Tirupati had 59 dengue cases since January: DM&HO
The DM&HO explained that dengue is a viral infection spread by the bite of an infected Aedes mosquito. Symptoms include high fever, joint pain, headache, and rashes, with severe cases leading to internal bleeding or even death. He warned about Dengue Hemorrhagic Fever, a serious complication that poses higher risks to children, the elderly, and those with weak immunity.
He urged the public to eliminate stagnant clean water in coolers, flower pots, buckets, and water tanks where mosquitoes breed. The rally saw participation from several health officials including Dr Srinivasulu Reddy (DLATO), Dr GK Roop Kumar (Malaria Officer), Dr Murali Krishna (Dy DM&HO), ANMs, ASHA workers, and other staff.

Is It True That Dengue Mosquitoes Only Bite In The Morning?
Last Updated: In the fight against dengue, accurate information is as important as medical care because prevention begins with knowledge. Hospitals have seen a rapid surge in dengue cases in recent times. With this rising trend comes a common question: Do dengue mosquitoes really bite only in the morning? Dr Ajay Nair, Sr Consultant, Internal Medicine, Narayana Hospital, Jaipur shares all you need to know: Understanding Dengue and Its Carrier Dengue fever is caused by the bite of mosquitoes carrying the dengue virus (DENV) and is transmitted primarily by Aedes aegypti and, to a lesser extent, Aedes albopictus mosquitoes. These vectors are well-adapted to urban environments, thriving in stagnant water around homes, offices, and public spaces. Once infected, the mosquito can remain a carrier for its lifetime, transmitting the virus to humans every time it bites. Unlike malaria, which is spread by Anopheles mosquitoes active at night, Aedes mosquitoes cannot be linked to a single time frame, as their biting patterns vary. This often causes confusion about the timing of their bites. The Feeding Habits: Science Over Assumptions The peak activity of the Aedes aegypti mosquito has been recorded in the early morning and late afternoon, as documented in multiple entomological studies, including those published by the World Health Organization (WHO) and the National Vector Borne Disease Control Programme of India. The highest activity typically occurs for about two hours after sunrise and several hours before sunset. However, their bites do not occur only in the morning. While early daylight hours see the most concentrated activity, Aedes mosquitoes can bite throughout the day, particularly in shaded indoor areas with low light. Dengue cases typically rise during the monsoon, when breeding sites multiply and mosquito activity remains high almost throughout the day until evening. This flexibility increases the chances of virus transmission, especially in densely populated areas. Clearing the Misconception The belief that dengue mosquitoes bite only in the morning likely stems from early observations showing higher bite counts after sunrise. While this is statistically accurate as a trend, it is not the whole picture. People are still at risk during other active hours, particularly in the late afternoon and early evening. Prevention: Beyond the Clock Since the Aedes mosquito's activity is not limited to one specific time of day, dengue prevention must be a continuous effort. Medical recommendations from Narayana Health Hospital include: Controlling the surroundings Make it a habit to empty stagnant water from containers such as flower pots, buckets, utensils in the sink, discarded tyres, and open storage tanks. Frequently change water in plant trays and bird baths, and always cover stored water. Remember, Aedes mosquitoes breed in clean water too. Installing physical barriers Use mesh screens for doors and windows, wear long-sleeved clothing, and keep doors closed during peak mosquito activity. Using repellents Apply mosquito repellent creams or sprays on exposed skin every few hours during daylight, not just in the morning. Alternatively, use mosquito nets. Community action Participate in neighbourhood clean-up drives to remove puddles and water collected in discarded items. Fumigation can also help reduce mosquito populations. Prevention during travel When visiting dengue-hit areas or places experiencing heavy rains, ensure you are protected from bites regardless of the time of day. Why Awareness Matters Millions worldwide suffer from the effects of dengue fever, with India bearing a significant share of the global burden. Misunderstanding mosquito behaviour can lead to carelessness, inadvertently increasing infection rates. The idea that dengue mosquitoes bite exclusively in the morning oversimplifies their complex behaviour. While Aedes aegypti activity may peak just after sunrise and before sunset, bites can occur at other times too. Public health protection relies not on a specific 'danger hour," but on vigilance from dawn to dusk. By consistently following preventive measures, individuals and communities can significantly reduce transmission. In the fight against dengue, accurate information is as important as medical care because prevention begins with knowledge. First Published: Disclaimer: Comments reflect users' views, not News18's.

Over 3 lakh children to be administered deworming tablets in Eluru district
The National Deworming Day (NDD) programme will be held in Eluru district on August 12 (Tuesday) covering all children between the ages 1 and 19 across anganwadi centres, government and government-aided primary, upper primary, high schools, intermediate colleges, ITIs, and first-year degree colleges. Eluru DM&HO P.J. Amrutam in a press release on Monday said that a total of 3,76,263 children will be administered Albendazole tablets to eliminate intestinal worms, such as roundworms, hookworms, whipworms, and tapeworms, with the aim of improving their overall health and development. Children between the age of 1 to 2 would be given half a tablet (200 mg), while those between 2 and 19 full tablet (400 mg). The programme will be implemented through ASHA workers, anganwadi staff, and ANMs in primary and upper primary schools, and through male and female health supervisors in high schools, residential schools, ashram schools, model schools, KGBVs, gurukuls, minority institutions, intermediate colleges, and degree colleges. The tablets will be given after lunch. Teachers, cooks, and staff will be given the tablets first, followed by the students. For those absent on August 12, a 'Mop-up Day' will be conducted on August 20 to ensure complete coverage. The initiative will be monitored at the primary health centre (PHC) level by medical officers and at the mandal level by Mandal Education Officers and CDPOs (Anganwadi Project Officers). Departments including Education, Medical and Health, Women and Child Welfare, Rural Development, Zilla Parishad, Municipal Commissioners, Welfare Hostel authorities, and other concerned officials will participate to ensure 100 per cent implementation of the programme, she added.

Bangladesh dengue deaths top 100, August could be worse
Dhaka: Bangladesh is experiencing a surge in dengue cases and deaths, with health experts warning that August could bring an even more severe outbreak of the mosquito-borne disease if urgent action is not taken. Dengue has killed 101 people and infected 24,183 so far this year, official data showed, placing a severe strain on the country's already overstretched healthcare system. A sharp rise in fatalities has accompanied the spike in cases. Nineteen people have already died of dengue so far in August, following 41 deaths in July - more than double June's 19 fatalities. "The situation is critical. The virus is already widespread across the country, and without aggressive intervention, hospitals will be overwhelmed," said Kabirul Bashar, an entomologist at Jahangirnagar University. "August could see at least three times as many cases as July, with numbers potentially peaking in September." Health officials are urging people to use mosquito repellents, sleep under nets, and eliminate stagnant water where mosquitoes breed. "We need coordinated spraying and community clean-up drives, especially in high-risk zones," Bashar said. Experts say climate change, along with warm, humid weather and intermittent rain, has created ideal breeding conditions for Aedes mosquitoes, the carriers of the dengue virus. While Dhaka remains a major hotspot, dengue is peaking across the country. Large numbers of infections are being reported from outside the capital, adding pressure to rural healthcare facilities with limited capacity to treat severe cases. Doctors warn that early medical attention is critical. Severe abdominal pain, vomiting, bleeding, or extreme fatigue should prompt immediate hospital visits to reduce the risk of complications or death. With the peak dengue season still ahead, health experts have stressed that community participation, alongside government-led mosquito control, will be critical in preventing what could become one of Bangladesh's worst outbreaks in years. The deadliest year on record was 2023, with 1,705 deaths and more than 321,000 infections reported.
