Sonia Gandhi, president of the Congress party heading the ruling coalition in India, is likely to remain in hospital over the weekend.
She was admitted to the Gangaram Hospital in the national capital of New Delhi Tuesday when she complained of breathlessness and low-grade fever, accompanied by cough and cold.
She is being treated for pneumonitis, or an inflammation of the lung tissue. The Times of India reports that her condition is not seen to be life-threatening and that it is often reported in winters.
Thursday she underwent a CAT scan. Her condition is stated to be steadily improving.
Sonia has been put on antibiotics and bronchodilator medicines. Bronchodilators relieve asthma symptoms by relaxing muscle bands that tighten around the airways. This action rapidly opens the airways, letting more air flow in and out of the lungs which helps improve breathing. They also help clear mucus from the lungs.
