Telangana issues public health advisory amid El Nino conditions, urges safe water use and heat precautions

Telangana’s health department recommends several linked precautions because El Niño conditions may bring dry spells, extreme heat and water shortages. People should boil drinking water for at least one minute, or use chlorine tablets and filters. Water should be stored in clean, covered containers, with a ladle used for drawing it.

People should drink enough fluids, use ORS, lemon water or salted buttermilk, and avoid strenuous outdoor work from noon to 3 p.m. Light cotton clothing and head covering can reduce heat exposure. Leftovers should be refrigerated properly, and spoiled food should be avoided.

For mosquito control, households should empty, scrub and completely dry tanks, coolers and buckets at least weekly. Emergency water containers must stay covered. These steps matter because the department expects higher risks of water-borne disease, heat illness, food spoilage and dengue or chikungunya transmission.

El Niño is a naturally recurring climate pattern involving unusually warm surface waters in the central and eastern tropical Pacific Ocean. The article does not define the term, but established climate science links it to changes in winds, clouds and atmospheric circulation. Those changes can affect weather far beyond the Pacific.

For example, altered circulation may shift storm tracks and weaken or redirect seasonal rainfall in some regions. It can also increase the likelihood of unusually hot conditions by changing how heat moves through the atmosphere. The exact effects differ by location and season, so El Niño does not create the same weather everywhere.

In Telangana, the advisory connects changing climatic conditions with prolonged dry spells, extreme heat and acute water shortage. These conditions can increase risks of dehydration, water-borne disease, food spoilage and stress. The department’s guidance focuses on preparedness rather than predicting one precise local outcome.

El Niño operates on a regional-to-global scale because tropical Pacific Ocean temperatures influence atmospheric circulation. The article does not explain this climate mechanism, but established climate science shows that changes in Pacific heating can alter winds, pressure patterns and the movement of storms. Weather impacts can therefore extend thousands of kilometres.

A single locality may experience heat or dryness as part of a wider regional pattern. For instance, a changed circulation pattern can reduce rainfall across a broad area while raising temperatures over many communities. Effects depend on season, geography and the strength of the El Niño event, so neighboring regions can still experience different conditions.

The Telangana advisory reflects this wider concern by warning of prolonged dry spells, extreme heat and acute water shortage. It also anticipates health effects across communities, including water-borne diseases, heat illness, malnutrition and mental stress. Preparedness must therefore involve households and public health facilities.

Prolonged heat and water shortages can leave people dehydrated, especially when they lose fluids through sweating and cannot replace them safely. Heat-related illness may follow. If available water is contaminated, people face a higher risk of water-borne disease. The advisory also identifies malnutrition and mental stress as possible risks during changing climatic conditions.

Food safety can deteriorate when high temperatures accelerate spoilage. Eating improperly refrigerated leftovers may cause illness, while shortages can reduce access to nutritious food. The department recommends seasonal fruits and vegetables with high water content, including cucumbers, melons, oranges and gourds, to support hydration and nutrition.

These risks are especially important for infants, pregnant women, older people and those with heart or blood-pressure conditions. Telangana has arranged special beds, intravenous fluids and essential medicines at public facilities. ORS sachets are also available through ANMs, ASHAs and Anganwadi workers for emergencies.

Water may look clean while still containing harmful germs or other contamination. Boiling drinking water for at least one minute helps destroy many disease-causing microorganisms. Chlorine tablets disinfect water chemically, while filters remove many contaminants, depending on the filter. These methods lower the risk of water-borne illness.

Safe handling after treatment is equally important. Storing water in clean, covered containers protects it from dust, insects and contact with dirty hands. Using a ladle instead of dipping hands into the container reduces the chance of reintroducing contamination. The advisory also says to avoid unpurified water from wells, tankers and surface water bodies.

These precautions matter more during dry spells and shortages, when people may rely on unregulated sources. Telangana advises purification even when water appears clean. The guidance combines treatment, hygienic storage and careful use, rather than depending on appearance alone.

During extreme heat, the body loses water and salts through sweating. Telangana’s advisory recommends drinking sufficient water and supplementing it with Oral Rehydration Salts, homemade lemon water or buttermilk with a pinch of salt. These options can make fluid replacement more useful than relying only on plain water.

ORS is designed to provide fluids together with electrolytes, helping replace salts lost during dehydration. Lemon water adds fluid and can be easier to drink, while salted buttermilk supplies fluid and some salt. The advisory presents these as practical choices during heat, not as substitutes for medical care in severe illness.

People should still avoid alcohol, highly caffeinated tea or coffee and sugary carbonated drinks because the department says they can contribute to fluid loss. Infants, pregnant women, older people and those with heart or blood-pressure conditions need special care. Medical help may be needed if symptoms become serious.

Stagnant water in tanks, coolers, buckets and other containers gives mosquitoes a place to lay eggs and allows their immature stages to develop. An uncovered container is especially vulnerable because mosquitoes can reach the water. The article links these breeding sites with vector-borne diseases such as dengue and chikungunya.

For example, a household cooler or emergency storage vessel may retain water for days. If it is not emptied and cleaned, mosquitoes may breed there. Covering emergency containers blocks access, while emptying, scrubbing and completely drying tanks, coolers and buckets removes water and residues that support breeding.

The department recommends carrying out this cleaning at least once a week. That routine is part of wider preparedness for dry spells and water shortages, when households may store more water. Safe storage must therefore balance conservation with mosquito control: containers should remain covered, and reusable ones should be cleaned and dried regularly.
