Spain reports the first case of dual infection of a Covid-19 patient Also from West Nile VirusThis is a 41-year-old man who was hospitalized with Sars-CoV-2 infection at the Virgen del Rocío Hospital in Seville. After showing symptoms consistent with meningitis, he underwent appropriate examinations. The results Shows that he is also against West Nile virus.
Covid patient has first double infection
According to a report by Salvador Oyonarte, a member of the Scientific Committee of Blood Transfusion Safety of the Ministry of Health of Andalusia, the head of Andalusian blood transfusion medicine, tissue and cell network, and hematologist Salvador Oyonarte, the Ministry of Health of Andalusia confirmed the co-infection . “No other reports Co-infected patients -Say Oyonarte -. Affected patients present atypical clinical manifestations, so it is very important to track the date of symptom onset“.
It is not clear when the patient first developed symptoms of West Nile virus infection, or whether the health conditions caused by Covid-19 made him more susceptible to meningoencephalitis caused by Nile fever. “It is difficult to know that he is a young man, and it is not yet certain whether he was infected with the coronavirus for the first time or was bitten by a mosquito while at home.” Added Oyonart.
However, what has attracted the most attention of experts is the time of year when the infection occurred, especially this case. Not before, As in the past, came from reporting infections of other animals, especially birds and horses. “The virus will spread when there are more mosquitoes and the temperature is much higher -Explains Elisa Pérez, a veterinary virologist at the Animal Health Research Center (INIA-CISA). We don’t know if this is a coincidence or if further control tests have been performed on meningitis patients, But worryingly, the virus was discovered earlier in humans than in animals“.
According to the reconstruction of the Spanish media, the man started to feel bad Last May 25th, Experienced chest pain, did not have a fever at first, leading the doctor to think this is a seasonal allergy. The first antigen test was negative, and then the patient developed a first fever, so he was quarantined for suspicion of Covid-19 and evaluated by a molecular PCR test, which turned out to be positive. His condition, coupled with evidence of pneumonia, required hospitalization, where neurological symptoms of West Nile virus infection were found. Currently, the patient is hospitalized in the intensive care unit.
“After learning the results of the test, all agreements were initiated immediately, as were the public health measures envisaged -State the Ministry of Health in the description -. The collected clinical samples will be sent to the reference laboratory (Virgen de las Nieves Hospital in Granada) and the National Microbiology Center“.
West Nile virus, a pathogen belonging to the genus Flavivirus It also includes yellow fever virus, St. Louis encephalitis virus, Murray Valley encephalitis virus and Japanese encephalitis virus, which are mainly transmitted by different kinds of mosquitoes, especially those belonging to CulexTherefore, all factors conducive to mosquito reproduction, such as stagnant water and high temperature weather conditions, may lead to increased infections. In temperate regions, cases generally occur in late summer and early autumn, while in warmer regions, the virus can spread throughout the year.
As animals, birds play a decisive role in the spread of the virus Most commonly infected And represents the first source of infection.Mosquitoes, especially Culex mosquitoes, are infected by biting birds and can therefore be infected by biting Pass to other animals, Including men. In Spain, during the transition period between the first and second waves of Covid-19 last summer, an outbreak along the Guadalquivir River was confirmed, particularly in the provinces of Seville and Cádiz, causing 71 infections , Resulting in seven deaths. Some human infections have also occurred in Italy, and the latest report dates back to September 2019.
