Heat waves are intense weather events that last for an extended length of time and are frequently accompanied by high humidity. These events can have a substantial influence on human health, including raising the likelihood of infectious disease transmission.

High temperatures and humidity can promote pathogen survival and dissemination while also exacerbating pre-existing health issues, resulting in an increased incidence of infectious or non-infectious disorders.

Here is a list of illnesses that are typical during this season and advice on how to lessen their consequences:

1. Viral Diseases: Certain viruses, such as Rubella and enterovirus, can frequently produce self-limiting sickness in otherwise healthy people. These conditions are difficult to distinguish based just on symptoms, and they are commonly treated symptomatically. Even viral respiratory infections, hepatitis, and conjunctivitis are more likely during the warm months.

2. Skin problems: Such as fungal infections and ringworm infections, are more likely in warm temperatures following a session of sweating. As a result, it is prudent to practice good hygiene, such as keeping the skin dry and clean. An infected individual's personal goods, like towels, razors, and clothing, must not be shared with others, and the patient must be properly treated to control the infection.

3. Weakens the Immune System: Eating patterns can also have an impact on the immune system's adaptive response. Studies have revealed that severe heat stress can damage the immune system's ability to combat illness and mount an effective response to immunization. 

4. Hyperthermia and heat stroke: They are described as an increase in core body temperature above the typical diurnal range. It occurs due to a breakdown in regular body thermoregulation. It could be either non-exertional or exertional. Heat from exercise Illness typically affects young and otherwise healthy people who work in hot weather; construction workers, firefighters, mountain climbers, and athletes are prominent victims.

5. Gastrointestinal diseases: Symptoms of gastrointestinal ailments typically include nausea, vomiting, loose movements, and abdominal pain. Food poisoning, such as viral diarrhea, cholera, and enteric fever, is more common in the summer. They occur when people consume contaminated food or water. It is critical to use extreme caution when consuming hygienic food and safe water. These disorders can cause consequences such as dehydration and multi-system involvement.
