if travellers have any symptoms such as those described above, they should seek medical attention."

A spokesperson for Health Protection Scotland confirmed an outbreak of _Cyclospora_ in Mexico, stating, "There have been seasonal outbreaks of _Cyclospora_ infection in returning travellers from Mexico over the past 4 years.  "The majority of cases stayed at the Riviera Maya and Cancun regions of Mexico. Health Protection Scotland is aware of 8 cases in Scotland this year [2019] with a history of travel to Mexico. "_Cyclospora_ infection can cause diarrhoea and illness. The infection can be more serious in individuals with an impaired immune system. Prevention is through following good food and water hygiene practices at all times while on holiday."  [Byline: Lloyd Bent]

[Products originating from Mexico have been behind several multistate outbreaks of cyclosporiasis in the USA and Canada and are currently the source of an multistate outbreak in the USA (see ProMED posting from the 27 Jul 2019 below).

Cyclosporiasis has also been reported in tourists returning from Mexico to the UK, France and Canada (see ProMED reports below). Therefore, it is not surprising that there is a current increase in cases at the same time as the outbreak in the USA. - ProMED Mod.EP]

Guadalajara, Mexico, July 1, 2019 (AFP) - A freak hail storm on Sunday struck Guadalajara, one of Mexico's most populous cities, shocking residents and trapping vehicles in a deluge of ice pellets up to two meters (yards) deep.   "I've never seen such scenes in Guadalajara," said the state governor, Enrique Alfaro.   "Then we ask ourselves if climate change is real. These are never-before-seen natural phenomenon," he said. "It's incredible."

Guadalajara, located north of Mexico City and with a population of around five million, has been experiencing summer temperature of around 31 Centigrade (88 Fahrenheit) in recent days.   While seasonal hail storms do occur, there is no record of anything so heavy.

At least six neighbourhoods in the city outskirts woke up to ice pellets up to two meters deep.   While children scampered around and hurled ice balls at each other, Civil Protection personnel and soldiers brought out heavy machinery to clear the roads.   Nearly 200 homes and businesses reported hail damage, and at least 50 vehicles were swept away by the deluge of ice in hilly areas, some buried under piles of pellets.   While no casualties were reported, two people showed "early signs of hypothermia," the state Civil Protection office said.

Floodwaters in Reynosa.

The toll from a rainstorm that hit the city of Reynosa on Monday night is two deaths and 57 flooded neighbourhoods, authorities say.  The intense rains flooded thousands of homes across the Tamaulipas border city, and in some places floodwaters were over a meter and a half deep. United States authorities had warned that the storm could affect cities in the Río Grande Valley. But Mexico’s National Meteorological Service had only forecast moderate to intense rains.

As the water began to rise, the army responded to rescue people from their homes. A total of 92 people were taken to temporary shelters set up in the municipal auditorium, the stadium and the Rodhe campus of the Autonomous University of Tamaulipas.  The rains also damaged Reynosa’s electrical grid, leaving 100,000 people without power for 12 hours.

Governor Francisco Javier García Cabeza de Vaca said that municipal governments need to take measures to prevent similar flooding from happening again.  “When the hurricane season started, we were working with Civil Defense in the state, and they recommended that every municipal government should work on preventative measures, especially cleaning out drains,” he said. “Because when drains are full of trash, the water level rises, and it leads to flooding.”

The California Department of Public Health (CDPH) says oysters harvested from Baja California Sur, Mexico are linked to a gastrointestinal illness outbreak in California. The CDPH said 12 people between [February and April 2019] have reported getting sick after eating raw oysters from stores and restaurants in San Diego County, Los Angeles County, Orange County, and Santa Barbara County.

The investigation is ongoing, but so far, laboratory testing of oysters harvested from Estero El Cardon revealed 6 different toxic pathogens, including non-O157 Shiga toxin-producing _E. coli_. Mexican authorities are also investigating.

The CDPH says shellfish sold at stores and restaurants is required to have tags indicating where the product is from. People who become ill after eating raw oysters or undercooked shellfish should contact a doctor, the CDPH says. The CDPH also says shellfish should be cooked to at least 145 degrees Fahrenheit internal temperature. The department also warns against quick steaming.  [Byline: Rafael Avitabile]

Authorities in Veracruz report that 1358 people were admitted to emergency rooms on Children's Day after contracting food poisoning. Health officials said the Zongolica, Tlaquilpa, and Rio Blanco regional hospitals looked after 699 of the intoxicated adults and children, while 433 were admitted at the IMSS [Mexican Social Security Institute] clinics in Atlahuilco and Tehuipango. Another 186 received medical care at the health centers in Tilica and Alcomunga, Puebla, while 40 were taken to private medical institutions.

While most of the victims were in no danger after receiving outpatient oral rehydration, some severe cases required intravenous fluid regulation. Lab results are expected in 3 to 4 days and will enable authorities to determine the cause of intoxication.

At the same time, the state government announced that it will be proceeding legally against World Vision, organizer of the annual event. Preliminary reports indicate that children began feeling ill after eating cake. Education Secretary Zenyazen Escobar Garcia told reporters that the massive food poisoning could have been "tragic," and that Governor Cuitlahuac Garcia Jimenez had ordered that action be taken against the aid organization.

World Vision said in a statement later the same day that it was fully prepared to work with authorities to investigate the source of the poisoning and promised medical aid to victims. The organization, which said it had been involved in the Children's Day event for 10 years, said it was "deeply concerned" over the incident.  There were also cases of Children's Day food poisoning in Guerrero.
==========================
[The exact symptoms that occurred are not clear nor is the incubation period to the development of illness stated. If cake was the vehicle, icing on the cake or custard filling may be involved as the cause, likely to be staphylococcal enterotoxin related. ProMED awaits the results of the additional laboratory testing. - ProMED Mod.LL]
