In looking for alternative explanations other than illegal substances, I came across this information about the presence of West Nile in San Jose. It was a serious enough concern that it looks like extensive spraying/fogging had been done fairly recently in Santa Clara County in late July.
The impact of some of these infected mosquitoes can be deadly. In CT, I believe 3 people have died of EEE infection (not West Nile but another potentially deadly disease). There have been a total of 12 human cases of EEE infection in Massachusetts, including three fatalities, and three human cases in Rhode Island, including one fatality.
We have the statements from the family that what they experienced on the phone from EV was out of character and I respect them and their knowledge of the victim in this case and absent a toxicology report, which depending on the substances tested for could take up to 6-8 weeks in a busy lab, I am unwilling to speculate on the possible impact of illegal substances.
West Nile Virus Positive Mosquitoes Detected in San José and Campbell - County News - County of Santa Clara
West Nile Virus - Vector Control District - County of Santa Clara
Quotes from Bulletin:
The Santa Clara County Vector Control District (SCCvcd) has confirmed that adult mosquitoes collected from the 95117, 95128, 95008, 95050 ZIP code areas of the cities of San José and Campbell have tested positive for West Nile virus (WNV). The detection of mosquitoes infected with WNV has prompted the scheduling of a mosquito fogging treatment in the surrounding areas in an effort to prevent human cases of WNV. Weather permitting, the ground fogging operations are scheduled for
11 p.m. on Thursday, July 21, and will conclude a few hours later.
Health Effects of West Nile Virus
Since the arrival of WNV to California in 2003,
5,588 people across the State have contracted the disease;
229 of those cases
were fatal. 2015 was a record year for fatalities in the state with 53 deaths.
WNV infection does not cause symptoms in most people, but in some individuals it can cause fever, headache, body aches, and in severe cases, significant neurological damage or death. Adults older than 50 years and individuals with certain chronic medical conditions such as diabetes, high blood pressure, cancer, and kidney disease are most at risk for serious complications.
