San Diego County Detects First Local Case of Chagas Disease

San Diego County health officials announced the region's first locally acquired case of Chagas disease, found through routine blood donor screening from an asymptomatic donor. Chagas is caused by the parasite Trypanosoma cruzi and spread by kissing bugs; local transmission is now recognized in parts of the United States. The county began requiring reporting in 2024, and this case marks the first acquired locally in San Diego. Public health guidance emphasizes prevention (protective clothing, insect repellent, indoor sleeping, treated nets) and screening for at-risk groups, including pregnant women, with researchers suggesting the disease may be more common in the U.S. than previously thought.

New York Sees First Local Case of Rare Lyme Bacterium Borrelia mayonii

CDC confirms the first local detection of the Lyme-disease bacterium Borrelia mayonii in New York: a Herkimer County resident tested positive and ticks on the property carried the bacterium, with nine additional B. mayonii–positive adult ticks found later, suggesting local transmission likely involving wildlife. Nationwide testing found no other NY cases. B. mayonii is distinct from the more common Borrelia burgdorferi, though symptom differences are not well understood. The patient also had anaplasmosis and recovered after doxycycline treatment.

Nassau County Resident Reports First Local Chikungunya Case in NY

New York has confirmed its first locally acquired case of chikungunya virus in six years, detected in Nassau County, though there is no evidence of ongoing transmission. The virus, spread by mosquitoes, is rare in the U.S., with most cases linked to international travel. The current risk of spread is very low due to cooler fall temperatures, and the disease typically causes mild symptoms, though vulnerable populations are at higher risk.

"Dengue Outbreak Hits California: 2 Confirmed Cases of Rare Mosquito-Borne Illness"

Two cases of dengue fever have been confirmed in Southern California, marking rare instances of local transmission in the continental United States. The infected individuals did not travel outside the country, suggesting that they were bitten by mosquitoes carrying the virus within the US. Dengue fever, caused by infected Aedes mosquitoes, is common in tropical areas and can lead to high fevers, headaches, and in severe cases, internal bleeding. While dengue is rare in the US, efforts to combat the infection are increasing worldwide.

"Dengue Virus Spreads Locally in California, Rare Cases Confirmed"

Health officials in California have confirmed two cases of dengue fever, a mosquito-borne illness, in individuals who did not travel outside the United States. This is an extremely rare occurrence of local transmission in the continental US. The cases, one in Pasadena and another in Long Beach, are under investigation, but it is believed that the individuals were infected with the dengue virus after being bitten by mosquitoes in their local areas. Dengue fever is common in tropical regions and can cause high fevers, headaches, muscle pain, and in severe cases, internal bleeding. The risk of exposure to others is considered low.

"Dengue Virus Spreads Locally in California, 2nd Case Confirmed"

Two cases of dengue fever, a mosquito-borne illness, have been reported in California, with both individuals claiming they haven't traveled outside the United States. This is an extremely rare occurrence of local transmission within the continental U.S. Symptoms of dengue fever include severe abdominal pain, persistent vomiting, and in severe cases, internal bleeding leading to death. Dengue is common in tropical areas and affects about half the world's population, causing millions of infections and thousands of deaths each year. The most dangerous aspect of dengue fever is the risk of reinfection, with symptoms often worsening the second time around. Health officials advise seeking medical attention immediately if experiencing symptoms, especially for those who have had dengue fever before.

"Rapid Spread of Disfiguring Tropical Disease Alarms CDC Scientists in the US"

The CDC has discovered evidence of a unique strain of cutaneous leishmaniasis in U.S. residents with no travel history, indicating local transmission of the disease by domestic sandflies. This raises concerns that the more severe visceral leishmaniasis could establish in U.S. sandflies through imported dogs carrying the pathogen. Genetic analysis revealed a distinct genetic fingerprint of the disease in non-travelers, suggesting a locally derived strain. Cutaneous leishmaniasis can cause disfiguring scars and is mainly found in low-income countries. The CDC hopes that by identifying the emergence of locally acquired cases, it will be easier to detect the disease in new areas. Additionally, there is growing concern that imported dogs could introduce the life-threatening visceral leishmaniasis to domestic sandfly populations.

Mosquito-borne dengue emerges in California, raising concerns

An "extremely rare" case of locally acquired dengue, a mosquito-borne illness, has been reported in Pasadena, California, marking the first instance in the state not associated with international travel. Dengue is typically found in tropical and sub-tropical climates and is common in many Caribbean tourist destinations. The origin of the virus in California is still unknown. Health officials are conducting surveillance and advising residents to take preventive measures against mosquito-borne illnesses. While the risk of exposure is low, dengue can cause severe symptoms in some cases, including internal bleeding and death.

Unprecedented Dengue Virus Case Detected in California

The first locally acquired case of dengue virus, also known as "break-bone fever," has been reported in Pasadena, California. This is an extremely rare case of local transmission in the continental United States, not associated with travel. Public health officials are conducting surveillance and taking preventive measures to control the spread of the virus, including mosquito population assessment and testing. While most cases of dengue virus are asymptomatic or cause mild symptoms, extreme cases can be fatal. The virus is rare in the U.S., with most cases found in travelers, but about half of the world's population is at risk of dengue, particularly in tropical and subtropical climates.

Unusual Locally-Acquired Dengue Case Detected in Southern California

The Pasadena Public Health Department has confirmed a rare case of locally-acquired dengue in a resident, marking the first instance of the illness in California not associated with travel. While the risk of exposure to dengue for residents is low, the public health department advises taking standard precautions to reduce mosquito populations and the risk of mosquito-borne diseases. Symptoms of dengue include fever, nausea, vomiting, rash, and body aches, and there are currently no specific medicines or vaccines to prevent the disease. The San Gabriel Valley Mosquito and Vector Control District has deployed traps to assess the mosquito population in the area.

Local Malaria Case Detected in Maryland Resident: Health Department

A Maryland resident in the D.C. area has been diagnosed with malaria despite not having recently traveled abroad or to states where malaria is prevalent. This "locally acquired" case is the first in Maryland in over 40 years. Health officials are taking the case seriously and will investigate. The patient may have contracted malaria from a mosquito that previously bit someone who had traveled. Malaria, a mosquito-borne disease caused by a parasite, was originally eliminated from the U.S. in the early 2000s but is still treated by doctors due to travelers returning with the parasite. The risk of acquiring mosquito-transmitted malaria remains low, but precautions such as using insect repellent and wearing protective clothing are recommended.
