![]() Small red pinprick spots on the skin are a relatively common condition, but the underlying causes behind them can vary. If you experience this condition, it is always recommended to consult with a medical professional to determine the underlying cause and discuss potential treatment options. Pinpoint red dots or petechiae can have various causes ranging from injuries, infections, blood disorders, and genetic conditions. There are also instances where certain medications can cause petechiae as a side effect. In these cases, individuals may be born with small blood vessels that are more prone to bursting. In rare cases, petechiae can occur as a genetic condition. Other blood disorders such as leukemia, a type of cancer that affects the bone marrow, can also cause petechiae. This can result in petechiae and other symptoms such as easy bruising and bleeding. For example, thrombocytopenia is a condition that occurs when there is a decrease in the number of platelets in the blood. Medical conditions that affect the blood can cause petechiae. ![]() Certain viral diseases, such as chickenpox, measles, and hepatitis, are known to cause petechiae as well. This can be due to bacterial or viral infections, such as meningitis or sepsis. Infections are also known to cause petechiae. This can also occur from excessive coughing, vomiting or sneezing, which can increase the pressure inside the blood vessels and cause them to burst. Injury or trauma to the skin can cause tiny blood vessels, or capillaries, to burst, leading to the appearance of petechiae. The most common causes of petechiae are related to injuries, infections, or underlying medical conditions such as thrombocytopenia, leukemia, and lupus. Petechiae can be caused by a variety of factors, including medical conditions, genetics, and lifestyle choices. They are typically about the size of a pinpoint or a tiny freckle and can occur anywhere on the skin.

Other studies have suggested such a relationship, he said, but this new research provides the first clear link between internet activity and disease prevalence. Referring to Kutera’s mapping of trends, Berke said, “There was a signal for searches with Lyme diseases that overlapped with where people had been more often infected with Lyme disease.” Their paper appeared recently in the journal Environmental Health Review. The study involved first author Maria Kutera, a fourth-year undergraduate student in biological science, and PhD candidate Kurtis Sobkowich. ![]() ![]() The same area showed more frequent internet searches for terms such as “Lyme disease,” “ticks” and “tick bites” than other parts of the province. They found that most infections occurred in eastern Ontario, between Prince Edward County and the Ontario-Quebec border. The researchers then compared that information with Google Trends data for the same regions and years. The team looked at reports of Lyme disease from 28 public health units in southern Ontario between 20. ![]() It’s the most reported vector-borne disease in the United States and is Canada’s most common tick-borne illness Lyme disease is caused by the bacterium Borrelia burgdorferi and transmitted by blacklegged ticks, which have moved into central and eastern Canada in recent years. “If we know from Google Trends that in certain areas there are these ticks, then physicians might take that into account in diagnosing infection.” “When people search online for a problem, chances are there is a problem,” he said. Olaf Berke, in photo at left, a statistical epidemiology professor in the Department of Population Medicine in the OVC. A new study from researchers at the University of Guelph’s Ontario Veterinary College (OVC) tracking Google searches for terms like “Lyme disease” and “ticks” may improve diagnosis and prevention of Lyme disease.Īs the disease continues to spread in Canada, t his first-ever study linking internet search activity with local infection rates may give public health units a tool to monitor that spread and warn people about Lyme hot spots, said Dr. ![]()
