  • Surveillance is an incredibly important tool in monitoring virus incidence and disease spread. Here is a summary of an article published in the National Library of Medicine that explains it in detail:

    “Surveillance is a fundamental tool for public health, producing information to guide actions. Modern surveillance tends to follow health measures such as the incidence of a disease or syndrome or even the occurrence of health-related behaviors. There are many reasons for conducting surveillance, and the data collected and the approach taken to analyzing those data are both influenced by the overall goal of a surveillance system. Surveillance systems aims mainly at detection also provide information that may be useful for other purposes. The goal of detecting an outbreak of a newly emerging virus, places specific demands on the type of data collected and the types of analysis performed. All approaches to surveillance share some common principles. While some of the underlying methods used in public health surveillance have evolved considerably in recent years, the general approach to surveillance has remained relatively constant. At a fundamental level, surveillance aims to (1) identify individual cases, (2) detect population patterns in identified cases, and then (3) convey information to decision-makers about population health patterns.”

    The rabies virus is shed in saliva. More than 99% of all rabies cases (of which there are about 50,000 a year) are due to the transmission of the virus from the saliva of an infected animal/human into the bloodstream of another human.

    The website linked mentions “it has been reported” that rabies can be transmitted via intercourse, but doesn’t cite any papers that state as such. Likely the only way this could work is if a human with rabies performs oral sex on another person, creates micro-abrasions on the genital tissue of their partner while shedding the virus in their saliva which infects the 2nd person.

    So while it might be technically possible, rabies doesn’t meet the criteria of what we typically refer to as STDs or STIs with our current knowledge and understanding of the disease.


  • Unless you are a small hobby farm, you’re not putting your cows out on pasture alone to raise them for meat. Most grasses are deficient in one or more vital nutrients that the cows need to grow. Most cows today are fed TMR (Total Mixed Rations). These are diets carefully mixed with different grasses, grains, hays, and mineral supplements. There are different metabolic diseases that cows can get when eating diets deficient in different nutrients. Cows that are sick don’t want to eat, and cows that don’t eat don’t grow. To a farmer, that’s like burning money.
