Kerala is once again making headlines due to infectious diseases and health concerns. The state is currently witnessing a "double attack" of infectious diseases. A report published in *Amar Ujala* on Monday (June 8) highlighted that Shigella infection has become a cause for concern among experts in the region; it has already claimed the life of a four-year-old child. Following this, there are now reports of rising West Nile virus infections in various parts of the state. The simultaneous spread of two distinct infections is placing increasing pressure on healthcare services.

The risk of various viral and bacterial infections rises during the monsoon and humid weather. While the Shigella and West Nile infections currently spreading in Kerala differ in nature and transmission methods, their simultaneous emergence poses a significant challenge for the health department.

Health experts are consistently advising the public to exercise caution, consume clean water, and take measures to protect themselves against mosquitoes. Let us take a closer look at both these diseases.

**Update on Shigella and West Nile Fever**

Shigella infection is a bacterial disease that spreads primarily through contaminated water and food. It affects the stomach and intestines and, in severe cases, can leave the body extremely weak. In contrast, the West Nile virus is a mosquito-borne viral infection transmitted through the bite of infected mosquitoes; it can lead to conditions as serious as encephalitis (inflammation of the brain).

Regarding the Shigella outbreak, health officials report that symptoms associated with the infection have been observed in 339 people so far. Of these, 59 individuals are undergoing treatment at various hospitals. Officials state that none of the patients are currently in critical condition. A total of 21 samples were sent for laboratory testing; two have tested positive so far, while results for the remaining samples are awaited.

Meanwhile, health authorities have issued a high alert in Ernakulam district following the death of a 70-year-old man due to West Nile fever. This is the second death in the district within a week caused by this mosquito-borne disease. The Kerala Health Department has urged the public to remain vigilant and actively participate in mosquito control efforts to reduce the risk of infection.

**Understanding Shigella Infection**

Shigella infection is a bacterial disease caused by the *Shigella* bacterium. It primarily spreads through the fecal-oral route—meaning, through contact with microorganisms present in the stool of an infected person. The risk arises from consuming contaminated water or food, or through direct contact with an infected individual.

Children, the elderly, and individuals with weakened immune systems are at a higher risk of contracting the disease and developing severe complications. Patients experience symptoms such as severe diarrhea (sometimes bloody), abdominal pain, fever, vomiting, and physical weakness.

In many cases, it can lead to dehydration, further aggravating the condition and potentially requiring hospitalization.

**West Nile Virus and Associated Risks**

While Shigella infection spreads through contaminated food or water, the West Nile virus is a mosquito-borne viral infection. This virus is primarily found in birds and is transmitted to humans via mosquitoes.

In most cases, the infection is mild or asymptomatic; however, in some instances, it can lead to severe neurological disease. Patients may experience fever, headache, body aches, fatigue, and skin rashes.

In severe cases, the virus can affect the brain, potentially causing encephalitis or meningitis.
